- The Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants (CCAC) was launched by the United Nations Environment Programme (UNEP) and six countries—Bangladesh, Canada, Ghana, Mexico, Sweden and the United States—on 16 February 2012.
- The CCAC aims to catalyze rapid reductions in short-lived climate pollutants to protect human health, agriculture and the environment.
- To date, more than $47 million has been pledged to the Climate and Clean Air Coalition from Canada, Denmark, the European Commission, Germany, Japan, the Netherlands, Norway, Sweden, and the United States.
- The program is managed out of the United Nations Environmental Programme through a Secretariat in Paris, France.
- Short-lived climate pollutants (SLCPs) are agents that have relatively short lifetime in the atmosphere – a few days to a few decades – and a warming influence on climate.
- The main short-lived climate pollutants are black carbon, methane and tropospheric ozone, which are the most important contributors to the human enhancement of the global greenhouse effect after CO2.
- These short-lived climate pollutants are also dangerous air pollutants, with various detrimental impacts on human health, agriculture and ecosystems.
- Other short-lived climate pollutants include some hydrofluorocarbons (HFCs).
- While HFCs are currently present in small quantity in the atmosphere, their contribution to climate forcing is projected to climb to as much as 19% of global CO2 emissions by 2050.
