From the Document: "Many fluorinated and chlorinated substances, including hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), are potent greenhouse gases (GHGs). Multiple scientific assessments conclude that anthropogenic GHGs (e.g., carbon dioxide [CO2], HFCs, and CFCs) have been a major driver of observed climate change since 1950. Recent legislative proposals--S. 2754, the American Innovation and Manufacturing Act of 2019, and H.R. 5544, the American Innovation and Manufacturing Leadership Act of 2020--would establish a schedule to reduce domestic HFC production and consumption. S. 2754 and H.R. 5544 would require implementation by the U.S. Environmental Protection Agency (EPA) and an 85% reduction by 2036 compared to a 2011-2013 baseline."
