Re: Ratification of the Kigali Amendment to the Montreal Protocol

Dear Chairman Menendez and Ranking Member Risch:

The undersigned organizations urge expeditious Foreign Relations Committee consideration of the Kigali Amendment to the Montreal Protocol, which would enable the full Senate to provide its advice and consent.

We represent the American business community, which strongly supports the Kigali Amendment for the economic and environmental benefits associated with phasing down the production and use of hydrofluorocarbons (HFCs).

We believe the case for ratification is both essential and urgent. Ratification would safeguard the competitiveness of American manufacturers and showcase American climate leadership. The Kigali Amendment would enhance the significant economic opportunities created by The American Innovation and Manufacturing Act, passed by Congress in 2020. For instance, there are estimates that some sectors could directly add 33,000 U.S. manufacturing jobs  over the next decade.  A global HFC phasedown would also avoid up to 0.5° C of warming by 2100.

Accessing global markets for the HFC phasedown is among our highest priorities. We believe even a slight delay in ratification emboldens foreign competitors, undermines U.S. climate action, and delays reduction of HFC emissions. 

We greatly appreciate your attention to this matter and look forward to working with you in the coming weeks in support of Senate approval of the Kigali Amendment.
