As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.

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.
Cars That Think

But rather than giving into despair, some engineers, policymakers, and activists are pursuing a novel strategy. In the stratosphere, in particular, they’re concerned about the health of the ozone layer and also how this might trap heat in the stratosphere in ways that changes the way that the atmosphere works.
