A long-awaited study led by the University of Texas at Austin shows that methane emissions from natural gas drilling sites are about 10 percent lower than recent estimates by the U.S. Environmental Protection Agency.
The research adds fresh fuel to the debate over whether natural gas is less carbon-intensive than coal. Although natural gas power plants emit smaller quantities of greenhouse gases than coal-fired plants, the production and distribution of natural gas release large amounts of methane, creating uncertainty about the fuel’s overall climate impact. Methane is 20 to 100 times more potent than carbon dioxide as a greenhouse gas.
