"WASHINGTON — In President Obama’s latest move using executive authority to tackle climate change, administration officials will announce plans this week to impose new regulations on the oil and gas industry’s emissions of methane, a powerful greenhouse gas, according to a person familiar with Mr. Obama’s plans. The administration’s goal is to cut methane emissions from oil and gas production by up to 45 percent by 2025 from the levels recorded in 2012.

The Environmental Protection Agency will issue the proposed regulations this summer, and final regulations by 2016, according to the person, who spoke on the condition of anonymity because the administration had asked the person not to speak about the plan. The White House declined to comment on the effort.

Environmental advocates have long urged the Obama administration to target methane emissions, and the rules would be the first to do so. Most of the planet-warming greenhouse gas pollution in the United States comes from carbon dioxide, which is produced by burning coal, oil and natural gas. Methane, which leaks from oil and gas wells, accounts for just 9 percent of the nation’s greenhouse gas pollution — but it is over 20 times more potent than carbon dioxide, so even small amounts of it can have a big impact on global warming."
