Black Carbon and other Short-Lived Climate Pollutants

Short lived climate pollutants (SLCPs) are responsible for 40 to 45% of global warming caused by humans. They include black carbon, methane, tropospheric ozone, and many hydrofluorocarbons (HFCs).

These substances have a strong warming effect but a relatively short lifetime in the atmosphere – from a few days to a few decades.  

Their short lifetime means that if emissions are reduced, their atmospheric concentrations will decrease in a matter of weeks to years, effectively allowing us to slow down global warming in the next few decades. This, combined with deep and persistent cuts in CO2 and other long-lived greenhouse gases, is necessary to stabilize global temperature rise through 2100 and beyond. 

GRID-Arendal has developed a series of visual pages and an outreach booklet for UNEP´s Division of Technology, Industry and Economics, to help raise awareness and facilitate decision-making. A presentation has also been developed for the UNEP Regional Office of North America on the sources and impacts of SLCPs in the Arctic, with a special focus on the situation and well-being of Indigenous Peoples.
