The US Senate voted Wednesday to join more than 130 nations in pledging to phase out the use of super-polluting greenhouse gases found in refrigerators and air conditioners, a step that is expected to avoid as many greenhouse gas emissions as the entire planet emits every two years. 

By a vote of 69 to 27, the Senate ratified the 2016 Kigali amendment to the Montreal Protocol. Two-thirds of the senators present were required to vote yes for ratification.
