2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. For a number of the most important pollutants, levels were substantially lower than required by regulations. All the engines were equipped with after-treatment devices to reduce the emissions of particulate matter as well as oxides of nitrogen.

The total estimated funding for this competitive opportunity for FY 2009/2010 is approximately $64 million, including all non-tribal and tribal awards. Reducing emissions from diesel engines remains one of the most important air quality challenges facing the country, according to the EPA.

But rather than giving into despair, some engineers, policymakers, and activists are pursuing a novel strategy. There is an exception to that in the category of what they call super pollutants, the very powerful but shorter-lived gases and chemicals that come from things like fertilizer production, methane. They also mix with clouds.
