Congressional negotiators announced they had reached agreement on a $900 billion COVID-19 economic relief package Sunday night. The legislation, which is expected to be passed by both chambers and signed by the president Monday, includes measures to direct spending to boost renewable energy and limit the use of chemicals used in refrigerators that are extremely potent heat trapping greenhouse gasses. The COVID relief bill effectively requires American companies to comply with the 2016 Kigali Amendment to the Montreal Protocol, and reduce production and consumption of hydrofluorocarbons (HFCs) to about 15% of 2012 levels by 2036. This measure is popular among American manufacturers, many of which already produce less-heat-trapping HFC alternatives. (New York Times $, Bloomberg $)
