it faces the same daunting task that confronted Carl Bosch a century ago: How much can it bring costs down? And how fast can it scale up

They believe that over the next seven years they can bring expenses down to a level that would enable them to sell CO₂ into more lucrative markets. Air-captured CO₂ can be combined with hydrogen and then fashioned into any kind of fossil-fuel substitute you want. Instead of making bread from air, you can make fuels from air.

What Gebald and Wurzbacher really want to do is to pull vast amounts of CO₂ out of the atmosphere and bury it, forever, deep underground, and sell that service as an offset

companies like Climeworks face a quandary: How do you sell something that never existed before, something that may never be cheap, into a market that is not yet real?

It’s arguably the case, in fact, that when it comes to reducing our carbon emissions, direct air capture will be seen as an option that’s too expensive and too modest in impact. “The only way that direct air capture becomes meaningful is if we do all the other things we need to do promptly,” Hal Harvey, a California energy analyst who studies climate-friendly technologies and policies, told me

In short, the best way to start making progress toward a decarbonized world is not to rev up millions of air capture machines right now. It’s to stop putting CO₂ in the atmosphere in the first place.

If the nations of the world were to continue on the current track, it would be impossible to meet the objectives of the 2016 Paris Agreement, which set a goal limiting warming to 2 degrees Celsius or, ideally, 1.5 degrees. And it would usher in a world of misery and economic hardship. Already, temperatures in some regions have climbed more than 1 degree Celsius, as a report by the Intergovernmental Panel on Climate Change noted last October. These temperature increases have led to an increase in droughts, heat waves, floods and biodiversity losses and make the chaos of 2 or 3 degrees’ additional warming seem inconceivable

A further problem is that maintaining today’s emissions path for too long runs the risk of doing irreparable damage to the earth’s ecosystems — causing harm that no amount of technological innovation can make right. “There is no reverse gear for natural systems,” Harvey says. “If they go, they go. If we defrost the tundra, it’s game over.” The same might be said for the Greenland and West Antarctic ice sheets, or our coral reefs. Such resources have an asymmetry in their natural architectures: They can take thousands or millions of years to form, but could reach conditions of catastrophic decline in just a few decades.

To have a shot at maintaining a climate suitable for humans, the world’s nations most likely have to reduce CO₂ emissions drastically from the current level — to perhaps 15 billion or 20 billion metric tons per year by 2030; then, through some kind of unprecedented political and industrial effort, we need to bring carbon emissions to zero by around 2050

To preserve a livable environment we may also need to extract CO₂ from the atmosphere. As Wurzbacher put it, “if you take all these numbers from the I.P.C.C., you end up with something like eight to 10 billion tons — gigatons — of CO₂ that need to be removed from the air every year, if we are serious about 1.5 or 2 degrees.

Through photosynthesis, our forests take extraordinary amounts of carbon dioxide from the atmosphere, and if we were to magnify efforts to reforest clear-cut areas — or plant new groves, a process known as afforestation — we could absorb billions more metric tons of carbon in future years.

we could grow crops specifically to absorb CO₂ and then burn them for power generation, with the intention of capturing the power-plant emissions and pumping them underground, a process known as bioenergy with carbon capture and storage, or BECCS

Ever since the Industrial Revolution, human societies have produced an excess of CO₂, by taking carbon stores from deep inside the earth — in the form of coal, oil and gas — and from stores aboveground (mostly wood), then putting it into the atmosphere by burning it. It has become imperative to reverse the process — that is, take CO₂ out of the air and either restore it deep inside the earth or contain it within new surface ecosystems.

“It’s not about saying, ‘I want to plant a tree.’ It’s about saying, ‘We want to plant a billion trees.’

“We have to come to grips with the fact that we waited too long and that we took some options off the table,” Michael Oppenheimer, a Princeton scientist who studies climate and policy, told me. As a result, NETs no longer seem to be just interesting ideas; they look like necessities. And as it happens, the Climeworks machines on the rooftop do the work each year of about 36,000 trees.

air capture could likewise help counter the impact of several vital industries. “There are process emissions that come from producing iron and steel, cement and glass,” she says, “and any time you make these materials, there’s a chemical reaction that emits CO₂.” Direct air capture could even lessen the impacts of the Haber-Bosch processes for making fertilizer; by some estimates, that industry now accounts for 3 percent of all CO₂ emissions.

Wind and solar are now the cheapest forms of energy in the right locations,” Pacala says. “The return on those investments, if you calculated it, would blow the doors off anything in your portfolio. It’s like investing in early Apple. So it’s a spectacular story of success. And direct air capture is precisely the same kind of problem, in which the only barrier is that it’s too costly.”

what all the founders have in common is a belief that the cost of capturing a ton of carbon will soon drop sharply.

M.I.T.’s Howard Herzog, for instance, an engineer who has spent years looking at the potential for these machines, told me that he thinks the costs will remain between $600 and $1,000 per metric ton

He points out that because direct-air-capture machines have to move tremendous amounts of air through a filter or solution to glean a ton of CO₂ — the gas, for all its global impact, makes up only about 0.04 percent of our atmosphere — the process necessitates large expenditures for energy and big equipment. What he has likewise observed, in analyzing similar industries that separate gases, suggests that translating spreadsheet projections for capturing CO₂ into real-world applications will reveal hidden costs. “I think there has been a lot of hype about this, and it’s not going to revolutionize anything,

Climeworks’s current goal is to remove 1 percent of the world’s annual CO₂ emissions by the mid 2020s.

“Basically, we have a road map — $600, down to $400, down to $300 and $200 a ton,” Wurzbacher said. “This is over the next five years. Down to $200 we know quite well what we’re doing.” And beyond $200, Wurzbacher suggested, things get murkier.

To actually capture 1 percent of the world’s carbon emissions by 2025 would, by Gebald’s calculations, require that Climeworks build 250,000 carbon-capture plants like the ones on the roof at Hinwil. That adds up to about 4.5 million carbon collectors

The Climeworks founders therefore try to think of their product as the automotive industry might — a piece of mass-produced technology and metal, not the carbon they hope to sequester.

“Every CO₂ collector has about the same weight and dimensions of a car — roughly two tons, and roughly 2 meters by 2 meters by 2 meters,” Gebald said. “And all the methods used to produce the CO₂ collectors could be well automated. So we have the automotive industry as a model for how to produce things in large quantities for low cost.

n 1954, the economist Paul Samuelson put forward a theory that made a distinction between “private-consumption goods” — bread, cars, houses and the like — and commodities that existed apart from the usual laws of supply and demand.

the other type of commodity Samuelson was describing is something now known as a “public good,” which benefits everyone but is not bought, sold or consumed the same way

direct air capture’s success would be limited to the size of the market for private goods — soda fizz, greenhouse gas — unless governments decided to intervene and help fund the equivalent of several million (or more) lighthouses.

An intervention could take a variety of forms. It could be large grants for research to find better sorbent materials, for instance, which would be similar to government investments that long ago helped nurture the solar- and wind-power industries. But help could also come by expanding regulations that already exist.

The Climeworks founders told me they don’t believe their company will succeed on what they call “climate impact” scales unless the world puts significant prices on emissions, in the form of a carbon tax or carbon fee.

“Our goal is to make it possible to capture CO₂ from the air for below $100 per ton,” Wurzbacher says. “No one owns a crystal ball, but we think — and we’re quite confident — that by something like 2030 we’ll have a global average price on carbon in the range of $100 to $150 a ton.” There is optimism in this thinking

A company that sells a product or uses a process that creates high emissions — an airline, for instance, or a steel maker — could be required to pay carbon-removal companies $100 per metric ton or more to offset their CO₂ output. Or a government might use carbon-tax proceeds to directly pay businesses to collect and bury CO₂.

“It doesn’t cost too much to pump CO₂ underground,” Stanford’s Sally Benson says. Companies already sequester about 34 million metric tons of CO₂ in the ground every year, at a number of sites around the world, usually to enhance the oil-drilling process. “The costs range from $2 to $15 per ton. So the bigger cost in all of this is the cost of carbon capture.”

The weekend before, Gutknecht told me, he received 900 unsolicited inquiries by email. Many were from potential customers who wanted to know how soon Climeworks could bury their CO₂ emissions, or how much a machine might cost them.

A Climeworks app could be installed on my smartphone, he explained. It could then be activated by my handset’s location services. “You fly over here to Europe,” he explained, “and the app tells you that you have just burned 1.7 tons of CO₂. Do you want to remove that? Well, Climeworks can remove it for you. Click here. We’ll charge your credit card.

The vast and constant market demand for fuel is why Carbon Engineering has staked its future on synthetics. The world currently burns about 100 million barrels of oil a day.

“So let’s say you’d have to supply something like 50 million barrels a day in 2050 of fuels,” he said. “That’s still a monster market.”

Carbon Engineering’s chief executive, added that direct-air-capture synthetics have an advantage over traditional fossil fuels: They won’t have to spend a dime on exploration

our plants, you can build it right in the middle of California, wherever you have air and water.” He told me that the company’s first large-scale facility should be up and running by 2022, and will turn out at least 500 barrels a day of fuel feedstock — the raw material sent to refineries.

Climeworks recently joined a consortium of European countries to produce synthetic methane that will be used by a local trucking fleet. With different tweaks and refinements, the process could be adapted for diesel, gasoline, jet fuel — or it could be piped directly to local neighborhoods as fuel for home furnaces.

the new fuels are not necessarily cheaper. Carbon Engineering aspires to deliver its product at an ultimate retail price of about $1 per liter, or $3.75 per gallon. What would make the product competitive are regulations in California that now require fuel sellers to produce fuels of lower “carbon intensity.” To date this has meant blending gas and diesel with biofuels like ethanol, but it could soon mean carbon-capture synthetics too.

Since they’re made from airborne CO₂ and hydrogen and could be manufactured just about anywhere, they could rearrange the geopolitical order — tempering the power of a handful of countries that now control natural-gas and oil markets.

From an environmental standpoint, air-capture fuels are not a utopian solution. Such fuels are carbon neutral, not carbon negative. They can’t take CO₂ from our industrial past and put it back into the earth

Even so, these fuels could present an enormous improvement. Transportation — currently the most significant source of emissions by sector in the United States — could cease to be a net emitter of CO₂

“If you can do one carbon-capture facility, where Carbon Engineering or Climeworks can build a big plant, great. You need to do that 5,000 times. And to capture a million tons of CO₂ with direct air capture, you need a small power plant just to run that facility. So if you’re going to build one direct-air-capture facility every day for the next 30 years to get to some of these scenarios, then in addition, we have to build a new mini power plant every day as well.

It’s also the case that you have to address two extraordinary problems at the same time, Peters added. “To reach 1.5 degrees, we need to halve emissions every decade,” he said. That would mean persuading entire nations, like China and the United States, to switch from burning coal to using renewables at precisely the same time that we make immense investments in negative-emission technologies.

this would need to be done even as governments choose among competing priorities:

“The idea of bringing direct air capture up to 10 billion tons by the middle or later part of the century is such a herculean task it would require an industrial scale-up the likes of which the world has never seen,”

Pacala wasn’t pessimistic about making a start. He seemed to think it was necessary for the federal government to begin with significant research and investments in the technology — to see how far and fast it could move forward, so that it’s ready as soon as possible

Gebald and Wurzbacher seemed to regard the climate challenge in mathematical terms. How many gigatons needed to be removed? How much would it cost per ton? How many Climeworks machines were required? Even if the figures were enormous, even if they appeared impossible, to see the future their way was to redefine the problem, to move away from the narrative of loss, to forget the multiplying stories of dying reefs and threatened coastlines — and to begin to imagine other possibilities.

that’s particularly true on the I.R.A., which has to build all these things in the real world.

we’re trying to do industrial physical transformation at a speed and scale unheralded in American history. This is bigger than anything we have done at this speed ever.

The money is beginning to move out the door now, but we’re on a clock. Climate change is not like some other issues where if you don’t solve it this year, it is exactly the same to solve it next year. This is an issue where every year you don’t solve it, the amount of greenhouse gases in the atmosphere builds, warming builds, the effects compound

Solve, frankly, isn’t the right word there because all we can do is abate, a lot of the problems now baked in. So how is it going, and who can actually walk us through that?

Robinson Meyer is the founding executive editor of heatmap.news

why do all these numbers differ so much? How big is this thing?

in electric vehicles and in the effort, kind of this dual effort in the law, to both encourage Americans to buy and use electric vehicles and then also to build a domestic manufacturing base for electric vehicles.

on both counts, the data’s really good on electric vehicles. And that’s where we’re getting the fastest response from industry and the clearest response from industry to the law.

ROBINSON MEYER: Factories are getting planned. Steel’s going in the ground. The financing for those factories is locked down. It seems like they’re definitely going to happen. They’re permitted. Companies are excited about them. Large Fortune 500 automakers are confidently and with certainty planning for an electric vehicle future, and they’re building the factories to do that in the United States. They’re also building the factories to do that not just in blue states. And so to some degree, we can see the political certainty for electric vehicles going forward.

in other parts of the law, partially due to just vagaries of how the law is being implemented, tax credits where the fine print hasn’t worked out yet, it’s too early to say whether the law is working and how it’s going and whether it’s going to accomplish its goal

EZRA KLEIN: I always find this very funny in a way. The Congressional Budget Office scored it. They thought it would make about $380 billion in climate investments over a decade. So then you have all these other analyses coming out.

But there’s actually this huge range of outcomes in between where the thing passes, and maybe what you wanted to have happen happens. Maybe it doesn’t. Implementation is where all this rubber meets the road

the Rhodium Group, which is a consulting firm, they think it could be as high as $522 billion, which is a big difference. Then there’s this Goldman Sachs estimate, which the administration loves, where they say they’re projecting $1.2 trillion in incentives —

ROBINSON MEYER: All the numbers differ because most of the important incentives, most of the important tax credits and subsidies in the I.R.A., are uncapped. There’s no limit to how much the government might spend on them. All that matters is that some private citizen or firm or organization come to the government and is like, hey, we did this. You said you’d give us money for it. Give us the money.

because of that, different banks have their own energy system models, their own models of the economy. Different research groups have their own models.

we know it’s going to be wrong because the Congressional Budget Office is actually quite constrained in how it can predict how these tax credits are taken up. And it’s constrained by the technology that’s out there in the country right now.

The C.B.O. can only look at the number of electrolyzers, kind of the existing hydrogen infrastructure in the country, and be like, well, they’re probably all going to use these tax credits. And so I think they said that there would be about $5 billion of take up for the hydrogen tax credits.

But sometimes money gets allocated, and then costs overrun, and there delays, and you can’t get the permits, and so on, and the thing never gets built

the fact that the estimates are going up is to them early evidence that this is going well. There is a lot of applications. People want the tax credits. They want to build these new factories, et cetera.

a huge fallacy that we make in policy all the time is assuming that once money is allocated for something, you get the thing you’re allocating the money for. Noah Smith, the economics writer, likes to call this checkism, that money equals stuff.

EZRA KLEIN: They do not want that, and not wanting that and putting every application through a level of scrutiny high enough to try and make sure you don’t have another one

I don’t think people think a lot about who is cutting these checks, but a lot of it is happening in this very obscure office of the Department of Energy, the Loan Program Office, which has gone from having $40 billion in lending authority, which is already a big boost over it not existing a couple decades ago, to $400 billion in loan authority,

the Loan Program Office as one of the best places we have data on how this is going right now and one of the offices that’s responded fastest to the I.R.A.

the Loan Program Office is basically the Department of Energy’s in-house bank, and it’s kind of the closest thing we have in the US to what exists in other countries, like Germany, which is a State development bank that funds projects that are eventually going to be profitable.

It has existed for some time. I mean, at first, it kind of was first to play after the Recovery Act of 2009. And in fact, early in its life, it gave a very important loan to Tesla. It gave this almost bridge loan to Tesla that helped Tesla build up manufacturing capacity, and it got Tesla to where it is today.

EZRA KLEIN: It’s because one of the questions I have about that office and that you see in some of the coverage of them is they’re very afraid of having another Solyndra.

Now, depending on other numbers, including the D.O.E., it’s potentially as high as $100 billion, but that’s because the whole thing about the I.R.A. is it’s meant to encourage the build-out of this hydrogen infrastructure.

EZRA KLEIN: I’m never that excited when I see a government loans program turning a profit because I think that tends to mean they’re not making risky enough loans. The point of the government should be to bear quite a bit of risk —

And to some degree, Ford now has to compete, and US automakers are trying to catch up with Chinese EV automakers. And its firms have EV battery technology especially, but just have kind of comprehensive understanding of the EV supply chain that no other countries’ companies have

ROBINSON MEYER: You’re absolutely right that this is the key question. They gave this $9.2 billion loan to Ford to build these EV battery plants in Kentucky and Tennessee. It’s the largest loan in the office’s history. It actually means that the investment in these factories is going to be entirely covered by the government, which is great for Ford and great for our build-out of EVs

And to some degree, I should say, one of the roles of L.P.O. and one of the roles of any kind of State development bank, right, is to loan to these big factory projects that, yes, may eventually be profitable, may, in fact, assuredly be profitable, but just aren’t there yet or need financing that the private market can’t provide. That being said, they have moved very slowly, I think.

And they feel like they’re moving quickly. They just got out new guidelines that are supposed to streamline a lot of this. Their core programs, they just redefined and streamlined in the name of speeding them up

However, so far, L.P.O. has been quite slow in getting out new loans

I want to say that the pressure they’re under is very real. Solyndra was a disaster for the Department of Energy. Whether that was fair or not fair, there’s a real fear that if you make a couple bad loans that go bad in a big way, you will destroy the political support for this program, and the money will be clawed back, a future Republican administration will wreck the office, whatever it might be. So this is not an easy call.

when you tell me they just made the biggest loan in their history to Ford, I’m not saying you shouldn’t lend any money to Ford, but when I think of what is the kind of company that cannot raise money on the capital markets, the one that comes to mind is not Ford

They have made loans to a number of more risky companies than Ford, but in addition to speed, do you think they are taking bets on the kinds of companies that need bets? It’s a little bit hard for me to believe that it would have been impossible for Ford to figure out how to finance factorie

ROBINSON MEYER: Now, I guess what I would say about that is that Ford is — let’s go back to why Solyndra failed, right? Solyndra failed because Chinese solar deluged the market. Now, why did Chinese solar deluge the market? Because there’s such support of Chinese financing from the state for massive solar factories and massive scale.

EZRA KLEIN: — the private market can’t. So that’s the meta question I’m asking here. In your view, because you’re tracking this much closer than I am, are they too much under the shadow of Solyndra? Are they being too cautious? Are they getting money out fast enough?

ROBINSON MEYER: I think that’s right; that basically, if we think the US should stay competitive and stay as close as it can and not even stay competitive, but catch up with Chinese companies, it is going to require large-scale state support of manufacturing.

EZRA KLEIN: OK, that’s fair. I will say, in general, there’s a constant thing you find reporting on government that people in government feel like they are moving very quickly

EZRA KLEIN: — given the procedural work they have to go through. And they often are moving very quickly compared to what has been done in that respect before, compared to what they have to get over. They are working weekends, they are working nights, and they are still not actually moving that quickly compared to what a VC firm can do or an investment bank or someone else who doesn’t have the weight of congressional oversight committees potentially calling you in and government procurement rules and all the rest of it.

ROBINSON MEYER: I think that’s a theme across the government’s implementation of the I.R.A. right now, is that generally the government feels like it’s moving as fast as it can. And if you look at the Department of Treasury, they feel like we are publishing — basically, the way that most of the I.R.A. subsidies work is that they will eventually be administered by the I.R.S., but first the Department of the Treasury has to write the guidebook for all these subsidies, right?

the law says there’s a very general kind of “here’s thousands of dollars for EVs under this circumstance.” Someone still has to go in and write all the fine print. The Department of Treasury is doing that right now for each tax credit, and they have to do that before anyone can claim that tax credit to the I.R.S. Treasury feels like it’s moving extremely quickly. It basically feels like it’s completely at capacity with these, and it’s sequenced these so it feels like it’s getting out the most important tax credits first.

Private industry feels like we need certainty. It’s almost a year since the law passed, and you haven’t gotten us the domestic content bonus. You haven’t gotten us the community solar bonus. You haven’t gotten us all these things yet.

a theme across the government right now is that the I.R.A. passed. Agencies have to write the regulations for all these tax credits. They feel like they’re moving very quickly, and yet companies feel like they’re not moving fast enough.

that’s how we get to this point where we’re 311 days out from the I.R.A. passing, and you’re like, well, has it made a big difference? And I’m like, well, frankly, wind and solar developers broadly don’t feel like they have the full understanding of all the subsidies they need yet to begin making the massive investments

I think it’s fair to say maybe the biggest bet on that is green hydrogen, if you’re looking in the bill.

We think it’s going to be an important tool in industry. It may be an important tool for storing energy in the power grid. It may be an important tool for anything that needs combustion.

ROBINSON MEYER: Yeah, absolutely. So green hydrogen — and let’s just actually talk about hydrogen broadly as this potential tool in the decarbonization tool kit.

It’s a molecule. It is a very light element, and you can burn it, but it’s not a fossil fuel. And a lot of the importance of hydrogen kind of comes back to that attribute of it.

So when we look at sectors of the economy that are going to be quite hard to decarbonize — and that’s because there is something about fossil fuels chemically that is essential to how that sector works either because they provide combustion heat and steelmaking or because fossil fuels are actually a chemical feedstock where the molecules in the fossil fuel are going into the product or because fossil fuels are so energy dense that you can carry a lot of energy while actually not carrying that much mass — any of those places, that’s where we look at hydrogen as going.

green hydrogen is something new, and the size of the bet is huge. So can you talk about first just what is green hydrogen? Because my understanding of it is spotty.

The I.R.A. is extremely generous — like extremely, extremely generous — in its hydrogen subsidies

The first is for what’s called blue hydrogen, which is hydrogen made from natural gas, where we then capture the carbon dioxide that was released from that process and pump it back into the ground. That’s one thing that’s subsidized. It’s basically subsidized as part of this broader set of packages targeted at carbon capture

green hydrogen, which is where we take water, use electrolyzers on it, basically zap it apart, take the hydrogen from the water, and then use that as a fue

The I.R.A. subsidies for green hydrogen specifically, which is the one with water and electricity, are so generous that relatively immediately, it’s going to have a negative cost to make green hydrogen. It will cost less than $0 to make green hydrogen. The government’s going to fully cover the cost of producing it.

That is intentional because what needs to happen now is that green hydrogen moves into places where we’re using natural gas, other places in the industrial economy, and it needs to be price competitive with those things, with natural gas, for instance. And so as it kind of is transported, it’s going to cost money

As you make the investment to replace the technology, it’s going to cost money. And so as the hydrogen moves through the system, it’s going to wind up being price competitive with natural gas, but the subsidies in the bill are so generous that hydrogen will cost less than $0 to make a kilogram of it

There seems to be a sense that hydrogen, green hydrogen, is something we sort of know how to make, but we don’t know how to make it cost competitive yet. We don’t know how to infuse it into all the processes that we need to be infused into. And so a place where the I.R.A. is trying to create a reality that does not yet exist is a reality where green hydrogen is widely used, we have to know how to use it, et cetera.

And they just seem to think we don’t. And so you need all these factories. You need all this innovation. Like, they have to create a whole innovation and supply chain almost from scratch. Is that right?

ROBINSON MEYER: That’s exactly right. There’s a great Department of Energy report that I would actually recommend anyone interested in this read called “The Liftoff Report for Clean Hydrogen.” They made it for a few other technologies. It’s a hundred-page book that’s basically how the D.O.E. believes we’re going to build out a clean hydrogen economy.

And, of course, that is policy in its own right because the D.O.E. is saying, here is the years we’re going to invest to have certain infrastructure come online. Here’s what we think we need. That’s kind of a signal to industry that everyone should plan around those years as well.

It’s a great book. It’s like the best piece of industrial policy I’ve actually seen from the government at all. But one of the points it makes is that you’re going to make green hydrogen. You’re then going to need to move it. You’re going to need to move it in a pipeline or maybe a truck or maybe in storage tanks that you then cart around.

Once it gets to a facility that uses green hydrogen, you’re going to need to store some green hydrogen there in storage tanks on site because you basically need kind of a backup supply in case your main supply fails. All of those things are going to add cost to hydrogen. And not only are they going to add cost, we don’t really know how to do them. We have very few pipelines that are hydrogen ready.

All of that investment needs to happen as a result to make the green hydrogen economy come alive. And why it’s so lavishly subsidized is to kind of fund all that downstream investment that’s eventually going to make the economy come true.

But a lot of what has to happen here, including once the money is given out, is that things we do know how to build get built, and they get built really fast, and they get built at this crazy scale.

So I’ve been reading this paper on what they call “The Greens’ Dilemma” by J.B. Ruhl and James Salzman, who also wrote this paper called “Old Green Laws, New Green Deal,” or something like that. And I think they get at the scale problem here really well.

“The largest solar facility currently online in the US is capable of generating 585 megawatts. To meet even a middle-road renewable energy scenario would require bringing online two new 400-megawatt solar power facilities, each taking up at least 2,000 acres of land every week for the next 30 years.”

And that’s just solar. We’re not talking wind there. We’re not talking any of the other stuff we’ve discussed here, transmission lines. Can we do that? Do we have that capacity?

ROBINSON MEYER: No, we do not. We absolutely do not. I think we’re going to build a ton of wind and solar. We do not right now have the system set up to use that much land to build that much new solar and wind by the time that we need to build it. I think it is partially because of permitting laws, and I think it’s also partially because right now there is no master plan

There’s no overarching strategic entity in the government that’s saying, how do we get from all these subsidies in the I.R.A. to net zero? What is our actual plan to get from where we are right now to where we’re emitting zero carbon as an economy? And without that function, no project is essential. No activity that we do absolutely needs to happen, and so therefore everything just kind of proceeds along at a convenient pace.

given the scale of what’s being attempted here, you might think that something the I.R.A. does is to have some entity in the government, as you’re saying, say, OK, we need this many solar farms. This is where we think we should put them. Let’s find some people to build them, or let’s build them ourselves.

what it actually does is there’s an office somewhere waiting for private companies to send in an application for a tax credit for solar that they say they’re going to build, and then we hope they build it

it’s an almost entirely passive process on the part of the government. Entirely would be going too far because I do think they talk to people, and they’re having conversations

the builder applies, not the government plans. Is that accurate?

ROBINSON MEYER: That’s correct. Yes.

ROBINSON MEYER: I think here’s what I would say, and this gets back to what do we want the I.R.A. to do and what are our expectations for the I.R.A

If the I.R.A. exists to build out a ton of green capacity and shift the political economy of the country toward being less dominated by fossil fuels and more dominated by the clean energy industry, frankly, then it is working

If the I.R.A. is meant to get us all the way to net zero, then it is not capable of that.

in 2022, right, we had no way to see how we were going to reduce emissions. We did not know if we were going to get a climate bill at all. Now, we have this really aggressive climate bill, and we’re like, oh, is this going to get us to net zero?

But getting to net zero was not even a possibility in 2022.

The issue is that the I.R.A. requires, ultimately, private actors to come forward and do these things. And as more and more renewables get onto the grid, almost mechanically, there’s going to be less interest in bringing the final pieces of decarbonized electricity infrastructure onto the grid as well.

EZRA KLEIN: Because the first things that get applied for are the ones that are more obviously profitable

The issue is when you talk to solar developers, they don’t see it like, “Am I going to make a ton of money, yes or no?” They see it like they have a capital stack, and they have certain incentives and certain ways to make money based off certain things they can do. And as more and more solar gets on the grid, building solar at all becomes less profitable

also, just generally, there’s less people willing to buy the solar.

as we get closer to a zero-carbon grid, there is this risk that basically less and less gets built because it will become less and less profitable

EZRA KLEIN: Let’s call that the last 20 percent risk

EZRA KLEIN: — or the last 40 percent. I mean, you can probably attach different numbers to that

ROBINSON MEYER: Permitting is the primary thing that is going to hold back any construction basically, especially out West,

right now permitting fights, the process under the National Environmental Policy Act just at the federal level, can take 4.5 years

let’s say every single project we need to do was applied for today, which is not true — those projects have not yet been applied for — they would be approved under the current permitting schedule in 2027.

ROBINSON MEYER: That’s before they get built.

Basically nobody on the left talked about permitting five years ago. I don’t want to say literally nobody, but you weren’t hearing it, including in the climate discussion.

people have moved to saying we do not have the laws, right, the permitting laws, the procurement laws to do this at the speed we’re promising, and we need to fix that. And then what you’re seeing them propose is kind of tweak oriented,

Permitting reform could mean a lot of different things, and Democrats and Republicans have different ideas about what it could mean. Environmental groups, within themselves, have different ideas about what it could mean.

for many environmental groups, the permitting process is their main tool. It is how they do the good that they see themselves doing in the world. They use the permitting process to slow down fossil fuel projects, to slow down projects that they see as harming local communities or the local environment.

ROBINSON MEYER: So we talk about the National Environmental Policy Act or NEPA. Let’s just start calling it NEPA. We talk about the NEPA process

NEPA requires the government basically study any environmental impact from a project or from a decision or from a big rule that could occur.

Any giant project in the United States goes through this NEPA process. The federal government studies what the environmental impact of the project will be. Then it makes a decision about whether to approve the project. That decision has nothing to do with the study. Now, notionally, the study is supposed to inform the project.

the decision the federal government makes, the actual “can you build this, yes or no,” legally has no connection to the study. But it must conduct the study in order to make that decision.

that permitting reform is so tough for the Democratic coalition specifically is that this process of forcing the government to amend its studies of the environmental impact of various decisions is the main tool that environmental litigation groups like Earthjustice use to slow down fossil fuel projects and use to slow down large-scale chemical or industrial projects that they don’t think should happen.

when we talk about making this program faster, and when we talk about making it more immune to litigation, they see it as we’re going to take away their main tools to fight fossil fuel infrastructure

why there’s this gap between rhetoric and what’s actually being proposed is that the same tool that is slowing down the green build-out is also what’s slowing down the fossil fuel build-out

ROBINSON MEYER: They’re the classic conflict here between the environmental movement classic, let’s call it, which was “think globally, act locally,” which said “we’re going to do everything we can to preserve the local environment,” and what the environmental movement and the climate movement, let’s say, needs to do today, which is think globally, act with an eye to what we need globally as well, which is, in some cases, maybe welcome projects that may slightly reduce local environmental quality or may seem to reduce local environmental quality in the name of a decarbonized world.

Because if we fill the atmosphere with carbon, nobody’s going to get a good environment.

Michael Gerrard, who is professor at Columbia Law School. He’s a founder of the Sabin Center for Climate Change Law there. It’s called “A Time for Triage,” and he has this sort of interesting argument that the environmental movement in general, in his view, is engaged in something he calls trade-off denial.

his view and the view of some people is that, look, the climate crisis is so bad that we just have to make those choices. We have to do things we would not have wanted to do to preserve something like the climate in which not just human civilization, but this sort of animal ecosystem, has emerged. But that’s hard, and who gets to decide which trade-offs to make?

what you’re not really seeing — not really, I would say, from the administration, even though they have some principles now; not really from California, though Gavin Newsom has a set of early things — is “this is what we think we need to make the I.R.A. happen on time, and this is how we’re going to decide what is a kind of project that gets this speedway through,” w

there’s a failure on the part of, let’s say, the environmental coalition writ large to have the courage to have this conversation and to sit down at a table and be like, “OK, we know that certain projects aren’t happening fast enough. We know that we need to build out faster. What could we actually do to the laws to be able to construct things faster and to meet our net-zero targets and to let the I.R.A. kind achieve what it could achieve?”

part of the issue is that we’re in this environment where Democrats control the Senate, Republicans control the House, and it feels very unlikely that you could just get “we are going to accelerate projects, but only those that are good for climate change,” into the law given that Republicans control the House.

part of the progressive fear here is that the right solutions must recognize climate change. Progressives are very skeptical that there are reforms that are neutral on the existence of climate change and whether we need to build faster to meet those demands that can pass through a Republican-controlled House.

one of the implications of that piece was it was maybe a huge mistake for progressives not to have figured out what they wanted here and could accept here, back when the negotiating partner was Joe Manchin.

Manchin’s bill is basically a set of moderate NEPA reforms and transmission reforms. Democrats, progressives refuse to move on it. Now, I do want to be fair here because I think Democrats absolutely should have seized on that opportunity, because it was the only moment when — we could tell already that Democrats — I mean, Democrats actually, by that moment, had lost the House.

I do want to be fair here that Manchin’s own account of what happened with this bill is that Senate Republicans killed it and that once McConnell failed to negotiate on the bill in December, Manchin’s bill was dead.

EZRA KLEIN: It died in both places.ROBINSON MEYER: It died in both places. I think that’s right.

Republicans already knew they were going to get the House, too, so they had less incentive to play along. Probably the time for this was October.

EZRA KLEIN: But it wasn’t like Democrats were trying to get this one done.

EZRA KLEIN: To your point about this was all coming down to the wire, Manchin could have let the I.R.A. pass many months before this, and they would have had more time to negotiate together, right? The fact that it was associated with Manchin in the way it was was also what made it toxic to progressives, who didn’t want to be held up by him anymore.

What becomes clear by the winter of this year, February, March of this year, is that as Democrats and Republicans begin to talk through this debt-ceiling process where, again, permitting was not the main focus. It was the federal budget. It was an entirely separate political process, basically.

EZRA KLEIN: I would say the core weirdness of the debt-ceiling fight was there was no main focus to it.

EZRA KLEIN: It wasn’t like past ones where it was about the debt. Republicans did some stuff to cut spending. They also wanted to cut spending on the I.R.S., which would increase the debt, right? It was a total mishmash of stuff happening in there.

That alchemy goes into the final debt-ceiling negotiations, which are between principals in Congress and the White House, and what we get is a set of basically the NEPA reforms in Joe Manchin’s bill from last year and the Mountain Valley pipeline, the thing that environmentalists were focused on blocking, and effectively no transmission reforms.

the set of NEPA reforms that were just enacted, that are now in the law, include — basically, the word reasonable has been inserted many times into NEPA. [LAUGHS] So the law, instead of saying the government has to study all environmental impacts, now it has to study reasonable environmental impacts.

this is a kind of climate win — has to study the environmental impacts that could result from not doing a project. The kind of average NEPA environmental impact study today is 500 pages and takes 4.5 years to produce. Under the law now, the government is supposed to hit a page limit of 150 to 300 pages.

there’s a study that’s very well cited by progressives from three professors in Utah who basically say, well, when you look at the National Forest Service, and you look at this 40,000 NEPA decisions, what mostly holds up these NEPA decisions is not like, oh, there’s too many requirements or they had to study too many things that don’t matter. It’s just there wasn’t enough staff and that staffing is primarily the big impediment. And so on the one hand, I think that’s probably accurate in that these are, in some cases — the beast has been starved, and these are very poorly staffed departments

The main progressive demand was just “we must staff it better.”

But if it’s taking you this much staffing and that much time to say something doesn’t apply to you, maybe you have a process problem —ROBINSON MEYER: Yes.EZRA KLEIN: — and you shouldn’t just throw endless resources at a broken process, which brings me — because, again, you can fall into this and never get out — I think, to the bigger critique her

these bills are almost symbolic because there’s so much else happening, and it’s really the way all this interlocks and the number of possible choke points, that if you touch one of them or even you streamline one of them, it doesn’t necessarily get you that f

“All told, over 60 federal permitting programs operate in the infrastructure approval regime, and that is just the federal system. State and local approvals and impact assessments could also apply to any project.”

their view is that under this system, it’s simply not possible to build the amount of decarbonization infrastructure we need at the pace we need it; that no amount of streamlining NEPA or streamlining, in California, CEQA will get you there; that we basically have been operating under what they call an environmental grand bargain dating back to the ’70s, where we built all of these processes to slow things down and to clean up the air and clean up the water.

we accepted this trade-off of slower building, quite a bit slower building, for a cleaner environment. And that was a good trade. It was addressing the problems of that era

now we have the problems of this era, which is we need to unbelievably, rapidly build out decarbonization infrastructure to keep the climate from warming more than we can handle and that we just don’t have a legal regime or anything.

You would need to do a whole new grand bargain for this era. And I’ve not seen that many people say that, but it seems true to me

the role that America had played in the global economy in the ’50s and ’60s where we had a ton of manufacturing, where we were kind of the factory to a world rebuilding from World War II, was no longer tenable and that, also, we wanted to focus on more of these kind of high-wage, what we would now call knowledge economy jobs.That was a large economic transition happening in the ’70s and ’80s, and it dovetailed really nicely with the environmental grand bargain.

At some point, the I.R.A. recognizes that that environmental grand bargain is no longer operative, right, because it says, we’re going to build all this big fiscal fixed infrastructure in the United States, we’re going to become a manufacturing giant again, but there has not been a recognition among either party of what exactly that will mean and what will be required to have it take hold.

It must require a form of on-the-ground, inside-the-fenceline, “at the site of the power plant” pollution control technology. The only way to do that, really, is by requiring carbon capture and requiring the large construction of major industrial infrastructure at many, many coal plants and natural gas plants around the country in order to capture carbon so it doesn’t enter the atmosphere, and so we don’t contribute to climate change. That is what the Supreme Court has ruled. Until that body changes, that is going to be the law.

So the E.P.A. has now, last month, proposed a new rule under the Clean Air Act that is going to require coal plants and some natural gas plants to install carbon capture technology to do basically what the Supreme Court has all but kind of required the E.P.A. to do

the E.P.A. has to demonstrate, in order to kind of make this rule the law and in order to make this rule pass muster with the Supreme Court, that this is tenable, that this is the best available and technologically feasible option

that means you actually have to allow carbon capture facilities to get built and you have to create a legal process that will allow carbon capture facilities to get built. And that means you need to be able to tell a power plant operator that if they capture carbon, there’s a way they can inject it back into the ground, the thing that they’re supposed to do with it.

Well, E.P.A. simultaneously has only approved the kind of well that you need to inject carbon that you’ve captured from a coal factory or a natural gas line back into the ground. It’s called a Class 6 well. The E.P.A. has only ever approved two Class 6 wells. It takes years for the E.P.A. to approve a Class 6 well.

And environmental justice groups really, really oppose these Class 6 wells because they see any carbon capture as an effort to extend the life of the fossil fuel infrastructure

The issue here is that it seems like C.C.S., carbon capture, is going to be essential to how the U.S. decarbonizes. Legally, we have no other choice because of the constraints the Supreme Court has placed on the E.P.A.. At the same time, environmental justice groups, and big green groups to some extent, oppose building out any C.C.S.

to be fair to them, right, they would say there are other ways to decarbonize. That may not be the way we’ve chosen because the politics weren’t there for it, but there are a lot of these groups that believe you could have 100 percent renewables, do not use all that much carbon capture, right? They would have liked to see a different decarbonization path taken too. I’m not sure that path is realistic.

what you do see are environmental groups opposing making it possible to build C.C.S. anywhere in the country at all.

EZRA KLEIN: The only point I’m making here is I think this is where you see a compromise a lot of them didn’t want to make —ROBINSON MEYER: Exactly, yeah.EZRA KLEIN: — which is a decarbonization strategy that actually does extend the life cycle of a lot of fossil fuel infrastructure using carbon capture. And because they never bought onto it, they’re still using the pathway they have to try to block it. The problem is that’s part of the path that’s now been chosen. So if you block it, you just don’t decarbonize. It’s not like you get the 100 percent renewable strategy.

ROBINSON MEYER: Exactly. The bargain that will emerge from that set of actions and that set of coalitional trade-offs is we will simply keep running this, and we will not cap it.

What could be possible is that progressives and Democrats and the E.P.A. turns around and says, “Oh, that’s fine. You can do C.C.S. You just have to cap every single stationary source in the country.” Like, “You want to do C.C.S.? We totally agree. Essential. You must put CSS infrastructure on every power plant, on every factory that burns fossil fuels, on everything.”

If progressives were to do that and were to get it into the law — and there’s nothing the Supreme Court has said, by the way, that would limit progressives from doing that — the upshot would be we shut down a ton more stationary sources and a ton more petrochemical refineries and these bad facilities that groups don’t want than we would under the current plan.

what is effectively going to happen is that way more factories and power plants stay open and uncapped than would be otherwise.

EZRA KLEIN: So Republican-controlled states are just on track to get a lot more of it. So the Rocky Mountain Institute estimates that red states will get $623 billion in investments by 2030 compared to $354 billion for blue states.

why are red states getting so much more of this money?

ROBINSON MEYER: I think there’s two reasons. I think, first of all, red states have been more enthusiastic about getting the money. They’re the ones giving away the tax credits. They have a business-friendly environment. And ultimately, the way many, many of these red-state governors see it is that these are just businesses.

I think the other thing is that these states, many of them, are right-to-work states. And so they might pay their workers less. They certainly face much less risk financially from a unionization campaign in their state.

regardless of the I.R.A., that’s where manufacturing and industrial investment goes in the first place. And that’s where it’s been going for 20 years because of the set of business-friendly and local subsidies and right-to-work policies.

I think the administration would say, we want this to be a big union-led effort. We want it to go to the Great Lakes states that are our political firewall.

and it would go to red states, because that’s where private industry has been locating since the ’70s and ’80s, and it would go to the Southeast, right, and the Sunbelt, and that that wouldn’t be so bad because then you would get a dynamic where red-state senators, red-state representatives, red-state governors would want to support the transition further and would certainly not support the repeal of the I.R.A. provisions and the repeal of climate provisions, and that you’d get this kind of nice vortex of the investment goes to red states, red states feel less antagonistic toward climate policies, more investment goes to red states. Red-state governors might even begin to support environmental regulation because that basically locks in benefits and advantages to the companies located in their states already.

I think what you see is that Republicans are increasingly warming to EV investment, and it’s actually building out renewables and actually building out clean electricity generation, where you see them fighting harder.

The other way that permitting matters — and this gets into the broader reason why private investment was generally going to red states and generally going to the Sunbelt — is that the Sunbelt states — Georgia, Texas — it’s easier to be there as a company because housing costs are lower and because the cost of living is lower in those states.

it’s also partially because the Sunbelt and the Southeast, it was like the last part of the country to develop, frankly, and there’s just a ton more land around all the cities, and so you can get away with the sprawling suburban growth model in those citie

It’s just cheaper to keep building suburbs there.

EZRA KLEIN: So how are you seeing the fights over these rare-earth metals and the effort to build a safe and, if not domestic, kind of friend-shored supply chain there?

Are we going to be able to source some of these minerals from the U.S.? That process seems to be proceeding but going slowly. There are some minerals we’re not going to be able to get from the United States at all and are going to have to get from our allies and partners across the world.

The kind of open question there is what exactly is the bargain we’re going to strike with countries that have these critical minerals, and will it be fair to those countries?

it isn’t to say that I think the I.R.A. on net is going to be bad for other countries. I just think we haven’t really figured out what deal and even what mechanisms we can use across the government to strike deals with other countries to mine the minerals in those countries while being fair and just and creating the kind of economic arrangement that those countries want.

, let’s say we get the minerals. Let’s say we learn how to refine them. There is many parts of the battery and many parts of EVs and many, many subcomponents in these green systems that there’s not as strong incentive to produce in the U.S.

at the same time, there’s a ton of technology. One answer to that might be to say, OK, well, what the federal government should do is just make it illegal for any of these battery makers or any of these EV companies to work with Chinese companies, so then we’ll definitely establish this parallel supply chain. We’ll learn how to make cathodes and anodes. We’ll figure it out

The issue is that there’s technology on the frontier that only Chinese companies have, and U.S. automakers need to work with those companies in order to be able to compete with them eventually.

EZRA KLEIN: How much easier would it be to achieve the I.R.A.’s goals if America’s relationship with China was more like its relationship with Germany?

ROBINSON MEYER: It would be significantly easier, and I think we’d view this entire challenge very differently, because China, as you said, not only is a leader in renewable energy. It actually made a lot of the important technological gains over the past 15 years to reducing the cost of solar and wind. It really did play a huge role on the supply side of reducing the cost of these technologies.

If we could approach that, if China were like Germany, if China were like Japan, and we could say, “Oh, this is great. China’s just going to make all these things. Our friend, China, is just going to make all these technologies, and we’re going to import them.

So it refines 75 percent of the polysilicon that you need for solar, but the machines that do the refining, 99 percent of them are made in China. I think it would be reckless for the U.S. to kind of rely on a single country and for the world to rely on a single country to produce the technologies that we need for decarbonization and unwise, regardless of our relationship with that country.

We want to geographically diversify the supply chain more, but it would be significantly easier if we did not have to also factor into this the possibility that the US is going to need to have an entirely separate supply chain to make use of for EVs, solar panels, wind turbines, batteries potentially in the near-term future.

, what are three other books they should read?

The first book is called “The End of the World” by Peter Brannen. It’s a book that’s a history of mass extinctions, the Earth’s five mass extinctions, and, actually, why he doesn’t think we’re currently in a mass extinction or why, at least, things would need to go just as bad as they are right now for thousands and thousands of years for us to be in basically the sixth extinction.

The book’s amazing for two reasons. The first is that it is the first that really got me to understand deep time.

he explains how one kind of triggered the next one. It is also an amazing book for understanding the centrality of carbon to Earth’s geological history going as far back as, basically, we can track.

“Climate Shock” by Gernot Wagner and Marty Weitzman. It’s about the economics of climate change

Marty Weitzman, who I think, until recently, was kind of the also-ran important economist of climate change. Nordhaus was the famous economist. He was the one who got all attention. He’s the one who won the Nobel.

He focuses on risk and that climate change is specifically bad because it will damage the environment, because it will make our lives worse, but it’s really specifically bad because we don’t know how bad it will be

it imposes all these huge, high end-tail risks and that blocking those tail risks is actually the main thing we want to do with climate policy.

That is I think, in some ways, what has become the U.S. approach to climate change and, to some degree, to the underlying economic thinking that drives even the I.R.A., where we want to just cut off these high-end mega warming scenarios. And this is a fantastic explanation of that particular way of thinking and of how to apply that way of thinking to climate change and also to geoengineerin

The third book, a little controversial, is called “Shorting the Grid” by Meredith Angwin

her argument is basically that electricity markets are not the right structure to organize our electricity system, and because we have chosen markets as a structured, organized electricity system in many states, we’re giving preferential treatment to natural gas and renewables, two fuels that I think climate activists may feel very different ways about, instead of coal, which she does think we should phase out, and, really, nuclear

By making it easier for renewables and natural gas to kind of accept these side payments, we made them much more profitable and therefore encouraged people to build more of them and therefore underinvested in the forms of generation, such as nuclear, that actually make most of their money by selling electrons to the grid, where they go to people’s homes.

U.S. natural gas is far less damaging to the environment than coal. It has become so cheap that it is displacing coal in electricity generation, driving down emissions. To others, Cove Point is an environmental catastrophe. Natural gas is still a fossil fuel, and burning it releases lots of greenhouse-gas emissions, which cause climate change. Both arguments are right.

society must eliminate its carbon dependency. It cannot burn vast amounts of any fossil fuel for “decades and decades,” as Mr. Farrell hopes, unless there is a revolution in emissions capture technology. Even in the short term, U.S. emissions are rising, despite the restraint that stepped-up natural-gas burning has provided. The government must demand more change, more quickly.

One objection is that carbon pricing is not powerful enough. The European Union’s carbon pricing program has not worked well. But that is a failure of design and political will. A carbon price equal to the challenge would start high and rise higher, sending a much stronger price signal.

carbon pricing is still the best first-line policy

A high-enough carbon price would shape millions of choices, small and large, about what to buy, how to invest and how to live that would result in substantial emissions cuts. People would prioritize the easiest changes, minimizing the costs of the energy transition. With a price that steadily rose, market forces would steadily wring carbon dioxide out of the economy — without the government trying to dictate exactly how, wasting money on special-interest boondoggles.

The Intergovernmental Panel on Climate Change found last year that an average carbon price between 2030 and the end of the century of $100, $200 or even $300 per ton of carbon dioxide would result in huge greenhouse-gas emissions cuts, could restrain warming to the lowest safety threshold of 1.5 degrees Celsius and would almost certainly prevent the world from breaching the traditional warming limit of 2 degrees Celsius

Republicans never embraced the market-based idea, even though conservative economists admit its appeal, because they never accepted the need to act at all. Some environmentalists, meanwhile, are increasingly wary of carbon pricing. The Democrats’ Green New Deal, which is noncommittal on the policy, reflects the accelerating drift from the obvious.

A third objection is that carbon pricing is politically impossible, because it reveals the cost of fighting global warming in the prices people pay

Another criticism is that carbon pricing hurts the poor, who would suffer most when prices rose. But the revenue from carbon pricing could be recycled back to Americans in a progressive way, and most people would end up whole or better off.

This is a leadership challenge, not a policy challenge. More than 40 governments globally, including several states, have found the political will to embrace carbon pricing programs, which is the only option that would plausibly be bipartisan.

One objection does have merit: Though carbon pricing would spur huge change in infrastructure and power generation, that alone would not be enough. It would not stimulate all the innovation the nation needs in the climate fight, nor would it change behaviors in circumstances where the desired price signal is muted or nonexistent

Foreign aid to prevent deforestation could be among the most cost-effective climate-preserving measures. Helping other countries to replace archaic cooking stoves that produce noxious fumes would help cut emissions and improve quality of life across the developing world.

, economists know that companies that invest in research and development do not get rewarded for the full social value of their work. Others benefit from their innovations without paying. Consequently, firms do not invest in research as much as society should want

It would take only a small fraction of the revenue a carbon pricing system would produce to fund a much more ambitious clean-energy research agenda. Basic scientific research and applied research programs such as ARPA-E should be scaled up dramatically

The government must also account for the fact that not all greenhouse-gas emissions come from burning the fuels that a carbon pricing program would reach — coal, oil and gas. How would the government charge farmers for the methane their cows emit or for the greenhouse gases released when they till their soil? How about emissions from cement, ammonia and steel production? The federal government would have to tailor programs to the agricultural and industrial sectors, which might include judicious use of incentives and mandates.

only government can ensure adequate mass transit options. Local governments could help with zoning laws to encourage people to live in denser, more walkable communities. The federal government should also press automakers to steadily improve fuel efficiency.

That starts with making sure that emissions-cutting efforts at home do not have unintended consequences. If the United States puts a price on greenhouse-gas emissions, other countries would lure U.S. manufacturers with the promise of lax environmental rules. Relocated manufacturers could then export their goods to the United States. The net effect would be no benefit for the planet but fewer U.S. manufacturing jobs.

One response is a kind of tariff on goods entering the country from places with weaker carbon-dioxide policies. That would both eliminate the incentive to offshore manufacturing and encourage countries to strengthen their own rules.

Participating in the agreement would give the United States a forum — and a basis — to press other nations to reduce emissions.

Start with carbon pricing. Then fill in the gaps.

There are a lot of bad ideas out there.

The Green New Deal that some Democrats have embraced is case in point. In its most aggressive form, the plan suggests the country could reach net-zero greenhouse-gas emissions by 2030, an impossible goal

that would be more spent every three years than the total amount the country spent on World War II.

At the same time, the Democratic plan would guarantee every American “high-quality health care” and “a job with a family-sustaining wage, adequate family and medical leave, paid vacations, and retirement security.” These expensive aspirations, no matter how laudable, would do nothing to arrest greenhouse-gas emissions.

Massive social reform will not protect the climate. Marshaling every dollar to its highest benefit is the strongest plan.

the benefits are really vivid, they are really clear. Everybody agrees that the world will be better off the faster we move. And that really wasn’t the case five or 10 years ago. There was much more muddled analysis and messaging then. And I think we have to take advantage of the new unanimity and not let people fall back on the logic of status quo bias and incumbency and just think that change is expensive and difficult

david wallace-wellsMy basic feeling is that the changes that we need are all systemic. And so the things that individuals can do to make that change are primarily through the political realm, not through their individual behavior. If we want to really halt this problem and get a handle on it, it means large, large scale changes that are beyond the capacity of individuals to enact on their own.

jane coastonHow do we get our house in order? What do I as an individual or the people listening to this podcast, how do I make this happen on my level? Knowing all of that, what do I do? What do I personally need to do? Give me a thing to do, Genevieve!

If you want to learn more about personal responsibility, I recommend Jason Marks’s article in the Sierra Club magazine, “Yes, actually, individual responsibility is essential to solving the climate crisis,” and the New York Times guest essay by Auden Schendler, “Worrying About Your Carbon Footprint is Exactly What Big Oil Wants You to Do.”

david wallace-wells

I don’t know that we have to all take on a feeling of guilt for the rise of G.D.P. under neoliberalism, because I don’t know that most of us have actually even seen that money.

ultimately, the things that we need to do to really get a hold of this are way bigger than cutting your food emissions by 10 percent or 50 percent or whatever. It’s like, the three of us in this room, we can’t build an electric grid, a solar farm. We can’t make sure that there are Tesla charging stations all across the country. We can’t re-imagine land use policy or agricultural policy. We can’t put an honest price on carbon so that when you’re buying gas, you’re actually paying for the environmental damage that’s being caused or when you’re buying an airplane ticket. Those are just things that are well outside of our capacity to control

jane coastonCould you explain what climate justice means to an audience that is me?genevieve guentherBasically, it means that the global north historically has been responsible for the vast majority of carbon pollution. And the global south has been responsible for almost none of it. Since 1990, for example, the top 10 percent of earners have been responsible for 52 percent of the growth of global emissions. And the poorest, 50 percent, who largely live in the global south, have been responsible for about 7 percent of global emissions. But that hasn’t grown at all. Historically, they have contributed nothing to the exponential growth of emissions and the increased and accelerating global heating that we’re already seeing. So the idea of climate justice is that global north nations have a moral responsibility to reduce their emissions first and faster so that there is some room left in whatever carbon budget we still have for the global south to pull themselves out of poverty.

jane coastonDavid, what do you make of what Genevieve said about the messaging about good and evil there?

david wallace-wellsI would say even more importantly, we can’t set our standard at extinction. It’s not like if we survive and avoid extinction, that that’s a success. There is huge suffering between here and there. And every degree of temperature rise is going to create more suffering. And every degree we avoid can help us avoid that.

The climate crisis has begun in the United States, too. But the real violence of it is in the global south. And I would argue that the global north doesn’t see it because the news media isn’t reporting on it and because the kind of white supremacy prevents people in this country from really recognizing that this is a violence that would feel unimaginable if it happened to their children.

genevieve guentherOK, so the first part is understanding why we have to do this. And I would argue that most Americans still don’t know enough about global heating and the climate crisis.

jane coastonYeah, but and a benefit when? Because I think a lot of this messaging relies on something that, in general, people do not like, which is, you may need to do a thing or change a thing about your life for a future that we have not yet defined. From a messaging perspective, how do we message the urgency

To think about the concrete impacts, 350,000 Americans, it’s estimated, die every single year from the air pollution from the burning of fossil fuels. That is a death toll literally equal to the 2020 death toll from COVID.

Or is it going to take so long that, in fact, things are going to spiral out of control?

within the space of a few years, by simply refusing to accept their own impotence, they have literally remade the entire landscape of global climate politics. Like in the U.S., when we have Joe Biden who Sunrise gave an F to in the primary, talking about this as an existential threat, that is because the protests worked. And they worked in an incredibly short amount of time

I personally think the high consumption, and particularly the flying of people who are in the public eye, trying to communicate the urgency of the climate crisis, is incredibly destructive to building a political movement. They’re actually doing something extremely counterproductive in my interpretation. They’re reinforcing everybody’s cognitive dissonance with their behavior, which is also a form of speech. They’re communicating that they’re not willing to make transformative changes and not willing to support transformative policies, and that, in fact, you need to use fossil fuels even to do climate work. And so, for me, I feel like the people who need to worry about their carbon footprints insofar as anybody does are the 1 percent and people in the climate movement.

here are huge, huge health consequences from this pollution. It may be the case that air pollution may even be a bigger crisis than climate change. That is how dramatic these impacts are. They happen to be caused largely by the same thing so we can solve them at the same time, but we’re talking about rising rates of respiratory disease and coronary disease and cancers of all kinds and Alzheimer’s and dementia and ADHD and criminality and premature birth and low birth weight. And just every aspect of human flourishing is damaged by the pollution that is produced by the burning of fossil fuels

david wallace-wellsIt’s really, really stark, as Genevieve lays out, that it is the wealthy countries of the world and the wealthy people of the world who have engineered this crisis. So whenever we hear about the problem of India, the problem of electrifying sub-Saharan Africa, these are problems. We need to figure them out and do them clean in a way that doesn’t imperil the future of the planet. But those are only problems that we have to deal with now because of the development patterns that countries like ours and across northern Europe went through over the last few decades and centuries.

Half of all emissions in the entire history of humanity have come in the last 30 years. Now since Al Gore published his first book on warming, you know I often joke it’s since the premiere of “Friends,” which means that, actually, the people who have done the lion’s share of the damage to the planet are alive today. And it is true, of course, that the people who have been running Shell and Chevron and ExxonMobil have much more responsibility than I do or Genevieve does or Jane does. But it is also the case that all of us have benefited in significant ways from economic activity that has been powered by fossil fuels and to which we could have raised louder objections earlier.

genevieve guentherI think it’s worthwhile to point out that the vast majority of Americans are literally going to be richer once we have decarbonized, because their electricity, their heating, their transportation, and their health care costs are going to go down significantl

genevieve guentherPick one. Do it once a week, and things will change. First thing is vote. You can’t do that once a week, but vote in every election. Vote

some of the actions that you’re talking about, the individual actions, I think can be useful in terms of generating small scale political energy that can eventually sort of trickle up into politics. Leaders see that we’re making changes. They see that we’re demanding changes. They may feel more comfortable making those changes themselves.

We as a culture need to normalize that it’s actually healthy not to be happy in the face of climate change and that it doesn’t mean we’re failed Americans. It means that we’re actually human beings who are having an appropriate and ethical moral response to the suffering that is coming in the pipe for everybody, also our own children

Or you can donate to groups that are working on electoral politics directly, like the Environmental Voter Project or Stacey Abrams’s Verified Action

david wallace-wellsHonestly, the person I was talking to was the United States. I mean, that is the perspective that we have as a country. And as guilty as I feel as responsible as I feel, as I’m sure, Genevieve, and to some extent, Jane, you feel, all of us are actually behaving in ways that are imposing that kind of suffering on people elsewhere in the world. It’s almost unavoidable, given the systems that we live in today. And that is really horrifying. But I think the more clearly that we can see that, the more likely we are to be demanding real change of our leaders and the systems in which we live

david wallace-wellsWell, some of them can matter in limiting your carbon footprint. So if you don’t eat beef, if you don’t take airplanes, if you drive an electric car, you’re probably pretty far along in reducing your own carbon footprint. And that is one measure of climate responsibility, carbon responsibility

The ability to put your preferred candidates in office is a huge part of the climate fight

david wallace-wellsI think that this story is one about our responsibility towards other humans, in which collectively, human behavior has imperiled the future of the planet. I think as a result, we have to talk about it in terms of good and evil, that there are very obvious sides.

And it is borne disproportionately by Black and Brown and poor people.

genevieve guentherI actually agree with David. This is a systemic problem that is only going to be solved by governments and large corporations leading the transformation of our economies to zero-emission economies. That said, rich people across the globe have a responsibility, a personal responsibility, to reduce their discretionary emissions, to reduce their consumption, both for climate justice reasons and also simply because we need them to do it if we’re going to meet our emissions targets and halt global heating.

what is hopeful about these net zero pledges, even as they are greenwashing, is the fact that these companies feel pressure to make them at all, right? This is a sea change in politics. If they can’t actually transform, they’re going to be pushed out, and new incumbents are going to come in. And the question is, can we do this fast enough to halt global warming in time to preserve much of the habitable world?

The second piece is a kind of climate communication that shows people how this is going to affect them. Most people think of this as a crisis that’s for the global south or for the distant future or for our grandchildren’s grandchildren or whatever. And it’s up to every single communicator, as far as I’m concerned, to make it clear in really concrete embodied terms what this crisis is going to mean for the children who are alive today.

When I started writing about climate five years ago, I would not have thought that this kind of political change was at all possible. We are living through what is a genuinely unprecedented global climate awakening, which has totally changed the landscape of what is possible. And it really has made the world and the future look sunnier

famously last year, Drew Shindell, who’s an air pollution expert at Duke, testified before U.S. Congress saying that a green transition of the American energy system would entirely pay for itself through the public health benefits of cleaner air. You could put aside all of the climate impacts. You could put aside all the benefits of cheaper electricity. And just because we would be healthier as a result, even in the U.S. where air is already clean, the dollars and cents would add up and make that a very, very clear win for all of us

here’s another thing you can do. You can organize your workplace to ask your company to make greener business decisions or to lobby Congress for climate policies

once they’re in office, keep pressuring them. Call their D.C. offices. Call their local offices. Send them emails regularly

he dynamic is even more horrifying elsewhere in the world where other countries have much dirtier air than we do. Estimates are as high as 10 million people globally dying of air pollution every single year, 8.7 million of them from the burning of fossil fuels

then the third piece of that is really showing how making these changes that are required would be such a benefit to them.

that you have to live like a monk to make this work. That may have been, to some degree, true 25, 30 years ago when the alternative systems that we now see right around the corner were much farther away in the distance and much more expensive. But it just isn’t the case now that to green our economy will require an enormous burden

when we think of it simply in terms of, is the economy going to grow faster or is it going to go slower, I think we really, really miss the huge, huge public health consequences of continuing running the systems as we are running them today, and also the huge benefits we would get from getting off those systems

david wallace-wellsIn 2070, we’re in a net zero world. Nobody has a carbon footprint. So having more kids is not going to make one difference in either direction. And I think we’re still in a place where we can keep that goal in mind and fight to make that possible so that we don’t have to do things like reduce family size.

I had this interaction just before the pandemic at an event I did. I keep thinking about it. I think about it maybe every week, maybe every day, where I gave a talk about looking at how dire some of these situations could be. And afterwards, somebody came up to me who assured me that he was not a climate denier. And then he said, so really, how bad is it going to get? And I said, well, at two degrees, we’re talking about 150 million people dying of air pollution. And he said, but that’s out of 8 billion. And I said, well, yeah, I mean, I’m not talking about the total extinction of the human race here, but 150 million is 150 million. That’s 25 Holocausts. And he said, but out of 8 billion.

the true, are we going to make humans extinct, kind of futures that we were talking about as slim but real possibilities a few years ago, I think are much, much less likely today. And that is in large part the result of climate protests by people who started their activism within the last few years.

genevieve guentherAnd just say that the word “responsibility” has two different definitions, right? There’s the sense of responsibility as guilt. Who is responsible for this crime? Who has to pay the price? But then there’s responsibility as duty. Who’s going to take responsibility for cleaning up this mess?

There is a very small ask that can be made, which is just to support the people who support aggressive climate action. We’re talking about massive, immediate, or quasi immediate payback for all of the investments we’re making.

If you don’t have the time to do that, donate money. Donate money to organizations that are putting their bodies on the line. Here are some of them— Sunrise, Fridays for Future

finally, one of the most impactful things that you can do is simply talk about climate change in your social networks, especially when it feels most socially awkward and embarrassing. Because unless we continue to break the kind of conspiracy of climate silence that allows people to look away, we’re not actually going to have the kind of pressure internally and psychologically in people that will help them join the climate movemen

genevieve guentherWell, let me contextualize this for a moment. The concept of the carbon footprint is actually a legitimate concept in sustainability research. It was developed by two researchers in the 1990s

What is the 1 percent? In the United States, I would define the 1% as people making $450,000 a year and above. So it’s hard to imagine how much consumption is normalized among these people. It is not at all considered wasteful to buy a new SUV every two or three years as new models come out. It is not all considered extravagant to fly up to 20 times a year. It is not at all horrific to buy an entirely new wardrobe two or three times a year and throw it all away. In fact, this is considered a signal that you are in the rich group and that you are living your best life.

it actually has to be done right now. We don’t get another shot at this.

Do my personal actions, be they avoiding plastic straws or composting or calculating my personal carbon footprint, as oil companies seem to really want me to do, or switching light bulbs or becoming a vegetarian, in the scheme of averting climate change or mitigating climate change, do those actions really matter?

I think that there are certain actors who have played hugely disproportionate, often toxic, roles in that story, namely the fossil fuel industry and their allies in political power, not just in the U.S. but all around the world.

that’s not to say that that person is as culpable as the CEOs of ExxonMobil. Obviously, there’s a huge spectrum of culpability, but I think that a huge majority of Americans are understandably viewed by people elsewhere in the world as contributing to the problem as opposed to contributing to the solution, and that we should not dismiss that judgment because we happen to think, well, I was just doing it for myself, or I was just acting in the system in which I live. We should take seriously that judgment and try to think about what we can do to sort of make it right, so to speak.

But BP extracted this concept from academia and created a multimillion dollar campaign, trying to change the discourse of the climate crisis and make, as you said, Jane, everybody feel responsible for causing the climate crisis, but also feeling responsible for solving it by doing things like no longer driving or no longer flying or no longer eating beef or turning off lights or using plastic straws. And as David said, this is impossible. Even if every single one of us brought our personal carbon emissions down to zero, we would not halt global heating.

number two, join a campaign or an activist group. There are local chapters of groups called the Sunrise Movement and 350.org in many communities. If you’re really hardcore, you can join Extinction Rebellion

It will require an investment, but that will sort of pay for itself in the relatively short term. And so we’re now in a situation where a lot of people often think that moving into a sustainable future is going to make their lives suck. And the truth is that just isn’t the case, but that is what the companies that are profiting from the status quo would like you to think because nobody wants their lives to suck.

I think we need to really tell the climate story as a story of good and evil because these people have known for decades what their products were going to do. And not only did they keep producing and selling fossil fuels, they lied about it. They lied about what they knew. And they tried to do everything they could to capture our political system just to sustain their own wealth and power. I think that’s pretty bad. It’s criminal. It’s absolutely criminal.

some of the changes that you’re talking about, people are compelled to do because they don’t want to feel a part of the ugliness of the destruction of the planet, more than because they’re making a rational calculation about how best to use their time and what they can do that has the highest impact

But the fossil fuel industry, as part of their disinformation campaign, wants to make everyone feel helpless, feel overwhelmed, and wants to shift our attention away from the political action that has a chance of resolving the climate crisis to what can’t possibly work, which is focusing on our carbon footprint.

I just don’t think that that’s the end all, be all of it, because I do think that many people, even today, think, OK, I want the future to be stable and green and prosperous. But I don’t want to pay $1 more at the pump for a gallon of gas and may actually vote in an election on that basis

That said, reducing the discretionary emissions of the top 1 percent is actually a piece of the decarbonization puzzle. So, if the top 10 percent reduced their carbon emissions do

n to the level of the average European, which is still quite significant — eight tons a year — we would be about one-third of the way to decarbonizing our systems. So we emit as a globe about 30 gigatons of carbon dioxide a year. And this reduction in luxury consumption would reduce emissions by about 10 gigatons a year. So that is just a staggering number.

Most of the people who are listening to this podcast and nobody in this room, for sure, is responsible for causing the climate crisis. But we’re all responsible for now solving it to the best way that we can.

Greenpeace. And here are some social justice organizations — UPROSE and WE ACT. There are also two new organizations who are writing climate policy in a new way and lobbying on the Hill to get them passed. They are Climate Power and Evergreen Action.

While there is a sort of transition bump and we should have public policy that addresses it, especially for communities who are already suffering, it’s also the case that the obvious economic logic is also the obvious environmental logic here. These are no longer in tension.

for me, that answer is really exclusively through a political engagement and political activism because we really need to shake the whole infrastructure of the world. And the only people who are capable of doing that are the people who are in corridors of power in politics and the corporate worl

there is no sign of flying long-haul on an electric plane any time soon.

The answer to this is to remove carbon dioxide from the atmosphere, using “negative emissions technologies”

How can it be done? The UK is betting on bioenergy with carbon capture and storage, BECCS, where carbon is removed from the atmosphere by crops or trees as they grow. This biomass is then burned in a power station to generate electricity, and the waste carbon dioxide is pumped far underground

A second approach is to restore or enhance processes that naturally remove carbon dioxide from the atmospher

orest restoration removes carbon by storing it in trees, and soils can also take up carbon, for example, if crushed silicate rocks are spread on to them, enhancing a natural chemical process

Politicians and their advisers love them, because they can announce a target such as 1.5C while planning to exceed it, with temperatures hopefully clawed back later in the century through negative emissions.

The greater the negative emissions, the less decarbonisation is needed. Negative emissions technologies are deployed as a weapon to avoid taking serious action on climate.

Most scenarios have more than 730bn tonnes of carbon dioxide sequestered as negative emissions this century. That is equivalent to all the carbon dioxide emitted since the industrial revolution by the US, the UK, Germany and China combined. There just isn’t enough land to suck up that much carbon into new forests

using BECCS to remove this much carbon, as most scenarios assume, would require an area of new cropland larger than India, plus building a facility to store 1m tonnes of carbon a year every single day from 2025 until 2050. Negative emissions at this scale are the stuff of fantasy.

The researchers say halving emissions every decade should be complemented by equally ambitious, exponential roll-out of renewables

For example, doubling renewables in the energy sector every 5-7 years, ramping up technologies to remove carbon from the atmosphere, and rapidly reducing emissions from agriculture and deforestatio

They propose that to remain on this trajectory all sectors of the economy need decadal carbon roadmaps that follow this rule of thumb, modeled on Moore's Law.

Moore's Law states that computer processors double in power about every two years. While it is neither a natural nor legal law, this simple rule of thumb or heuristic has been described as a "golden rule" which has held for 50 years and still drives disruptive innovation

a "carbon law" offers a flexible way to think about reducing carbon emissions. It can be applied across borders and economic sectors, as well as both regional and global scales.

"Our civilization needs to reach a socio-economic tipping point soon, and this roadmap shows just how this can happen. In particular, we identify concrete steps towards full decarbonization by 2050.

no single solution will do the job, and that this deep uncertainty thus implies starting today pursuing multiple options simultaneously.

Following a "carbon law," which is based on published energy scenarios, would give the world a 75% chance of keeping Earth below 2°C above pre-industrial temperatures, the target agreed by nations in Paris in 2015

How to get there: 2020: remove fossil fuel subsidies. Put a price on carbon starting at $50 per ton rising to $400 per ton by 2050. Large-scale energy efficiency measures and large scale trials of carbon sequestration begin at 100-500MtCO2/yr.

Every law embodies a particular hypothesis about how the world works, a hope that if you pull on levers A and B, then outcomes C and D will result

Democrats hope to create an economy where the government doesn’t just help Americans buy green technologies; it also helps nurture the industries that produce that technology.

The idea is this: The era of passive, hands-off government is over. The laws embrace an approach to governing the economy that scholars call “industrial policy,” a catch-all name for a wide array of tools and tactics that all assume the government can help new domestic industries get started, grow, and reach massive scale.

If “this country used to make things,” as the saying goes, and if it wants to make things again, then the government needs to help it. And if the country believes that certain industries bestow a strategic advantage, then it needs to protect them against foreign interference.

From its founding to the 1970s, the country had an economic doctrine that was defined by its pragmatism and the willingness of its government to find new areas of growth.

It’s more like a toolbox of different approaches that act in concert to help push technologies to grow and reach commercial scale. The IRA and the two other new laws prefer four tools in particular.

“Yes, there was an ‘invisible hand,’” Stephen Cohen and Brad DeLong write in their history of the topic, Concrete Economics. “But the invisible hand was repeatedly lifted at the elbow by the government, and placed in a new position from where it could go on to perform its magic.”

That pragmatism faded in the 1980s, when industrial policy became scorned as one more instance of Big Government coming in to pick so-called winners and losers.

The two other large bills passed by this Congress—the $1 trillion bipartisan infrastructure law and the CHIPS and Science Act—make down payments on the future as well; both laws, notably, were passed by bipartisan majorities.

it is in the IRA that these general commitments become specific, and therefore transformative.

Since the 1980s, when Congress has wanted to spur technological progress, it has usually thrown money exclusively at R&D. We have had a science policy, not an industrial policy

inextricable from that turn is Washington’s consuming anxiety over China’s rise—and China has embraced industrial policy.

although not a single Republican voted for the IRA, its wager is not especially partisan or even ideological.

the demonstration project. A demonstration project helps a technology that has previously existed only in the lab get out in the real world for the first time

supply-push policies. As the name suggests, these tools “push” on the supply side of an industry by underwriting new factories or assuring that those factories have access to cheap inputs to make things.

demand-pull policies, which create a market for whatever is coming out of those new factories. The government can “pull” on demand by buying those products itself or by subsidizing them for consumers.

protective policies, meant to insulate industries—especially new ones that are still growing—from foreign interference

Although both parties have moved to embrace industrial policy, Democrats are clearly ahead of their Republican colleagues. You can see it in their policy: While the bipartisan infrastructure law sets up lots of demonstration projects, and the CHIPS Act adopts some supply-push and protectionist theory, only the IRA uses all four tools.

In order to stop climate change, experts believe, the United States must do three things: clean up its power grid, replacing coal and gas power plants with zero-carbon sources; electrify everything it can, swapping fossil-fueled vehicles and boilers with electric vehicles and heat pumps; and mop up the rest, mitigating carbon pollution from impossible-to-electrify industrial activities. The IRA aims to nurture every industry needed to realize that vision.

Hydrogen and carbon removal are going to benefit from nearly every tool the government has. The bipartisan infrastructure law will spend more than $11 billion on hydrogen and carbon-removal “hubs,” huge demonstration projects

These hubs will also foster geographic concentration, the economic idea that when you put lots of people working on the same problem near one another, they solve it faster. You can see such clustering at work in San Francisco’s tech industry, and also in China, which now creates hubs for virtually every activity that it wants to dominate globally—even soccer.

Then the IRA will take over and deploy some good ol’ supply push and demand pull. It includes new programs to underwrite new hydrogen factories; on the demand side, a powerful new tax credit will pay companies for every kilogram of low-carbon hydrogen that they produce

Another tax credit will boost the demand of carbon removal by paying firms a $180 bounty for trapping a ton of carbon dioxide and pumping it undergroun

Today, not only does China make most batteries worldwide; it alone makes the tools that make the batteries, Nathan Iyer, an analyst at RMI, a nonpartisan energy think tank, told me. This extreme geographic concentration—which afflicts not only the battery industry but also the solar-panel industry—could slow down the energy transition and make it more expensive

the new tax credit is also supply-minded, arguably even protectionist. Under the new scheme, very few electric cars and trucks will immediately qualify for that full $7,500 subsidy; it will go only toward vehicles whose batteries are primarily made in North America and where a certain percentage of minerals are mined and processed in the U.S. or one of its allies. Will these policies accelerate the shift to EVs? Well, no, not immediately. But the idea is that by boosting domestic production of EVs, batteries will become cheaper and more abundant—and the U.S. will avoid subsidizing one of China’s growth industries.

Right now, next to no solar panels are made in the U.S., even though the technology was invented here. The IRA endeavors to change that by—you guessed it—a mix of supply-push, demand-pull, and protectionist policies. Under the law, the government will underwrite new factories to make every subcomponent of the solar supply chain; then it will pay those factories for every item that they produce

“It’s realistic that within four to five years, [U.S. solar manufacturers] could completely meet domestic demand for solar,” Scott Moskowitz, the head of public affairs for the solar manufacturer Q CELLS, told me.

In each of these industries, you’ll notice that the government isn’t only subsidizing factories; it is actually paying them to operate. That choice, which is central to the IRA’s approach, is “really defending against the mistakes of the 2009 bill,” Iyer told me. In its stimulus bill passed during the Great Recession, the Obama administration tried to do green industrial policy, underwriting new solar-panel factories across the country. But then Chinese firms began exporting cheap solar panels by the millions, saturating domestic demand and leaving those sparkly new factories idle

So many other industries will also be touched by these laws. There’s a new program to nurture a low-carbon aviation-fuel industry in the U.S. (Long-distance jet travel is one of those climate problems that nobody knows how to solve yet.)

the revelation of the IRA is that decarbonizing the United States may require re-industrializing it. A net-zero America may have more refineries, more factories, and more goods production than a fossil-fueled America—while also having cheaper cars, healthier air, and fewer natural disasters. And once the U.S. gets there, then it can keep going: It can set an example for the world that a populous, affluent country can reduce its emissions while enjoying all the trappings of modernity,

There are a slew of policies meant to grow and decarbonize the U.S. industrial sector; every tax credit pays out a bonus if you use U.S.-made steel, cement, or concrete. “You would need thousands and thousands of words to capture the industries that will be transformed by this,” Josh Freed, the climate and energy leader at Third Way, a center-left think tank, told me.

Five EVs were sold in China last year for every one EV sold in the United States; that larger domestic market will provide a significant economy of scale when Chinese EV makers begin exporting their cars abroad. For that reason and others, many people in China are “deeply skeptical” that the U.S. can catch up with its lead,

We are about to have a huge new set of vested interests who want the economy to be clean and benefit from that. We’ve literally never had that before,” Freed told me.

“This is going to change everything,” he said

that is the IRA’s biggest idea, its biggest hypothesis: that America can improve its standard of living and preserve its global preeminence while ruthlessly eliminating carbon pollution; that climate change, actually, doesn’t change everything, and that in fact it can be addressed by changing as little as possible.

This hypothesis has already proved itself out in one important way, which is that the IRA passed, and the previous 30 years of climate proposals did not. Now comes the real test.

Over the past 10 years, governments and private investors have collectively spent $2 trillion on infrastructure to draw electricity from the wind and the sun,

Capacity from renewable sources has grown by leaps and bounds, outpacing growth from all other sources — including coal, natural gas and nuclear power — in recent years. Solar and wind capacity installed in 2015 was more than 10 times what the International Energy Agency had forecast a decade before.

Still, except for very limited exceptions, all this wind and sun has not brought about much decarbonization. Indeed, it has not added much clean power to the grid.

“We will need twice as much investment over a sustained period of time to get anywhere close to achieving 2 degrees,”

Integrating renewable sources requires vast investments in electricity transmission — to move power from intermittently windy and sunny places to places where power is consumed. It requires maintaining a backstop of idle plants that burn fossil fuel, for the times when there is no wind or sun to be had. It requires investing in power-storage systems at a large scale.

These costs will ultimately be reflected in power prices. One concern is that by raising the retail cost of electricity they will discourage electrification, encouraging consumers to rely on alternative energy sources like gas — and pushing CO2 emissions up.

Another concern is that they will drive wholesale energy prices down too far. Because they produce the most energy when the sun is up and the wind is blowing, renewable generators can flood the grid at critical times of the day, slashing the price of power. This not only threatens the solvency of nuclear reactors, which cannot shut down on a dime and must therefore pay for the grid to accept their power, but also reduces the return on additional investment in renewables.

there is some evidence that among investors, at least, the excitement may be waning. After half a decade of sustained increases, investment in solar and wind energy has been fairly flat since 2010, at around $250 billion per year. While that is a lot of money, it is nowhere near enough.

Environmental Progress performed an analysis of the evolution of the carbon intensity of energy in 68 countries since 1965. It found no correlation between the additions of solar and wind power and the carbon intensity of energy: Despite additions of renewable capacity, carbon intensity remained flat.

I would suggest that the challenge is not just to raise more money. Building a zero-carbon energy system requires broader thinking about the technological mix.

I had other doubts, too. It seemed hubristic, or worse, to make multitrillion-dollar policy bets based on computer models trying to forecast climate patterns decades into the future. Climate activists kept promoting policies based on technologies that were either far from mature (solar energy) or sometimes actively harmful (biofuels).

Expensive efforts to curb greenhouse gas emissions in Europe and North America seemed particularly fruitless when China, India and other developing countries weren’t about to curb their own appetite for fossil fuels

just how fast is Greenland’s ice melting right now? Is this an emergency for our time, or is it a problem for the future?

His pitch was simple: The coastline we have taken for granted for thousands of years of human history changed rapidly in the past on account of natural forces — and would soon be changing rapidly and disastrously by man-made ones. A trip to Greenland, which holds one-eighth of the world’s ice on land (most of the rest is in Antarctica) would show me just how drastic those changes have been. Would I join him?
