On Tuesday, 63 nations, including the United States, joined a pledge to cut down cooling-related emissions at the COP28 United Nations climate summit in Dubai, United Arab Emirates. The Global Cooling Pledge requires countries to reduce such emissions by at least 68 percent by 2050 compared to 2022 levels. The focus of cooling-related emissions would be on appliances like air conditioners and refrigerators. The pledge also proposes setting up minimum energy performance standards for appliances by 2030.

"We want to lay out a pathway to reduce cooling-related emissions across all sectors but increase access to sustainable cooling," said Mr. Kerry, who joined representatives from other countries in the pledge, Reuters reported.

Rep. Jeff Van Drew (R-N.J.) criticized the pledge in a Dec. 6 X post: "John Kerry lost his run for president & has been trying to assert his revenge on everyday Americans ever since. If he gets his way, our cars, our appliances, and food will be gone. All from a man who flies around on his wife's private jet."
