The Environmental Protection Agency(EPA) has recently determined that greenhouse gasses(GHG) pose a danger to public health and welfare. This weeks announcement by the EPA enables the agency to put the Clean Air Act into action. The act defines the responsibility of the EPA as protecting and improving the nations air quality.  There is a 60 day public comment period which will be documented in the federal registrar.   Once the public comment period closes, the EPA will be required to take some sort of action.

In addition, the American Clean Energy and Security Act of 2009, is being reviewed in the house and hopefully will gain the traction needed to pass as the nation’s first commitment to reduce its GHG emissions.  The bill calls for reducing greenhouse gas emissions 20% below 2005 levels by 2020, 42% by 2030, and 83% by 2050. If the EPA were to enact this legislation, it would most likely address emissions from automobiles, power plants, and major industrial sources.
