Climate impact of gas stoves in U.S. equal to half a million cars

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.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
