But the conference, held from Nov. 6 to Nov. 20, 2022, in Sharm el-Sheik, Egypt, fell short of a hoped-for agreement to speed reductions of greenhouse gas emissions.

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.

As the production of natural gas from shale fields has expanded, so have methane emissions. U.S. methane emissions grew 27 percent from 1990 to 2009, according to the Energy Information Administration. Methane contributes about 10 percent of all U.S. greenhouse gas emissions and is 25 times more potent a greenhouse gas than carbon dioxide.
