Dominion Energy Inc said it plans to cut the amount of methane escaping from its natural gas wells, pipelines and other infrastructure by 50 percent over the next decade as part of its effort to combat global warming.

The company, one of the biggest U.S. power and gas utilities, even held contests among its business units to determine how much methane emissions they could reduce, said Diane Leopold, president and CEO of Dominion’s Gas Infrastructure Group.
