Congressional Democrats this week urged the Environmental Projection Agency to strengthen its proposal to regulate planet-warming methane gas emissions from the country's oil and gas sector.
The letter, led by Sen. Martin Heinrich, N.M. and Rep. Diana DeGette, Colo., and signed by a total of 76 lawmakers, said the agency's proposal needs to tighten restrictions on routine gas flaring, or the process of burning excess natural gas at an oil well.
Methane, a key component of natural gas, is 84 times more potent than carbon dioxide when it comes to warming the atmosphere, but it doesn't last as long in the atmosphere before it breaks down.
A recent study published in the journal Science suggested that oil field flaring emits nearly five times more methane than previously thought.
The process often doesn't completely burn the methane, and in some cases, flares are extinguished and not reignited, causing the methane to release into the atmosphere.
