Measures Urged to Cut Short-Lived Climate Pollutants



To produce significant near-term climate benefits, the Obama administration should take a series of actions under existing authorities to reduce greenhouse gases that have relatively short atmospheric lifetimes of weeks to a few decades, according to a 12 March study by the nonprofit Center for Climate and Energy Solutions (C2ES). The report, “Domestic Policies to Reduce the Near-Term Risks of Climate Change,” notes that recent estimates suggest that about 30–40% of warming experienced to date can be attributed to these short-lived pollutants, which include black carbon, methane, and hydrofluorocarbons (HFCs).
