A committee of the International Civil Aviation Organization has proposed standards for aircraft carbon dioxide emissions. "When fully implemented, the standards are expected to reduce carbon emissions more than 650 million tons between 2020 and 2040, equivalent to removing over 140 million cars from the road for a year," the White House said in a fact sheet

Recent studies show that many of the world's savannas, including famed southern African landscapes, are experiencing significant change as rising levels of carbon dioxide in the atmosphere favor the growth of trees over grasslands.

The EU is considering placing limits on carbon dioxide emissions from commercial trucks, which account for about 25% of the region's road emissions.

Ocean acidification is set to cost us $1 trillion by 2100 as it eats away at our tropical coral reefs. The world's oceans have seen a 26 per cent increase in acidity - a result of the oceans absorbing about a quarter of our carbon dioxide emissions.

Revised government figures in Japan showed that greenhouse gas emissions were the second-highest on record for the year ended March 2014, with a total of 1.552 billion tons of carbon dioxide emissions. The record emissions level was set in 2007 at 1.556 billion tons. Japan's 48 nuclear reactors provided 26% of the country's electricity in the past, but all have been shut down since September 2013

NRG Energy announced new long-term sustainability targets, which include slashing carbon-dioxide emissions from 2014 levels 50 percent by 2030 and 90 percent by 2050.

The Obama administration's rule leans heavily on renewable energy to meet its goal to reduce carbon dioxide emissions by 32 percent by 2030, which is an increase of 2 percentage points from the draft it released in the summer of 2014. While states have two additional years until they must begin cutting emissions - 2022 instead of 2020 - they are expected to start devising ways to improve their environments, which will focus on shifting to cleaner burning fuels and away from carbon-heavy ones. "The trend we are on will get us there," says Rob Gramlich, senior vice president for government affairs at the American Wind Energy Association, in a phone interview. "As the nation moves from coal to gas, and as it adds more wind, solar and energy efficiency, we will reach that 32 percent target."

The Obama administration's Clean Power Plan rule will require states to begin cutting carbon emissions by 2022. "The trend we are on will get us there. As the nation moves from coal to gas, and as it adds more wind, solar and energy efficiency, we will reach that 32% target," said Rob Gramlich of the American Wind Energy Association. To comply, states can choose among options including boosting renewables, improving heat rates for coal-fired steam generators, and using more nuclear energy and lower-emitting natural gas.

Norway is pioneering the use of captured carbon emissions to grow an algal soup that can be used as food for farmed fish, helping to reduce overfishing of the wild krill upon which fish farms more typically rely.

Levels of CO2 in the atmosphere have surged past an important threshold and may not dip below it for "many generations." The 400 parts per million benchmark was broken globally for the first time in recorded history in 2015. But according to the World Meteorological Organisation (WMO), 2016 will likely be the first full year to exceed the mark.

Carbon dioxide, a greenhouse gas, is present at 400 parts per million for the first time ever -- a level that's 44% greater than CO2 levels prior to the Industrial Revolution, says a World Meteorological Organization report. Improvements in the near future could reduce CO2 levels by the 2060s, says WMO Secretary-General Petteri Taalas.

With carbon dioxide emissions continuing to rise, an increasing number of experts believe major technological breakthroughs - such as CO2 air capture - will be necessary to slow global warming. But without the societal will to decarbonize, even the best technologies won't be enough.

Researchers in Iceland found a new way of tackling climate change by pumping carbon dioxide underground and turning it into stone.

Global carbon dioxide emissions were flat for the second consecutive year in 2015 due, in part, to renewables, according to the International Energy Agency. The report said that renewables accounted for about 90% new installed capacity last year, and wind represented at least half of that total. Meanwhile, the world's economy jumped about 3% last year, "offering further evidence that the link between economic growth and emissions growth is weakening," said the report.

the Chicago-based aviation giant reported that it is stepping up efforts to expand the use of sustainable aviation biofuel by seeking U.S. Federal Aviation Administration approval for its aircraft to fly on "green diesel." The proposed new source of aviation biofuel emits at least half the lifecycle carbon dioxide as traditional petroleum-based jet fuel, according to Boeing.

Greenhouse gas emissions in the US totaled 6,501,000 million metric tons of carbon dioxide equivalent in 2012, a 3.3 percent reduction from the previous year, according to an annual draft report by the EPA.

Geoengineering technologies such as injecting sulfur into the atmosphere to offset carbon dioxide will begin to seem less like science fiction and more like a reasonable solution, argues David Keith of Harvard Kennedy School. Not everyone's convinced that's a good idea, though. "Solar climate engineering is a flawed idea seeking an illusory solution to the wrong problem," counters Mike Hulme of King's College London.

NEW YORK - Touted as the world's largest gathering ever on climate change, this week's U.N. Climate Summit will be as much about business as politics. Major companies, including Big Oil, will make pledges to help fight global warming by cutting their heat-trapping carbon dioxide emissions, protecting the world's forests and reducing methane leakage from fossil fuel production.

President Barack Obama is pushing American companies to abandon the use of a chemical coolant called R-134a in refrigerators, air conditioning systems and other industrial applications. R-134a is in a class of chemicals that can be up to 10,000 times as powerful a greenhouse gas per ounce as carbon dioxide.

The Dow Chemical Company today announced new sustainability goals, to be accomplished by 2025, which include creating products that offset three times more carbon dioxide than they emit throughout their life cycle and delivering $1 billion in cost savings or new cash flow by valuing nature in business decisions.

IKEA, the world's leading home furnishings retailer, today announced it had officially plugged-in Kansas' largest rooftop solar array, atop the recently opened IKEA Merriam. The 92,000-square-foot solar array consists of a 730.17-kW DC system, comprised of 2,394 panels, and will produce approximately 986,800 kWh of electricity annually for the store, the equivalent of reducing 680 tons of carbon dioxide (CO2) - equal to the emissions of 143 cars or providing electricity for 94 homes yearly (calculating clean energy equivalents at www.epa.gov/cleanenergy/energy-resources/calculator.html).

Carnegie has been on a seven-year journey to create the world's first bio-based interior textile that doesn't compromise performance, value or aesthetics.
