The following is a statement by Darci Vetter, Global Head of Policy and Government Relations for The Nature Conservancy, after the U.S. Senate voted 69-27 to join 137 other countries in ratifying the 2016 Kigali Amendment to the Montreal Protocol:

“The ratification of the Kigali Amendment demonstrates the power of bipartisan action in the battle against climate change and affirms the U.S. commitment to reducing greenhouse gas emissions. Hydrofluorocarbons (HFCs) pack a big punch—with a thousand times the heat-trapping ability of carbon dioxide.

“This vote builds on the strong bipartisan support for the American Innovation and Manufacturing Act of 2020, which directed the U.S. Environmental Protection Agency to reduce the production and use of HFCs by 85%. In addition, the ratification marks the first time in 30 years that the United States has ratified a climate treaty and—combined with the climate and clean energy provisions in this year’s Inflation Reduction Act—demonstrates the nation’s resolve to be a leader in addressing the global climate crisis.

“We commend the bipartisan leadership in the Senate, especially Sens. Bob Menendez and James Risch—the chair and the ranking member of the Senate Committee on Foreign Relations, respectively—for working diligently to bring this treaty to a successful vote.”
