Gas stoves could be responsible for 19,000 premature deaths

According to a new study, gas and propane stoves emit unhealthy amounts of nitrogen dioxide. Regular use of these stoves can increase a household's annual exposure to NO 2 by 4 ppb, or 75% of the long-term exposure limit set by the World Health Organization (WHO) ( Sci. Adv. 2024, DOI: 10.1126/sciadv.adm8680 ). "In other words, just by using gas stoves regularly, you're eating up three-quarters of that guideline, which was established to protect public health," Yannai Kashtan, a PhD candidate at the Stanford Doerr School of Sustainability and lead author of the study, said during a press briefing. Exposure to outdoor sources of NO 2 , such as vehicle traffic, already frequently push people over that guideline, he added. In the US, around 38% of households have gas stoves, which create NO 2 as the burning natural gas heats nitrogen in the surrounding air. Chronic exposure to nitrogen dioxide
