Natural Gas Methane Problem Overstated
Research Shows CH4 Leakage A Minor Factor, Within Acceptable Ranges
Public positions on natural gas are strongly influenced by interpretations of the science on fugitive methane emissions. These vary significantly. The self-identified anti-natural gas wing includes professors like Robert Howarth and popular media figures like filmmaker Josh Fox. Other scholars, such as Cornell’s Lawrence Cathles and Council on Foreign Relations’s Michael Levi, have essentially concluded that fugitive methane is mostly a red herring in the coal-versus-gas conversation, and that natural gas can be a suitable “bridge fuel” in power-sector decarbonization. Other institutions like the Environmental Defense Fund concede that natural gas can be an “exit ramp” toward a clean energy future, but insist that fugitive methane must be tightly regulated to ensure that a coal-to-gas transition provides a warming benefit.
