After being transmitted to the U.S. Senate by President Joe Biden, the upper chamber considered the Kigali Amendment to the Montreal Protocol, a United Nations treaty reached in 2016 to significantly phase down the consumption and production of hydrofluorocarbons – highly potent greenhouse gasses found in air-conditioning systems, insulation, and refrigerators. The amendment also requires signatory parties to establish a licensing system for import and export of hydrofluorocarbons. On September 21, the Senate agreed to the resolution of ratification by a vote of 69-27 (Senate roll call vote 343). YES IS THE PRO-ENVIRONMENT VOTE. With this vote, the United States became the 137th country to ratify this treaty. The Environmental Protection Agency had previously issued rules to reduce these climate super-pollutants in line with the treaty’s requirements.
