Even when they are not running, U.S. natural gas stoves are leaking 2.6 million tons of methane — in carbon dioxide equivalent units — into the air each year, a team of researchers found.
“They’re constantly bleeding a little bit of methane into the atmosphere all the time,” said the study’s co-author Rob Jackson, a Stanford University climate scientist.
“That’s a big deal because we’re trying to really reduce our carbon footprint and we claim that gas is cleaner than coal, which it is,” said study lead author Eric Lebel, a scientist at PSE Healthy Energy, an Oakland nonprofit. But he said much of the benefit disappears when leaks are taken into account.
“Natural gas appliances are generally more energy- and cost-effective than their electric counterparts,” Maisano said.
