for The Hill

A major question facing American energy and climate policymakers today is what role abundant U.S. natural gas should play in the global clean energy transition. Some environmental activists oppose all gas use. But a new report from the Progressive Policy Institute (PPI) finds that expanding U.S. liquefied natural gas exports can lower global greenhouse gas emissions significantly, especially if fugitive emissions of methane are deeply reduced.

The climate benefits of America’s shale gas revolution have been evident domestically for years. More than three-fifths of total U.S. carbon dioxide emissions reductions over the period 2005 to 2020 were due to coal-fired power plants being replaced by natural gas plants.

In the last year, since Russia’s invasion of Ukraine, the U.S. has also become the world’s largest liquefied natural gas (LNG) exporter, more than doubling deliveries to Europe. This has helped the EU’s economy withstand the cutoff of most Russian gas, with clear geopolitical and economic benefits. Less appreciated are the emissions reductions achieved, since American LNG has limited the growth in the EU’s coal and also reduced use of higher methane-leaking Russian gas.
