Regulation of Vessels, Aircraft and Non-Road Vehicles
In 2007 and 2008, the Attorney General filed petitions with EPA requesting that it adopt regulations under the Clean Air Act controlling the greenhouse gas emissions from ocean-going vessels, aircraft, and non-road vehicles and engines (such as construction and farm machinery, mining equipment, lawn and garden equipment, and others). Together, these sources emit large amounts of harmful particulate matter and as much greenhouse gas as 270 million cars – more than the entire number of registered vehicles in the United States. Ocean-going vessels are responsible for 2-3% of worldwide greenhouse gas emissions. Aircraft contribute 3% of the United States carbon dioxide emissions and 12% of our transportation sector emissions. Non-road vehicles and engines emitted 220 million tons of carbon dioxide in 2007.

Because the Bush Administration EPA failed to respond to any of these petitions or otherwise take any action to regulate greenhouse gases from these sources, the Attorney General and other states sent a formal notification to EPA that it would sue EPA for unreasonable delay if it did not act on the petitions.
