Gas stoves leak as much methane across the U.S., having the same climate impact as half a million cars, according to a Stanford University study.
Researchers analyzed indoor levels of heat-trapping methane and nitrogen oxides and found significant amounts of each, with leaks occurring even when the appliances were not in use. Both gases can trigger asthma and other respiratory problems as well as contributing to climate change.
The study adds momentum to the movement to ban natural gas use in new buildings to fight climate change. The natural gas industry has mobilized to block such bans.
It’s unclear how much methane is coming from leaky pipes and fittings, incomplete combustion, design features of the stoves, or a combination of all three factors. Researchers based their data on 18 brands of stoves, ranging from 3 to 30 years old.
