Fewer Fumes from Trucks and Buses — Wellness Wire

We all know what it smells like to be stuck behind a big diesel truck or to sit on an idling bus that runs on diesel. Not good, and given that diesel fumes have been tied to cancer, especially not good. There is very good news on this front, however, and that is that the new heavy-duty diesel engines of trucks and buses are now emitting 90 percent fewer toxic fumes, far surpassing the emission reductions required by the U.S. Environmental Protection Agency in 2001. Through rigorous emission tests, key pollutants have significantly dropped in releases from these newer green engines, engines which power virtually every large truck and bus sold in the US since January 2007. Key pollutants include emissions of particulate matter and nitrogen oxides.
