Climate and Clean Air Coalition
UNEP, in partnership with over 60 countries and organizations, is working to phase down the use of HFCs and other substances known as short-lived climate pollutants, including black carbon or ‘soot’ and methane, under the Climate and Clean Air Coalition (CCAC).
The voluntary coalition – founded in 2012 – is promoting rapid reductions in short-lived climate pollutants to tackle air pollution, improve human health and agriculture, and provide near-term climate benefits.
Under a business-as-usual scenario, according to UNEP, by 2050, HFCs could be responsible for emissions equivalent to 3.5 to 8.8 Gigatonnes (Gt) of CO₂. This is equivalent to the total current annual carbon emissions from transport, estimated at around 6-7 Gt.
The coalition states that actions on short-term climate pollutants need to be complemented by deep and rapid cuts in CO₂ emissions if the global average temperature increase over the 21st Century is to be held below 2°C.
Among its many activities, the CCAC is working with 10 major cities including Rio de Janeiro, Lagos, Stockholm, Accra, and New York to accelerate methane reductions from landfills and black carbon or ‘soot’ from burning wastes.
