In the late 1980s a class of chemicals, hydrofluorocarbons (HFCs), were developed to replace chlorofluorocarbons (CFCs), which were used mainly in refrigeration and air conditioning. CFCs were determined to be ozone-depleting substances (i.e., damaging to the earth’s ozone layer) and, therefore, are being phased out under the Montreal Protocol. 

Although HFCs have supplanted CFCs for use in refrigeration and air conditioning, these substances have now been identified as also contributing to climate change, with global warming potentials of hundreds or even thousands of times higher than carbon dioxide. Other uses of HFCs include fire suppression, aerosols, and foam production. 

In the October 5, 2021, issue of the Federal Register, the U.S. EPA finalized rules under 40 CFR Part 84 to phasedown the production and consumption of HFCs beginning in 2022, based on a fixed percentage of baseline production and consumption.  As of January 1, 2022, production and consumption will be limited to 90% of baseline with incremental reductions resulting in only 15% of production and consumption allowed in 2036 and thereafter. The production and consumption baselines have been set at 375 million metric tons and 299 million metric tons, respectively. EPA will provide public notice of the list of companies authorized with production and consumption allowances of HFCs. These companies will be subject to recordkeeping and reporting requirements.
