It was launched by the United Nations Environment Programme (UNEP) and 6 countries — Bangladesh, Canada, Ghana, Mexico, Sweden, and the United States. The CCAC aims to catalyze rapid reductions in short-lived climate pollutants to protect human health, agriculture and the environment.

                Short-lived climate pollutants are powerful climate forcers that remain in the atmosphere for a much shorter period of time than carbon dioxide (CO2), yet their potential to warm the atmosphere can be many times greater. Their effects:

  • Every year, nearly 7 million people die prematurely from the effects of indoor and outdoor air pollution. Short-lived climate pollutants are largely to blame.
  • Global relative yield losses due to tropospheric ozone exposure are up to 12% for wheat, 16% for soybean, 4% for rice, and 5% for maize.

The short-lived climate pollutants

  1. a) Black carbon – Few days
  2. b) Methane -12 years
  3. c) Tropospheric ozone – few days
  4. d) hydrofluorocarbons(HFC) -15 years

are the most important contributors to the man-made global greenhouse effect after carbon dioxide, responsible for up to 45% of current global warming.
