Critics of the natural gas extraction technique known as fracking have long criticized it for leaking too much methane â a potent greenhouse gas â into the atmosphere during the extraction process.he Environmental Protection Agency recently estimated that natural gas operations emitted about 145 million metric tons of methane in 2011, making it the biggest source of these emissions in the country.
Carbon dioxide is the main one, because the atmosphere holds 200 times as much of it. But a given amount of methane traps at least 25 times as much heatâunless you burn it first. Then it enters the atmosphere as COâ. Thatâs the other side of this Jekyll-and-Hyde story: A lot of methane is being burned these days. In the past decade the technology called hydraulic fracturing, âfrackingâ for short, has enabled drillers in the United States to extract natural gas from deeply buried shales they couldnât tap before.
