In a study that tested emissions around stoves in homes, concerns have been raised about indoor air quality and health because of levels of nitrogen oxides measured. It found the stoves also contribute more than previously thought to climate change.
“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.
Jackson estimated that when all natural gas use and extraction is taken into account, about 100 million tons of gas leaks into the atmosphere. And the couple million tons from gas stoves “is meaningful. That’s a substantial part and it’s a part that we haven’t included accurately in the past.”

What Happens if Russia Cuts Off Europe's Natural Gas?While Russia masses troops and military equipment near its border with Ukraine, parallel tensions have been building in world energy markets. It is not hard to see why. Natural gas flowing through a web of pipelines from Russia heats homes and power factories across much of Europe. Russia is also one of the continent’s key sources of oil. Now Western officials are considering what happens if Moscow issues a doomsday response to the tensions — a cutoff of those gas and oil supplies, in the depths
