Short-lived climate pollutants such as soot, methane and hydroflurorocarbons (HFCs) account for 30 to 40 percent of global warming to date. Targeted efforts to reduce these emissions can slow the pace of global warming and moderate climate impacts already underway, including the melting of sea ice and glaciers. By reducing local air pollution, such measures would also produce substantial public health benefits and reduce crop losses, particularly in developing countries. The factsheet outlines ways to further reduce U.S. emissions of these short-lived pollutants.
