An Analysis of Black Carbon

Mitigation as a Response to Climate Change

Much attention has been given to mitigation policies designed to limit the emissions of carbon
dioxide (CO2) and other greenhouse gases (GHGs) that contribute to atmospheric warming.

However, it is generally agreed that as much as 40% of current net warming (10-20% of gross
warming) is attributable to black carbon. Because of its large effect on radiative forcing and
relatively short residence time in the atmosphere, black carbon presents some unique opportunities for postponing the effects of climate change.
