The Senate Foreign Relations Committee voted on May 4 to advance the Kigali Amendment to the Montreal Protocol, moving the United States closer to formalizing the phasedown of hydrofluorocarbons (HFCs) already included in the 2020 American Innovation and Manufacturing Act (AIM).
The AIM Act was passed as part of the Consolidated Appropriations Act of 2021 and signed into law by President Trump on Dec. 28, 2020. The Environmental Protection Agency (EPA) has already moved ahead with the reduction in HFC consumption and production, with EPA Administrator Michael Regan issuing a rule based on AIM in September 2021.
HFCs were developed to supplant chlorofluorocarbons (CFC) and other ozone-depleting substances used in refrigerators. The phasedown of ozone-depleting substances started with the Montreal Protocol, which was signed by President Ronald Reagan in 1988 and adopted by every United Nations member state.
While CFC manufacturing has been outlawed since 2010 under that agreement, CFCs have been produced illegally at times after the ban, with investigators tracing some rogue CFC manufacturing to China.
While HFCs don’t damage the ozone layer, they, too, are a danger to the environment; some scientists have estimated their global warming potential to be hundreds of times greater than that of carbon dioxide.
While DuPont, the inventor of CFCs, pushed back against CFC restrictions during the years leading to the Montreal Protocol’s passage, Michaels and Zycher claimed that the company’s current support for the elimination of HFCs is related to its own production of costly HFC alternatives.
DuPont officials didn’t respond by press time to a request by The Epoch Times for comment.
In all, 170 countries have agreed to the 2016 Kigali Amendment to the Montreal Protocol. As with the AIM Act, that amendment obligates parties to slowly curb the production and use of HFCs by 85 percent over 15 years.
However, the Kigali Amendment would restrict trade between signatories and non-signatories by 2033, leading Democratic and Republican lawmakers to push for its passage.
“The AIM Act is already bringing the U.S. into alignment with the Kigali Amendment’s plan to phase down HFCs. It only makes economic sense that the Senate now ratify this agreement to ensure that the U.S. can capitalize on the success of the AIM Act instead of unnecessarily limiting our trade partners and giving our competitors—or even adversaries like China—a leg up at the expense of hardworking Americans,” Carper and Kennedy wrote in that April article.
In November 2021, Carper praised Biden when he first transmitted the amendment to the Senate.
“It’s long past time that we join the rest of the international community in addressing HFCs and taking the kind of bold, transformational climate action that this moment demands,” he said.
Kennedy has argued that passage of the amendment could spur the production of next-generation coolants in his home state of Louisiana, currently a hub for HFC manufacturing.
“Ratifying the Kigali Amendment will expand the global market for American-made technologies and safeguard U.S. investments,” Kennedy said in a statement accompanying his Washington Times op-ed.
A Kennedy aide told The Epoch Times that alternative coolant production in Louisiana includes OxyChem’s manufacturing of the refrigerant constituent 4CPe as well as Honeywell’s production of Solstice ze (1234ze).
“Louisiana is not only home to the chemical manufacturers producing these HFC alternatives, but the state is home to HVAC companies that will begin manufacturing next-generation air conditioning and heating systems,” the spokesperson said.
The committee’s vote moves the Kigali Amendment closer to being ratified by the full Senate.
The only senator on the Foreign Relations Committee who voted “nay” on the amendment was Sen. John Barrasso (R-Wyo.).
