reports for Climate Central. "Natural gas emits about half as much climate change-driving carbon dioxide as coal." But there's a caveat.
"Though natural gas burns cleaner than coal, producing natural gas and piping it to power plants leaks methane into the atmosphere," Magill writes. "Methane is a greenhouse gas more than 35 times as potent as carbon dioxide in driving climate change over the span of a century, and global atmospheric concentrations of it have been increasing steadily since 2007. That increase has been tied partly to U.S. natural gas production." The report did not account for methane leaks, which are difficult to measure.
