U.S. carbon dioxide limits touted by EPA as economically wise

The U.S. Environmental Protection Agency officially unveiled the Obama administration’s plan Monday to cut greenhouse gases 30 per cent by 2030, stressing what it says will be the economic benefits of its "clean-air revolution."

Under the plan, carbon emissions would be reduced 30 per cent by 2030, compared to 2005 levels, one of the most significant actions to address global warming in U.S. history.
