In 1976, beloved chef, cookbook writer, and tv character Julia Child returned to WGBH-TV’s studios in Boston for a brand new cooking present, Julia Child & Company, following her hit sequence The French Chef. Viewers most likely didn’t know that Child’s new and improved kitchen studio, outfitted with gas stoves, was paid for by the American Gas Association.
While this may increasingly seem to be any company sponsorship, we now understand it was part of a calculated marketing campaign by gas industry executives to extend the use of gas stoves throughout the United States. And stoves weren’t the solely goal. The gas industry needed to develop its residential market, and houses that used gas for cooking have been probably additionally to make use of it for warmth and scorching water.
The industry’s efforts went nicely past cautious product placement, in keeping with new analysis from the nonprofit Climate Investigations Center, which analyzes company efforts to undermine local weather science and gradual the ongoing transition away from fossil fuels. As the middle’s examine and a National Public Radio investigation present, when proof emerged in the early Nineteen Seventies about the well being results of indoor nitrogen dioxide publicity from gas range use, the American Gas Association launched a marketing campaign designed to fabricate doubt about the present science.
As a researcher who has studied air air pollution for a few years—together with gas stoves’ contribution to indoor air air pollution and well being results—I’m not naïve about the methods that some industries use to keep away from or delay rules. But I used to be stunned to study that the multipronged technique associated to gas stoves straight mirrored techniques that the tobacco industry used to undermine and warp scientific proof of well being dangers related to smoking beginning in the Fifties.
The gas industry is defending natural gas stoves, that are below fireplace for his or her well being results and their contribution to local weather change.
Manufacturing controversy
The gas industry relied on Hill & Knowlton, the identical public relations firm that masterminded the tobacco industry’s playbook for responding to analysis linking smoking to lung most cancers. Hill & Knowlton’s techniques included sponsoring analysis that may counter findings about gas stoves printed in the scientific literature, emphasizing uncertainty in these findings to assemble synthetic controversy and interesting in aggressive public relations efforts.
For instance, the gas industry obtained and reanalyzed the knowledge from an EPA examine on Long Island that confirmed extra respiratory issues in houses with gas stoves. Their reanalysis concluded that there have been no important variations in respiratory outcomes.
The industry additionally funded its personal well being research in the early Nineteen Seventies, which confirmed massive variations in nitrogen dioxide exposures however didn’t present important variations in respiratory outcomes. These findings have been documented in publications the place industry funding was not disclosed. These conclusions have been amplified in quite a few conferences and conferences and in the end influenced main governmental studies summarizing the state of the literature.
This marketing campaign was outstanding, since the fundamentals of how gas stoves affected indoor air air pollution and respiratory well being have been simple and well-established at the time. Burning gas, together with natural gas, generates nitrogen oxides: The air in Earth’s environment is about 78 p.c nitrogen and 21 p.c oxygen, and these gases react at excessive temperatures.
Nitrogen dioxide is thought to adversely have an effect on respiratory well being. Inhaling it causes respiratory irritation and may worsen ailments similar to bronchial asthma. This is a key cause why the US Environmental Protection Agency established an out of doors air high quality customary for nitrogen dioxide in 1971.
No such requirements exist for indoor air, however as the EPA now acknowledges, nitrogen dioxide publicity indoors can be dangerous.

How dangerous is indoor publicity?
The key query is whether or not nitrogen dioxide publicity associated to gas stoves is massive sufficient to result in well being considerations. While ranges range throughout houses, scientific analysis exhibits that the easy reply is sure—particularly in smaller houses and when air flow is insufficient.
This has been recognized for a very long time. For instance, a 1998 examine that I co-authored confirmed that the presence of gas stoves was the strongest predictor of non-public publicity to nitrogen dioxide. And work courting again to the Nineteen Seventies confirmed that indoor nitrogen dioxide ranges in the presence of gas stoves may very well be far larger than out of doors ranges. Depending on air flow ranges, concentrations may attain ranges recognized to contribute to well being dangers.
Despite this proof, the gas industry’s marketing campaign was largely profitable. Industry-funded research efficiently muddied the waters, as I’ve seen over the course of my analysis profession, and stalled additional federal investigations or rules addressing gas range security.
This concern took on new life at the finish of 2022, when researchers printed a brand new examine estimating that 12.7 p.c of US instances of childhood bronchial asthma—about one case in eight—have been attributable to gas stoves. The industry continues to solid doubt on gas stoves’ contribution to well being results and fund pro-gas range media campaigns.
A priority for local weather and well being
Residential gas use can be controversial right this moment as a result of it slows the ongoing shift towards renewable power, at a time when the impacts of local weather change have gotten alarmingly clear. Some cities have already moved or are contemplating steps to ban gas stoves in new building and shift towards electrifying buildings.
As communities wrestle with these questions, regulators, politicians, and customers want correct details about the dangers of gas stoves and different merchandise in houses. There is room for vigorous debate that considers a variety of proof, however I imagine that everybody has a proper to know the place that proof comes from.
The business pursuits of many industries, together with alcohol, tobacco, and fossil fuels, aren’t all the time appropriate with the public curiosity or human well being. In my view, exposing the techniques that vested pursuits use to control the public could make customers and regulators savvier and assist deter different industries from utilizing their playbook.
