Cornell scientists say methane leaks from ‘fracking’ could be worse than emissions from coal and oil

April 12th, 2011

A Cornell review of natural gas extraction methods reveals that ‘fracking’ gas from the Marcellus Shale region of New York and Pennsylvania could release dangerous amounts of methane gas, causing more damage to the atmosphere per pound than even carbon dioxide.

Natural gas, which burns cleaner (producing less carbon dioxide) than gasoline, diesel fuel and coal has been touted as a greener “bridge fuel” that could power cars and replace coal in power plants. Tailpipe emissions from natural gas-powered vehicles emit few greenhouse gases.

But Cornell ecologist Robert Howarth warns that the natural gas extraction or drilling process releases dangerous amounts of methane, a greenhouse gas far more potent than carbon dioxide. The methane leakage is the worse when the gas is accessed by the hydraulic fracturing or ‘fracking’ methods that have become popular with the industry. Fracking is a way of teasing out deeply embedded gas deposits using high pressure water injections in wells that run both vertically and horizontally through shale deposits.
