Study suggests focusing on cold starts in gasoline cars as target for emissions reduction

Green Car Congress

A new study suggests that focusing on a gasoline-fueled vehicle’s cold start is the best target for future design changes to reduce emissions of criteria pollutants. The researchers are presenting their work today at the 252 nd National Meeting & Exposition of the American Chemical Society (ACS) in Philadelphia.

CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. UC stands for uncontrolled charging and CC stands for controlled charging.

Study: US counties with higher PM2.5 concentrations have more stroke deaths

Green Car Congress

Analyzing health data and pollution monitoring information from 1,561 counties across the United States between 2005 and 2010, researchers found the yearly average for fine air pollution ranged from 7.2 The higher the poverty rate and fewer health providers in a county, the greater the health impact of high pollution.
