“President Joe Biden signed a bona fide international climate treaty…one that was ratified in the Senate with bipartisan support in a 69-27 vote. Twenty-one Republicans supported ratification in September, including Minority Leader Mitch McConnell.”

“If fully implemented, the measure would avert upward of 0.5 degrees Celsius — almost 1 degree Fahrenheit — of warming by the end of the century. Keeping in mind that the Paris climate agreement aims to hold the rise in global average temperatures below 2 degrees Celsius, the Kigali Amendment would take a big step toward that goal. And it builds on one of the most successful efforts to prevent an environmental disaster in history.”

“Countries around the world convened to try to solve the problem, and in 1987, developed the Montreal Protocol. It was the first treaty to be ratified by every country in the world. Countries began to phase out CFCs entirely. And it worked. The ozone layer is on track to heal entirely. By 2065, the Montreal Protocol is estimated to have prevented 443 million skin cancer cases, 2.3 million skin cancer deaths, and more than 63 million cases of cataracts in the United States alone, according to the State Department.”

“There was an unanticipated problem as well. CFCs were replaced with another class of chemicals called hydrofluorocarbons (HFCs) in many applications. While HFCs aren’t as damaging to the ozone layer, they are powerful greenhouse gases. The Kigali Amendment, drafted in 2016, aims to zero out HFCs as well.”

“why did so many Republicans back Kigali when they’ve criticized just about every other major international environmental agreement? Recall that many Republican lawmakers cheered when then-President Trump began the process of withdrawing the US from the Paris climate accord.
Part of the reason for Kigali’s success may be that conservative stalwarts Margaret Thatcher, a former chemist, and Ronald Reagan, a skin cancer survivor, were framers of the initial Montreal Protocol.
Another is that the amendment comes packaged with solutions. There are already climate-friendly refrigerants on the market, and appliance manufacturers are eager to deploy them. Some lawmakers see this as an opportunity to play to the US’s strengths.
“This amendment will give American manufacturers the ability to continue exporting sustainable coolants and the products that depend on them,” said Sen. John Kennedy (R-LA) in a statement. “Not only does this create tens of thousands of jobs here at home, it protects our markets from becoming a dumping ground for China’s outdated products.””
