Archive study finds U.S. cattle lobby answered early methane science with public relations
University of Miami researchers found the National Cattlemen's Association knew by 1989 that cattle methane contributed to global warming. Its records, analysed in PLOS Climate, show a response built on public relations to keep consumers buying beef.

What happened
- In February 1989 an association representative attended an EPA workshop whose report listed feeding changes, feed additives and manure management as ways to cut livestock methane.
- Later in 1989 the association drew up an environmental strategic plan to counter criticism of the industry, commission expert papers and promote a positive environmental image.
- It hired academic experts as report writers and spokespeople, monitored environmental groups and the press, and circulated talking points minimising cattle's role in warming.
- For Earth Day 1990 it put $100,000 into full-page newspaper advertisements, and the records estimate their reach at 20 million people.
Compiled by The ScientistSomething wrong?How this is made
Why it matters
- constraint A livestock methane share quoted against all global sources, natural ones included, understates the sector, so any such percentage has to come with its denominator before it can be compared.
- precedent Climate-delay research built on fossil fuel archives now has a livestock case, putting other food trade groups' records from the same era in scope for the same archival method.
- constraint With an incomplete archive and no data on what individual ranchers did, the finding applies to the association's messaging and cannot be stretched to cover the industry's conduct on farms.
One widely circulated industry-sponsored estimate put U.S. beef cattle at 0.5% of global methane emissions [7]. The trouble is the denominator. According to Jacquet and Loy, the estimate set U.S. cattle against worldwide methane from human activities and natural sources combined, a comparison that would shrink almost any single national sector. They also found the figure difficult to reproduce [7].
The stewardship advertising was cheap per head. The Earth Day newspaper campaign works out to about half a cent per estimated reader [17]. That reach is an estimate recorded in the archive, not an audience measurement [8].
The study is archival. Jacquet, a professor of environmental science and policy at the University of Miami's Rosenstiel School, and Loy, a postdoctoral researcher there, collected 154 internal organizational documents and read them against media coverage and government reports from 1986 to 1996 [3][14][1]. That design can establish what the association knew and what it chose to say. "The records show that the trade association understood the issue and knew that options to reduce methane emissions existed," Jacquet said [11]. Some reports the association commissioned did mention feeding changes that would cut methane. The authors found no evidence in the association's own materials that it researched or promoted any such practice [9].
The authors caution that the archive does not contain all of the association's internal records [10]. Their findings also do not establish whether individual ranchers or companies pursued emissions cuts on their own [10].
The science was young when all this happened. In the mid-1980s, studies increasingly identified livestock as a methane source, from digestion and from manure management, and the debate over responsibility for warming widened beyond fossil fuels [15]. Across the decade that followed, the association questioned global warming itself and challenged campaigns urging people to eat less beef [16]. The study documents tactics similar to those found in research on fossil fuel interests, with one distinct focus: opposing voluntary changes in what consumers eat [13].
"The trade association's main concern was the possibility that consumers would change what they ate," Jacquet said. "That helps explain why its response centered on public messaging." [12]
I think the fossil fuel comparison holds for the tactics: hired experts, a minimising statistic, attacks on the messengers. The target was different. This group was defending a grocery decision. The study as reported does not measure whether the campaigns changed how much beef Americans ate.
What to watch
- A recalculation of U.S. beef cattle's methane share against human sources alone, the comparison the 0.5% estimate did not make.
- Release of the association's internal records missing from the archive, which could show whether its position changed after 1996.
- Research on whether individual ranchers or companies cut methane between 1986 and 1996, the question the authors say their findings do not settle.

Researchers at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science analyzed internal documents, media coverage and government reports to trace how the National Cattlemen's Association responded to emerging scientific evidence about methane emissions from 1986 to 1996.

A leading U.S. beef industry trade association, the National Cattlemen's Association, knew by 1989 that cattle contributed to global warming but focused its response on protecting consumer demand through public relations.

The study was published Oct. 7, 2026, in PLOS Climate and authored by Jennifer Jacquet, a professor in the Department of Environmental Science and Policy at the Rosenstiel School, and Loredana Loy, a postdoctoral researcher at the Rosenstiel School.

In February 1989, an association representative attended a U.S. Environmental Protection Agency workshop that examined livestock methane emissions and ways to reduce them; the resulting report identified potential changes to feeding practices, feed additives and manure management.

Later in 1989, the association developed an environmental strategic plan that included countering criticism of the cattle industry, commissioning papers from scientific and technical experts and promoting a positive environmental image.
- [6]
Documented strategies included monitoring environmental groups and news coverage, hiring academic experts to produce reports and serve as spokespeople, distributing talking points that minimized cattle's contribution to global warming, and challenging the credibility of advocates promoting dietary change.

A widely circulated industry-sponsored estimate put U.S. beef cattle's contribution at 0.5% of global methane emissions; the researchers found the figure difficult to reproduce and that it measured U.S. cattle against worldwide emissions from both human activities and natural sources.

For Earth Day in 1990, the association spent $100,000 on full-page newspaper advertisements that reached an estimated 20 million people, according to records reviewed in the study.

Although some commissioned reports mentioned ways to reduce methane through changes in feeding, the researchers found no evidence in the association's own materials that it researched or promoted practices to address emissions.

Methane is produced by cattle during digestion and released through manure management; in the mid-1980s studies increasingly identified livestock as a methane source, broadening discussions of responsibility for global warming beyond fossil fuels.

The association questioned global warming, downplayed beef production's contribution and challenged campaigns encouraging consumers to eat less beef.

The Earth Day 1990 advertising spend came to about half a cent per estimated person reached.
