WASHINGTON In an effort to deliver on President Obama's pledge last summer to tackle emissions that drive climate change, the White House announced a strategy to limit releases of methane, a highly potent greenhouse gas.
The methane strategy, disclosed Friday, is the most recent in a string of climate change initiatives that the White House has unveiled at a rapid pace in recent weeks. It lays the groundwork for regulations that could affect agriculture and the oil, gas and coal industries.
Carbon dioxide from the combustion of fossil fuels is the biggest contributor to climate change, but methane, the chief component of natural gas, is estimated to be more than 20 times more potent at trapping heat in the atmosphere.
Methane emissions make up 9% of the country's greenhouse gas emissions and are on track to increase, officials said. Among the biggest sources of methane going into the atmosphere are leaks from oil and gas facilities; seepage from coal mines; landfills; and livestock, especially cows.
