EPA To Propose Greenhouse Gas Regulation Under Clean Air Act

WASHINGTON – The Environmental Protection Agency has concluded that carbon dioxide and five other greenhouse gases are a danger to public health and welfare. It is the first step to regulating pollution linked to climate change.

Congressional sources told The Associated Press that EPA will announce its proposed finding Friday and begin a comment period before issuing a final ruling. The EPA also will say tailpipe emissions from motor vehicles contribute to climate change. The officials spoke on condition of anonymity because the finding hasn't been announced.
