In 1976, beloved chef, cookbook writer, and tv character Julia Baby returned to WGBH-TV’s studios in Boston for a brand new cooking present, Julia Baby & Firm, following her hit collection The French Chef. Viewers in all probability didn’t know that Baby’s new and improved kitchen studio, outfitted with fuel stoves, was paid for by the American Fuel Affiliation.
Whereas this will likely look like any company sponsorship, we now realize it was part of a calculated marketing campaign by fuel trade executives to enhance using fuel stoves throughout america. And stoves weren’t the one goal. The fuel trade wished to develop its residential market, and houses that used fuel for cooking have been probably additionally to make use of it for warmth and sizzling water.
The trade’s efforts went properly past cautious product placement, in response to new analysis from the nonprofit Local weather Investigations Heart, 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 Nineteen Seventies concerning the well being results of indoor nitrogen dioxide publicity from fuel 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 air pollution for a few years—together with fuel stoves’ contribution to indoor air air pollution and well being results—I’m not naïve concerning the methods that some industries use to keep away from or delay laws. However I used to be shocked to be taught that the multipronged technique associated to fuel stoves immediately mirrored ways that the tobacco trade used to undermine and warp scientific proof of well being dangers related to smoking beginning within the Nineteen Fifties.
The fuel trade is defending pure fuel stoves, that are beneath hearth for his or her well being results and their contribution to local weather change.
Manufacturing controversy
The fuel 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 ways included sponsoring analysis that might counter findings about fuel stoves printed within the scientific literature, emphasizing uncertainty in these findings to assemble synthetic controversy and interesting in aggressive public relations efforts.
For instance, the fuel trade obtained and reanalyzed the info from an EPA research on Lengthy Island that confirmed extra respiratory issues in houses with fuel stoves. Their reanalysis concluded that there have been no vital variations in respiratory outcomes.
The trade additionally funded its personal well being research within the early Nineteen Seventies, which confirmed massive variations in nitrogen dioxide exposures however didn’t present vital 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 stories summarizing the state of the literature.
This marketing campaign was outstanding, for the reason that fundamentals of how fuel stoves affected indoor air air pollution and respiratory well being have been simple and well-established on the time. Burning gasoline, together with pure fuel, generates nitrogen oxides: The air in Earth’s ambiance 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 might worsen illnesses similar to bronchial asthma. This can be a key cause why the US Environmental Safety Company established an out of doors air high quality normal 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 fuel stoves is massive sufficient to result in well being issues. Whereas ranges fluctuate throughout houses, scientific analysis exhibits that the straightforward 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 research that I co-authored confirmed that the presence of fuel stoves was the strongest predictor of private publicity to nitrogen dioxide. And work relationship again to the Nineteen Seventies confirmed that indoor nitrogen dioxide ranges within the presence of fuel stoves could possibly be far larger than outside ranges. Relying on air flow ranges, concentrations might attain ranges recognized to contribute to well being dangers.
Regardless of this proof, the fuel 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 fuel range security.
This difficulty took on new life on the finish of 2022, when researchers printed a brand new research estimating that 12.7 p.c of US instances of childhood bronchial asthma—about one case in eight—have been attributable to fuel stoves. The trade continues to solid doubt on fuel stoves’ contribution to well being results and fund pro-gas range media campaigns.
A priority for local weather and well being
Residential fuel use can also be controversial right this moment as a result of it slows the continued shift towards renewable vitality, at a time when the impacts of local weather change are changing into alarmingly clear. Some cities have already moved or are contemplating steps to ban fuel 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 fuel stoves and different merchandise in houses. There may be room for vigorous debate that considers a spread of proof, however I imagine 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 at all times suitable with the general public curiosity or human well being. For my part, exposing the ways that vested pursuits use to govern the general public could make shoppers and regulators savvier and assist deter different industries from utilizing their playbook.
