Short-Lived Climate Pollutant Challenge

Reducing emissions of potent short-lived climate pollutants provides outsized global climate benefits in the near-term, along with significant health, agricultural, and ecosystem benefits.  Targeted commitments and strategies to rapidly and significantly reduce these pollutants, which include methane, hydrofluorocarbons (HFCs) and black carbon, will minimize the risks of climate change and maximize local benefits associated with addressing it. Immediate action on these pollutants is necessary to limit the global temperature increase to well below 2°C, and to pursue efforts to limit the increase to 1.5°C.

On June 1, 2018, the U.S. Climate Alliance committed to reducing short-lived climate pollutants as a critical component to meeting the goals of the Paris Agreement. The Alliance invites all national and subnational jurisdictions, businesses and other actors to bring commitments to reduce short-lived climate pollutants to the Global Climate Action Summit in San Francisco, California this September.

In the coming months, the Alliance will work to comprehensively address short-lived climate pollutants, including through new and continued actions to improve emissions inventories; quickly identify and address methane leaks and “super emitters;” promote energy efficiency, including in refrigeration and cooling; phasedown the use of HFCs; improve management of organic and agricultural waste streams; and define other targets and measures to rapidly reduce emissions of these potent pollutants.


Take Action

Join us by committing to reduce super pollutants, and calling on government and business leaders to do the same.  In addition to reaching out to decision-makers directly, help spread the word through social media:

  • Write about the need to reduce SLCP emissions
  • Share what you are doing to reduce emissions
  • Pledge to do more to reduce emissions of SLCPs
