Methane Emissions Blow Past Current Estimates
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.

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.
