Significant Measure Approved to Reduce Potent Greenhouse Gas Emissions

Significant Measure Approved to Reduce Potent Greenhouse Gas Emissions

NOAA science expertise and data has supported the U.S. government decision to reduce potent greenhouse gas emissions. On September 21st, the United States Senate successfully approved the Kigali Amendment of the Montreal Protocol with strong bipartisan support. The Kigali Amendment, negotiated under the Obama administration in 2016, is an international agreement to phase-out and replace hydrofluorocarbons, a class of chemicals that act as potent greenhouse gasses.

New research estimates the future emissions of potent greenhouse gases

New research estimates the future emissions of potent greenhouse gases

New research published in Atmospheric Chemistry and Physics projects future emissions of hydrofluorocarbons (HFCs), a class of potent greenhouse gasses, based on recent trends and compliance with current policies. The ability to observe trends of these compounds in the atmosphere is made possible by the long-term record of observations produced by the Halocarbons and other Atmospheric Trace Species (HATS) Division within NOAA’s Global Monitoring Laboratory.
