The Climate and Clean Air Coalition is a voluntary partnership of governments, intergovernmental organizations, businesses, scientific institutions and civil society organizations committed to protecting the climate and improving air quality through actions to reduce short-lived climate pollutants. These pollutants, which include methane, black carbon, tropospheric ozone, and hydrofluorocarbons (HFCs), are powerful climate forcers. Some are also dangerous air pollutants that significantly contribute to premature death and chronic illness globally. However, because of their short lifespan in the atmosphere (from weeks to decades), actions to reduce them provide quick results for air quality, the climate, and development. The Coalition has 11 initiatives working to raise awareness, mobilize resources and lead transformative actions in key sectors. Coalition measures to reduce short-lived climate pollutants can directly prevent up to 2.4 million premature deaths a year and help avoid up to half a degree Celsius of additional warming by 2050. These actions must go hand in hand with deep and persistent cuts to carbon dioxide and other long-lived greenhouse gases in order to achieve the goal of the Paris Agreement and keep global warming to 1.5 degrees Celsius.
