Air pollution regulations over last decade in Chinese city has halved health costs

Green Car Congress

As a result, concentrations of particulate matter (PM 10 ) declined by more than half, from 196 µg/m 3 in 2001 to 89 µg/m 3 in 2010, as measured at eight sites throughout the city. Our results suggest that the air quality improvement from 2001 to 2010 resulted in substantial health benefits. billion Yuan, or approximately $621 million.

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles. A subsequent emission inventory for Asia estimated total BC emissions from on-road vehicles in this region alone to be 294 and 446 Gg in 2001 and 2006, respectively. Credit: ACS, Wang et al.
