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.
A potent greenhouse gas, methane is even more effective at trapping heat in the atmosphere than carbon dioxide (see Reference 5).
