Soot: Harming People and Making Global Warming Worse

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.
