December 12, 2012 – UNITED STATES – Natural gas has been hailed by some as a crucial bridge fuel to a cleaner energy future. But how much cleaner is burning natural gas than burning oil or coal? Concern over water contamination from fracking for natural gas aside, some argue that the much-advertised climate advantage of natural gas may be all but offset by the steady release of methane during its long journey from the well to the 65 million American households that depend on natural gas. Molecule per molecule, methane has more than 20 times the global warming potential of carbon dioxide.
