Comprehensive assessment concludes black carbon second-most important human emission in warming climate

Green Car Congress

A comprehensive assessment of black-carbon climate forcing accepted for publication in the Journal of Geophysical Research: Atmospheres estimates that black carbon, with a total climate forcing of +1.1?W?m m -2 , is the second-most important human emission in terms of its climate-forcing in the present-day atmosphere.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change. —“Revised Proposed Short-Lived Climate Pollutant Reduction Strategy”.
