U.S. Enacts HFC Phase-Down Law as Part of COVID Relief Bill

EPA is charged with establishing allowance program to cut HFC production/consumption by 85% by 2036, in line with yet-to-be-ratified Kigali Amendment.

In a long-awaited move supported by a coalition of business and environmental stakeholders, the U.S. government has enacted bipartisan legislation authorizing a 15-year phase down of HFCs in alignment with the Kigali Amendment to the Montreal Protocol.

Originally introduced in January 2020 by the U.S. House of Representatives following a similar bill in the Senate, the American Innovation and Manufacturing Act of 2020 (AIM) requires the Environmental Protection Agency (EPA) to implement a phase down of the production and consumption of HFCs in order to reach approximately 15% of their 2011-2013 average annual levels by 2036.

AIM is part of a sweeping bipartisan legislative package, the Consolidated Appropriation Act, 2021, which includes a $1.4 trillion government spending bill and $900 billion COVID-19 relief package bill. President Trump, who will be replaced by President-Elect Joe Biden on January 20, signed the Act on December 27.

AIM will:

  • Phase down the production and consumption of HFCs through an allowance program
  • Authorize the EPA to establish standards for the management of HFCs used as refrigerants through recovery, reclamation and improved servicing, repair, and disposal practices. This could reverse an EPA rule enacted in 2020 that rescinded a rule extending refrigerant leak repair requirements to HFCs and HFOs for equipment containing more than 50lbs (23kg) of refrigerant, including most supermarket and industrial applications.
  • Create a three-year grant program for small businesses, allocating $5 million annually toward increasing recovery and reclamation of refrigerants at end of life.
  • Authorize the EPA to establish sector-based use restrictions, facilitating the transition to next-generation technologies.

The AIM law includes a list of pure HFCs targeted for phase down that is largely the same as that used in the Kigali Amendment. For HFCs like R404A, which consists of a blend of pure HFCs, “the allowances will be for the HFC components,” said Christina Starr, Senior Policy Analyst for the Environmental Investigation Agency (EIA). “So if you were producing or importing R404A, you’d need allowances for corresponding amounts of R125, R143A, and R134a.”

For HFC-HFO blends, only the HFC portion would be subject to allowance limits, she added.

Return to federal action

By implementing these measures, the EPA will resume its regulation of HFCs, which had been sidelined by the U.S. Court of Appeals ruling in 2017, and then by the EPA’s decision to expand upon that ruling.

In the absence of federal action, a number of states, led by California, have adopted the SNAP rules on HFCs, among other measures. California’s Air Resources Board last month approved new regulations that expand the state’s refrigerant restrictions considerably, including a 150-GWP cap on refrigerants used in new commercial and industrial equipment, beginning in 2022.

AIM would provide a more standard approach to HFC regulation across all states, though it would not prevent California from following thorugh on its stricter provisions as they apply to refrigeration and air conditioning, noted Starr.  Federal allocation rules would take over for niche applications deemed an “essential use” for which there are no alternatives, she added.

In general, the AIM law “paves the way for the Biden Administration to increase the ambition and effectiveness of our domestic federal policy framework to reduce HFCs,” said Starr in a statement. “It doesn’t go as far as we’d ultimately like in requiring complete elimination of these gases, but the broader authority it gives EPA to better manage and restrict HFCs throughout their lifecycle provides more tools to increase emission reductions to meet net-zero emission targets.”

While AIM aligns the U.S. with the 85% phase down of HFCs required under the Kigali Amendment for developed countries by 2036, the Trump administration has not sent the Amendment to the  U.S. Senate for ratification. However, Biden has said that he intends to “embrace” the Kigali Amendment in his first 100 days. He also intends to support “refrigeration and air conditioning using refrigerants with no global warming potential.” (Ammonia (R717) is the only refrigerant with zero GWP; he may have meant zero or “near-zero” GWP refrigerants like CO2 (R744) and propane (R290)).

Avipsa Mahapatra, Climate Campaign Lead for EIA, described the AIM law as “the most significant climate legislation to pass in the U.S. congress in over a decade.” Moreover, she said, “It sends a signal that one of the largest contributors to climate change, the United States, is back at the global climate action table, after four years of appalling inaction.”
