Introduction Climate and Clean Air Coalition and Short Lived Climate Pollutants


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 (a major component of soot and is produced by incomplete combustion of fossil fuel and biomass.)
• methane
• hydrofluorocarbons (HFCs) (man-made greenhouse gases used in air conditioning, refrigeration, solvents, foam blowing agents, and aerosols)
• tropospheric (ground level) ozone

SLCPs 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.

While 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.

The Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants (CCAC) was initiated in 17 Feb 2012 by the
governments of Bangladesh, Canada, Ghana, Mexico, Sweden and the United States and the United Nations Environment
Programme (UNEP). It was formed to treat these pollutants as a collective challenge. Together, they have formed an
initiative to support fast action and make a difference on several fronts at once: public health, food and energy
security and climate. The Coalition is open to countries and non-state actors that are committed to taking action on
short lived climate pollutants, and wish to join in this global effort.

The Coalition's objectives are to address short lived climate pollutants by:

1. Raising awareness of short lived climate pollutant impacts and mitigation strategies;
2. Enhancing and developing new national and regional actions, including by identifying and overcoming barriers, enhancing capacity, and mobilizing support;
3. Promoting best practices and showcasing successful efforts; and
4. Improving scientific understanding of short lived climate pollutant impacts and mitigation strategies.
