‘Not on course’: US emissions set for 3% decline in 2023
U.S. emissions are on track to fall by as much as 3 percent in 2023, according to a pair of recent analyses — reversing two years of flat or increasing output of planet-warming pollution.
The projected drop is particularly notable as it comes during a year when the U.S. economy is set to expand by almost 2.5 percent — a sign that emissions are decoupling from economic growth. It also represents one of the largest annual emission declines of the last decade.

More than 30 years after the last major update of the Clean Air Act, the U.S. Supreme Court has upended the ability of Congress to give the Environmental Protection Agency and other federal agencies broad scope to combat air pollution, including the emission of greenhouse gases. Meanwhile, further Biden administration efforts to limit emissions face opposition in the courts.
