Obama Aims for Huge Cut in Methane Emissions From Natural Gas Wells (NBC News)

Methane is emitted naturally from geothermal systems, but those emissions are minimal at 0.5% Dry Gas % by Volume

The Obama administration laid out a blueprint Wednesday for the first regulations to cut down on methane emissions from new natural gas wells, aiming to curb the discharge of a potent greenhouse gas by roughly half.

Relying once again on the Clean Air Act, the rules join a host of others that President Barack Obama has ordered in an effort to slow global warming despite opposition to new laws in Congress that has only hardened since the midterm elections. Although just a sliver of U.S. greenhouse gas emissions, methane is far more powerful than carbon dioxide at trapping heat in the atmosphere.

The White House set a new target for the U.S. to cut methane emissions by 40 percent to 45 percent by 2025, compared to 2012 levels. To meet that goal, the Environmental Protection Agency will issue a proposal affecting oil and gas production, while the Interior Department will also update its standards for drilling to reduce leakage from wells on public lands.
