Soot, also known as black carbon, is the second-leading cause of global warming after carbon dioxide, and it's totally preventable. We already have the technology to avoid producing it; it's just a matter of using it.
We need tighter standards on diesel fuel at home, and we need to finance technology transfer abroad. Tell the Obama administration that reducing black carbon now will buy precious time for the Arctic, and improve public health.

Quick action to cut black carbon can slow Arctic melting, fight global warming and save lives. We must urge the U.S. to take action now to reduce black carbon emissions at home and abroad!
