NOAA’s observations help inform U.S. greenhouse gas emissions reporting for hydrofluorocarbons

For the first time, the U.S. Environmental Protection Agency (EPA) has included a comparison of NOAA’s atmospheric emission estimates of four hydrofluorocarbons (HFCs) to its own inventory-based estimates in the just-released U.S. Inventory of Greenhouse Gas Emissions and Sinks, based on results first reported in the 2017 Geophysical Research Letters study by a team of NOAA, CIRES, and EPA scientists.
