EPA Sets Thresholds for Greenhouse Gas, But Shields Small Businesses and Farms
In April 2010, EPA set the first national GHG tailpipe standards for passenger cars and light trucks. When GHG emissions limits for these vehicles go into effect in January 2011, EPA is also required to address GHG emissions from stationary sources under the Clean Air Act’s permitting programs, which it is doing in the plan outlined today.
The final rule addresses a group of six greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).
EPA issued a proposed rule in October 2009 and held a 60-day public comment period. The agency received about 450,000 comments, which were carefully reviewed and considered during the development of this final rule.
