EPA Weighs Regional, Sector-Specific Frameworks To Cut Black Carbon

摘要

EPA is weighing several possible regulatory frameworks for reducing short-lived climate "forcers" such as black carbon, ozone and methane, including pursuing emission cuts on a regional basis, or developing sector-specific plans that could set new rules to target sources of the climate forcers such as diesel engines and biomass burning.rnEPA is seeking expert advice on approaches to reducing climate forcers - greenhouse gases (GHGs) that stay in the atmosphere for only days or weeks but have significant impacts on global warming - and that input could influence EPA's eventual regulatory options, which could include traditional Clean Air Act standards and emission limits.
