Short-lived climate pollutants

Short-lived climate pollutants include black carbon, tropospheric ozone, methane, and hydrofluorocarbons (HFCs).  Because these pollutants have atmospheric lifetimes of only days to a decade and a half, they are referred to as short-lived climate pollutants (SLCPs), compared to CO2 which can persist in the atmosphere for millenia.  Reducing SLCPs is critical for slowing the rate of climate change over the next several decades and for protecting the people and regions most vulnerable to near-term climate impacts. Cutting SLCPs can reduce the current rate of global warming by almost half, the rate of warming in the Arctic by two-thirds, and the Hindu Kush-Kimalaya region by half for the next 30 or more years while avoiding up to 4.7 million premature deaths each year from outdoor air pollution and up to 1.6 million a year from indoor pollution.
