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.
