Phasedown of Hydrofluorocarbons: Establishing the Allowance Allocation and Trading Program under the AIM Act
The AIM Act, which was included in the Consolidated Appropriations Act, 2021, directs EPA to phase down production and consumption of HFCs in the United States by 85 percent over the next 15 years. A global HFC phasedown is expected to avoid up to 0.5° Celsius of global warming by 2100.
This final rule is the first regulation under the AIM Act to address HFCs, which are potent greenhouse gases commonly used in refrigerators, air conditioners, and other applications. This final rule sets the HFC production and consumption baseline levels from which reductions will be made, establishes an initial methodology for allocating and trading HFC allowances for 2022 and 2023, and creates a robust, agile, and innovative compliance and enforcement system.
The EPA Administrator, Michael S. Regan, signed the following notice on 09/23/2021, and EPA is submitting it for publication in the Federal Register (FR). He said the EPA has taken steps to ensure the accuracy of this Internet version of the rule, it is not the official version of the rule for purposes of compliance or effectiveness.
Once the official version of this document is published in the FR, this version will be removed from the Internet and replaced with a link to the official version.
