While Friday’s return is heavily symbolic, world leaders say they expect America to prove its seriousness after four years of being pretty much absent. They are especially anticipating an announcement from the U.S. in coming months on its goal for cutting emissions of heat-trapping gases by 2030.
The U.S. return to the Paris agreement became official Friday, almost a month after President Joe Biden told the United Nations that America wants back in. “A cry for survival comes from the planet itself,” Biden said in his inaugural address. “A cry that can’t be any more desperate or any more clear now.”
Implementation of the Paris Agreement requires economic and social transformation, based on the best available science. The Paris Agreement works on a 5- year cycle of increasingly ambitious climate action carried out by countries. By 2020, countries submit their plans for climate action known as nationally determined contributions (NDCs).
