In 1976, beloved chef, cookbook writer, and tv character Julia Youngster returned to WGBH-TV’s studios in Boston for a new cooking show, Julia Child & Company, following her hit sequence The French Chef. Viewers in all probability didn’t know that Youngster’s new and improved kitchen studio, outfitted with gasoline stoves, was paid for by the American Gas Association.
Whereas this may occasionally seem to be any company sponsorship, we now comprehend it was part of a calculated marketing campaign by gasoline trade executives to increase the use of gas stoves across the United States. And stoves weren’t the one goal. The gasoline trade needed to develop its residential market, and houses that used gasoline for cooking have been seemingly additionally to make use of it for heat and hot water.
The trade’s efforts went properly past cautious product placement, in response to new research from the nonprofit Climate Investigations Center, which analyzes company efforts to undermine local weather science and sluggish the continuing transition away from fossil fuels. As the middle’s research and a National Public Radio investigation present, when proof emerged within the early Nineteen Seventies concerning the well being results of indoor nitrogen dioxide publicity from gasoline range use, the American Fuel Affiliation launched a marketing campaign designed to fabricate doubt concerning the current science.
As a researcher who has studied air pollution for many years—together with gasoline stoves’ contribution to indoor air air pollution and well being results—I’m not naïve concerning the methods that some industries use to avoid or delay regulations. However I used to be shocked to study that the multipronged technique associated to gasoline stoves straight mirrored techniques that the tobacco trade used to undermine and distort scientific evidence of well being dangers related to smoking beginning within the Fifties.
The gasoline trade is defending pure gasoline stoves, that are underneath hearth for his or her well being results and their contribution to local weather change.
Manufacturing controversy
The gasoline trade 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 tactics included sponsoring analysis that may counter findings about gasoline stoves printed within the scientific literature, emphasizing uncertainty in these findings to assemble synthetic controversy and fascinating in aggressive public relations efforts.
For instance, the gasoline trade obtained and reanalyzed the info from an EPA study on Long Island that confirmed extra respiratory issues in houses with gasoline stoves. Their reanalysis concluded that there have been no important variations in respiratory outcomes.
The trade additionally funded its personal well being research within the early Nineteen Seventies, which confirmed giant variations in nitrogen dioxide exposures however didn’t present important variations in respiratory outcomes. These findings have been documented in publications where industry funding was not disclosed. These conclusions have been amplified in quite a few conferences and conferences and in the end influenced main governmental reviews summarizing the state of the literature.
This marketing campaign was outstanding, for the reason that fundamentals of how gasoline stoves affected indoor air air pollution and respiratory well being have been easy and well-established on the time. Burning gas, together with pure gasoline, generates nitrogen oxides: The air in Earth’s environment is about 78 percent nitrogen and 21 percent oxygen, and these gases react at excessive temperatures.
Nitrogen dioxide is understood to adversely affect respiratory health. Inhaling it causes respiratory irritation and may worsen ailments corresponding to bronchial asthma. This can be a key cause why the US Environmental Safety Company established an out of doors air high quality standard for nitrogen dioxide in 1971.
No such requirements exist for indoor air, however because the EPA now acknowledges, nitrogen dioxide exposure indoors is also harmful.

How dangerous is indoor publicity?
The important thing query is whether or not nitrogen dioxide publicity associated to gasoline stoves is giant sufficient to result in well being considerations. Whereas ranges range throughout houses, scientific analysis reveals that the easy reply is sure—particularly in smaller houses and when air flow is insufficient.
This has been identified for a very long time. For instance, a 1998 study that I co-authored confirmed that the presence of gasoline 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 within the presence of gasoline stoves could be far higher than outdoor levels. Relying on air flow ranges, concentrations may attain levels known to contribute to health risks.
Regardless of this proof, the gasoline trade’s marketing campaign was largely profitable. Business-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 gasoline range security.
This subject took on new life on the finish of 2022, when researchers printed a brand new research estimating that 12.7 % of US circumstances of childhood bronchial asthma—about one case in eight—were attributable to gas stoves. The trade continues to cast doubt on gas stoves’ contribution to health effects and fund pro-gas stove media campaigns.
A priority for local weather and well being
Residential gasoline use can be controversial right this moment as a result of it slows the continuing shift towards renewable vitality, at a time when the impacts of local weather change are becoming alarmingly clear. Some cities have already moved or are contemplating steps to ban gas stoves in new construction and shift toward electrifying buildings.
As communities wrestle with these questions, regulators, politicians, and customers want correct details about the dangers of gasoline stoves and different merchandise in houses. There may be room for vigorous debate that considers a spread of proof, however I consider 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 always compatible with the public interest or human health. For my part, exposing the techniques that vested pursuits use to control the general public could make customers and regulators savvier and help deter other industries from using their playbook.
