In 1976, beloved chef, cookbook creator, and tv character Julia Youngster returned to WGBH-TV’s studios in Boston for a brand new cooking present, Julia Youngster & Firm, following her hit collection The French Chef. Viewers most likely didn’t know that Youngster’s new and improved kitchen studio, outfitted with gasoline stoves, was paid for by the American Gasoline Affiliation.
Whereas this may increasingly seem to be any company sponsorship, we now realize it was part of a calculated marketing campaign by gasoline trade executives to extend the usage of gasoline stoves throughout the US. And stoves weren’t the one goal. The gasoline trade wished to develop its residential market, and houses that used gasoline for cooking have been seemingly additionally to make use of it for warmth and sizzling water.
The trade’s efforts went properly past cautious product placement, in accordance with new analysis from the nonprofit Local weather Investigations Middle, which analyzes company efforts to undermine local weather science and sluggish the continued transition away from fossil fuels. As the middle’s research and a Nationwide Public Radio investigation present, when proof emerged within the early Seventies in regards to the well being results of indoor nitrogen dioxide publicity from gasoline range use, the American Gasoline Affiliation launched a marketing campaign designed to fabricate doubt in regards to the present science.
As a researcher who has studied air air pollution for a few years—together with gasoline stoves’ contribution to indoor air air pollution and well being results—I’m not naïve in regards to the methods that some industries use to keep away from or delay laws. However I used to be stunned to study that the multipronged technique associated to gasoline stoves immediately mirrored techniques that the tobacco trade used to undermine and deform scientific proof of well being dangers related to smoking beginning within the Fifties.
The gasoline trade is defending pure gasoline stoves, that are beneath 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 trade’s playbook for responding to analysis linking smoking to lung most cancers. Hill & Knowlton’s techniques included sponsoring analysis that might counter findings about gasoline stoves revealed within the scientific literature, emphasizing uncertainty in these findings to assemble synthetic controversy and interesting in aggressive public relations efforts.
For instance, the gasoline trade obtained and reanalyzed the info from an EPA research on Lengthy Island that confirmed extra respiratory issues in properties 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 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 the place trade 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, because the 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 % nitrogen and 21 % 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 comparable to bronchial asthma. It is a key cause why the US Environmental Safety Company established an outside air high quality commonplace for nitrogen dioxide in 1971.
No such requirements exist for indoor air, however because the EPA now acknowledges, nitrogen dioxide publicity indoors can also be dangerous.

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 issues. Whereas ranges fluctuate throughout properties, scientific analysis reveals that the straightforward reply is sure—particularly in smaller properties and when air flow is insufficient.
This has been recognized for a very long time. For instance, a 1998 research that I co-authored confirmed that the presence of gasoline stoves was the strongest predictor of private publicity to nitrogen dioxide. And work relationship again to the Seventies confirmed that indoor nitrogen dioxide ranges within the presence of gasoline stoves might be far greater than outside ranges. Relying on air flow ranges, concentrations might attain ranges recognized to contribute to well being dangers.
Regardless of this proof, the gasoline trade’s marketing campaign was largely profitable. Trade-funded research efficiently muddied the waters, as I’ve seen over the course of my analysis profession, and stalled additional federal investigations or laws addressing gasoline range security.
This difficulty took on new life on the finish of 2022, when researchers revealed a brand new research estimating that 12.7 % of US instances of childhood bronchial asthma—about one case in eight—have been attributable to gasoline stoves. The trade continues to solid doubt on gasoline stoves’ contribution to well being results and fund pro-gas range media campaigns.
A priority for local weather and well being
Residential gasoline use can also be controversial at the moment as a result of it slows the continued 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 gasoline stoves in new building and shift towards electrifying buildings.
As communities wrestle with these questions, regulators, politicians, and shoppers want correct details about the dangers of gasoline stoves and different merchandise in properties. There’s room for vigorous debate that considers a variety of proof, however I consider that everybody has a proper to know the place that proof comes from.
The industrial pursuits of many industries, together with alcohol, tobacco, and fossil fuels, aren’t all the time appropriate with the general public curiosity or human well being. For my part, exposing the techniques that vested pursuits use to control the general public could make shoppers and regulators savvier and assist deter different industries from utilizing their playbook.
