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.
