Short-Lived Climate Pollutants

CO2 emissions pose the gravest 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 in the near-term.

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 include methane, black carbon (BC), and pollutants that create tropospheric ozone. 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 and mountain regions, where warming is occurring at twice the rate of the rest of the world. By targeting short-lived pollutants we can also improve air quality and human health.

CATF is active in a number of different venues around the globe on supporting scientific research, promoting policy initiatives, encouraging financial incentives, and championing regulations that could dramatically reduce emissions of short lived climate pollutants.
