Natural gas, long seen as a cleaner alternative to coal and an important tool in the fight to slow global warming, can be just as harmful to the climate, a new study has concluded, unless companies can all but eliminate the leaks that plague its use.
It takes as little as 0.2 percent of gas to leak to make natural gas as big a driver of climate change as coal, the study found.
That’s a tiny margin of error for a gas that is notorious for leaking from drill sites, processing plants and the pipes that transport it into power stations or homes and kitchens.
The bottom line: If gas leaks, even a little, “it’s as bad as coal,” said Deborah Gordon, the lead researcher and an environmental policy expert at Brown University and at the Rocky Mountain Institute, a nonprofit research organization focused on clean energy.
“It can’t be considered a good bridge, or substitute.”The peer-reviewed study, which also involved researchers from Harvard and Duke Universities and NASA and is set to be published next week in the journal Environmental Research Letters, adds to a substantial body of research that has poked holes in the idea that natural gas is a suitable transitional fuel to a future powered entirely by renewables, like solar and wind.
