President Donald Trump signed an executive order Monday directing the United States to again withdraw from the landmark Paris climate agreement, according to Associated Press.
Trump’s action, hours after he was sworn in to a second term, echoed his directive in 2017, when he announced that the U.S. would abandon the global Paris accord. The pact is aimed at limiting long-term global warming to 2.7 degrees Fahrenheit (1.5 degrees Celsius) above pre-industrial levels or, failing that, keeping temperatures at least well below 3.6 degrees Fahrenheit (2 degrees Celsius) above pre-industrial levels.
Trump also signed a letter to the United Nations indicating his intention to withdraw from the 2015 agreement, which allows nations to provide targets to cut their own emissions of greenhouse gases from the burning of coal, oil and natural gas. Those targets are supposed to become more stringent over time, with countries facing a February 2025 deadline for new individual plans.
The outgoing Biden administration last month offered a plan to cut U.S. greenhouse gas emissions by more than 60% by 2035.
Trump’s order says the Paris accord is among a number of international agreements that don’t reflect U.S. values and “steer American taxpayer dollars to countries that do not require, or merit, financial assistance in the interests of the American people.”
China several years ago passed the United States as the world’s largest annual carbon dioxide emitting nation. The U.S. — the second biggest annual carbon polluting country — put 4.9 billion metric tons of carbon dioxide in the air in 2023, down 11% from a decade earlier, according to the scientists who track emissions for the Global Carbon Project. But carbon dioxide lasts in the atmosphere for centuries, so the United States has put more of the heat-trapping gas that is now in the air than any other nation. The U.S. is responsible for nearly 22% of the carbon dioxide put in the atmosphere since 1950, according to Global Carbon Project.
