Short-Lived Climate Pollutants

CO2 emissions pose the greatest long-term threat to our global climate, and reducing these emissions must form the core of any long-term climate mitigation strategy. But given the current pace of global warming and the risk of irreversible changes, we can and must take immediate steps to cool the planet

CATF's short-lived climate pollutant initiatives are aimed at reducing pollutants that will have the greatest impact in warming the planet over the near term and offer the most promising targets for immediate cleanup. These efforts target two of the leading short-lived climate pollutants, methane and black carbon (BC). Because these gases and aerosols have a much shorter atmospheric lifespan than CO2, significant cuts in their emissions will yield much faster reductions in planetary warming, as compared to reductions in CO2. This is particularly the case in snow- and ice-covered regions, including the Arctic where warming is occurring at twice the rate of the rest of the world and mountain regions. By targeting these short-lived pollutants we can also improve air quality and public health because black carbon is a key constituent of deadly fine particulate matter and methane increases ozone smog levels globally.

CATF is active in a number of different venues internationally, supporting scientific research, promoting policy initiatives, encouraging financial incentives, and championing regulations that could dramatically reduce emissions of short-lived climate pollutants.   To see where we are active, click here.
