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

Green Car Congress

Geographical distributions of global BC emissions from motor vehicles in 1976 (A) and 2006 (B). Country-based mean values are shown for 1976 and 1° × 1° resolution was used for 2006. Black carbon is a key short-lived climate change forcer ( earlier post ) and motor vehicles are important sources of BC in the environment.
