Methane emissions from the global fossil fuel industry are up to 60 percent greater than existing estimates, according to a
new comprehensive analysis
of global methane emissions.
Map showing global methane concentrations in January 2016 at a pressure of 400 hectopascals, or roughly 6km above the surface. Concentrations are higher in the northern hemisphere because both natural- and human-caused sources of methane are more abundant there.
The unaccounted-for emissions are 300 times more than California’s
Aliso Canyon leak
According to current estimates, the fossil fuel industry
contributes about 22 percent
of global methane emissions and about 30 percent
of total U.S. methane emissions
. Methane has a
higher warming potential
than carbon dioxide in the short term.
