"WASHINGTON — The Obama administration on Friday announced a strategy to start slashing emissions of methane, a powerful greenhouse gas released by landfills, cattle, and leaks from oil and natural gas production.
The methane strategy is the latest step in a series of White House actions aimed at addressing climate change without legislation from Congress. Individually, most of the steps will not be enough to drastically reduce the United States’ contribution to global warming. But the Obama administration hopes that collectively they will build political support for more substantive domestic actions while signaling to other countries that the United States is serious about tackling global warming.
In a 2009 United Nations climate change accord, President Obama pledged that by 2020 the United States would lower its greenhouse gas emissions 17 percent below 2005 levels. “This methane strategy is one component, one set of actions to get there,” Dan Utech, the president’s special assistant for energy and climate change, said on Friday in a phone call with reporters."
