This rule will continue to implement the hydrofluorocarbon (HFC) phasedown under the American Innovation and Manufacturing (AIM) Act. A prior rulemaking established an initial framework for the allowance allocation and trading program to phase down HFC production and consumption over time, and also established the production and consumption baselines, codified the list of controlled substances that will be covered by those baselines, determined an approach to allocating annual allowances and allowing for trading of those allowances, established recordkeeping and reporting requirements, introduced a robust, agile, and innovative compliance and enforcement system, and addressed other related elements. To continue phasing down the production and consumption of listed HFCs on the schedule listed in the AIM Act, this rulemaking will provide the framework for how the Agency will issue allowances in 2024 and later years.
