Methane is the main ingredient in natural gas, and it packs about 80 times the climate-warming power of carbon dioxide.
Sharon Wilson sets up a thermal imaging camera near a compressor station in Arlington, Texas, Tuesday, Oct. 18, 2022. Wilson, a field advocate for Earthworks, which promotes alternatives to fossil fuels, uses the high-tech camera to detect methane leaks at oil and gas facilities.
Methane is the main ingredient in natural gas. Measured over a 20-year period, scientists say, it packs about 80 times the climate-warming power of carbon dioxide. And according to the International Energy Agency, methane is to blame for roughly 30% of the global warming that has occurred since the Industrial Revolution. Aerial surveys have documentedIt's a problem the Biden administration has sought to attack in its recently enacted Inflation Reduction Act.
“Energy companies have made pledges, but I’ve got to tell you, I haven’t seen anything from a practical standpoint that makes me believe there’s any reality to reductions on the ground,” said Tim Doty, an environmental scientist and former air quality inspector for the Texas Commission on Environmental Quality. “Maybe they’re making progress, but are they making enough progress to slow down climate change? I don’t think so.
Marathon Oil disputed that it violated any regulations. A spokeswoman said the company recognizes the impact of greenhouse gas emissions on the global climate and prioritizes concern for the environment. “All this stuff is going to be prone to leak — that’s just the way it is,” said Coyne Gibson, who spent about two decades as an engineer inspecting oil and gas equipment. “That’s mechanics. And there’s there’s not really any way to avoid it.”
Much of the time, though, there is no such surveillance. Leaks or even planned methane releases can occur during these periods, as when companies open a stretch of pipeline to release methane before doing repairs. The staffing it would take to continuously survey the nation's 3 million miles of natural gas pipelines would likely be prohibitively expensive.
