A little more info: What the EPA actually did was release two different items, a Proposed Endangerment Finding and a Proposed Cause or Contribute Finding. The Endangerment Finding basically says that certain greenhouse gases (carbon dioxide, nitrous oxide, sulfur hexafluoride, perfluorocarbons, hydrofluorocarbons, and methane) pose a danger to public health or welfare. The Cause or Contribute Finding basically says that automobile exhaust emissions contribute to the amount of these gases present in the atmosphere. These findings are still in the preliminary public comment phase. They could eventually be used as the basis for increased regulation on the amount of these gases that are emitted from automobiles, as well as other sources (industrial facilities and processes, etc.). This would mean stricter emissions standards for car engines, power plants, factory smokestacks, and so on and so forth. As stated in the article, this is probably going to stimulate discussion of a legislatively introduced "Cap and Trade" emissions-trading system, since if emissions are going to be regulated, there are a lot of people who would rather that the regulation be instituted through new legislation rather than the expansion of existing regulatory regimes to include the gases in question.

Thoughts?
