Well, all that produce methane we need.

The White House announced a wide-ranging plan Friday aimed at cutting methane emissions from oil and gas drilling, landfills and other sources.

The plan, part of President Obama’s strategy to reduce greenhouse gas emissions that contribute to global warming, comes amid concerns about increased methane emissions resulting from an ongoing boom in drilling for oil and natural gas.

Methane is a powerful greenhouse gas released by landfills, cattle and leaks from oil and gas production. Methane is 21 times more potent at trapping heat than carbon dioxide, the most abundant global warming gas, although it doesn’t stay in the air as long.

Experts say methane leaks can be controlled by fixes such as better gaskets, maintenance and monitoring. Such fixes are also thought to be cost-effective, since the industry ends up with more product to sell.
