While the methane reduction targets are the same as the draft rule released last August (i.e., 40-45 percent reduction of 2012 levels by 2025), the new rule removes exceptions, resulting in a 30 percent improvement in reductions of methane.

For the first time, electricity generated from burning natural gas will surpass coal, largely due to fracking of shale. While that means that carbon dioxide emissions will continue to drop, it also means that methane emissions will increase.

Unlike Europe where renewable energy is heavily subsidized, very few biogas projects that convert farm waste to energy using anaerobic digesters are being built in the U.S. State incentives are instrumental due to high capital and maintenance costs.

How much methane, a powerful but short-lived greenhouse gas is released during fracking operations for natural gas? Until now, all studies, including those by the EPA, were done by estimates. This study went to over 500 well sites to measure leaks.
