One of the cornerstones of the early modern environmental movement, the Clean Air Act is now forty years old.  This brief article reviews events around the 40th anniversary and discusses controversial extensions to control carbon dioxide emissions.

Recently, a politician who may take a role in our energy committe made comments against the clean air act because it shut down coal mines in the United States that couldn't meet its standards. Demand for coal on a global scale still exists, however, and now China has pollution akin to that in our industrial era. When the U.S. makes laws that help make economic actions "fair", "green", "safe", or otherwise it makes the market function better according to our values. But when other nations don't have those same regulations, business moves out, and we ship things like our waste and pollution to the third world. This video highlights a means of solving that problem. While the speaker addresses common concerns, I'm not convinced. I think he's pretty optimistic all around. How does one convince nations operating for their own good to impose limitations on themselves that might slow their growth? Easy for us to sacrifice some growth for environmental health, but a higher standard of material living matters more in impoverished areas - the conception is that taking care of environmental issues, or social issues, is a luxury derived from wealth. I really don't see a solution yet - I like what the speaker is doing, but I'm skeptical about its reliability. The store price of a good remains, I think, most people's measure of a succesful buy. Is a culture shift required to change that? More information? I'd certainly start with the latter, for the sake of doing something...

We all have heard the phrase "job-killing" applied to environmental regulations, and many may roll their eyes. But how exactly does one assess benefits and costs of regulations, and what sort of time/space frame will various interests allow in calculating benefits/costs? This takeoff on recent Obama decisions suggests some complexities.
