"The American oil and gas industry is leaking more methane than the government thinks — much more, a new study says. Since methane is a powerful greenhouse gas, that is bad news for climate change.
The new study, published Thursday in the journal Science, puts the rate of methane emissions from domestic oil and gas operations at 2.3 percent of total production per year, which is 60 percent higher than the current estimate from the Environmental Protection Agency. That might seem like a small fraction of the total, but it represents an estimated 13 million metric tons lost each year, or enough natural gas to fuel 10 million homes.
Thanks to a boom in hydraulic fracturing in states like Texas and Pennsylvania, natural gas has quickly replaced coal as the leading fuel used by America’s power plants. It has also helped, to some extent, in the fight against climate change: When burned for electricity, natural gas produces about half the carbon dioxide that coal does. The shift from coal to gas has helped lower CO₂ emissions from America’s power plants by 27 percent since 2005."
