Obama aims to cut methane emissions 45 percent

President Obama’s latest effort to mitigate the effects of climate change will be to crack down on methane leakage from oil and gas wells, The New York Times reported.

The EPA will announce new regulations this week aimed at reducing methane emissions by 45 percent by 2025, compared with 2012 levels. Final rules will be set by 2016, the newspaper reported, citing anonymous sources.

Obama, stymied by Republican opposition that stands to become more solidified now that the party controls the Senate as well as the House, has increasingly turned to executive action, skirting Congress, to deal with climate change. The administration says the Clean Air Act gives it the green light to issue such mandates.

Methane, the primary component of natural gas, sometimes escapes from oil and gas wells, in addition to pipelines. Although the gas accounts for only 9 percent of overall greenhouse-gas emissions, it’s 20 times more potent than carbon dioxide, another GHG that accounts for the majority of emissions.

The Natural Resources Defense Council applauded the proposed regulations, but the oil and gas industry said they’re unnecessary, since they’re already motivated to capture methane instead of allowing it to escape into the atmosphere. If it’s captured, it can be burned in power plants to generate electricity, making it a cleaner alternative to coal. Methane can also be used to fuel cars and trucks, as compressed (CNG) or liquefied (LNG) natural gas. It can also be converted into two types of inexpensive liquid alcohol fuels, ethanol or methanol.

Howard Feldman, director of regulatory affairs for the American Petroleum Institute, said:

“We don’t need regulation to capture it, because we are incentivized to do it. We want to bring it to market.”

That market would grow if the infrastructure for transportation fuels were expanded, creating more of an incentive to capture methane. The price of natural gas stood at $12.68 per million metric British Thermal Units (MmBTU) in June 2008, only to crash to $1.95 by April 2012. Last month the average was $3.43 at the Henry Hub terminal in Louisiana. Profit margins are still so low that oil drillers flare off much of it.
