Study shows significant reductions in real-world heavy-duty diesel emissions from 2010 regulations

Green Car Congress

New research from North Carolina State University found that federal requirements governing diesel engines of MY 2010 tractor trailer trucks have resulted in major cuts in real world emissions of particulate matter (PM) and nitrogen oxides (NO x ). grams of PM per gallon of fuel used. The PM emissions were 95% lower.
