The Center for Climate and Energy Solutions produced a report on short-lived climate pollutants.
Short-lived climate pollutants (SLCPs), also referred to as “near-term climate forcers” by the Intergovernmental Panel on Climate Change, are greenhouse gases and other climate pollutants that have relatively short atmospheric lifetimes compared to carbon dioxide
The main SLCPs are black carbon, tropospheric ozone, and hydrofluorocarbons.
Per molecule in the atmosphere, SLCPs have a stronger warming effect than carbon dioxide, so reducing these pollutants is beneficial to reduce near-term warming, and can be very cost-effective. Actions taken in the immediate future to address them could slow the planet’s warming by about a half a degree by 2050.
Some SLCPs are also air pollutants and can be harmful to human health, so reducing them can save lives and increase public health.
