The livestock industry is essential for food security and economic development, according to a draft report by the United Nations’ Food and Agricultural Organization (FAO) that reinforces its defence of practices in the emissions-heavy sector in recent years.
Former and current FAO officials and academics have criticised the document, seen by Climate Home News, for pro-industry bias, cherry-picking data and even “disinformation” about the environmental impacts of animal farming.
The FAO told Climate Home that a final version of the report – part of an assessment consisting of various documents – would be launched in 2025 and that conclusions should not be drawn from the draft text at this stage.
Estimates of livestock’s contribution to greenhouse gas emissions vary, ranging from 12%-20% of the global total – mostly in the form of methane from ruminants like cows and sheep, and carbon dioxide (CO2) released when forests are cut down for pasture.
Methane, which is emitted in cow burps and manure, is a short-lived greenhouse gas that is 84 times more potent than CO2 over 20 years, making it one of the few available levers to prevent climate tipping points being reached in the near term.
In a 2024 survey of more than 200 scientists and sustainable agriculture experts, about 78% said livestock numbers should peak globally by 2025 to start bringing down emissions and help keep global warming to internationally agreed limits.
But the FAO’s draft study offers strong support for growth of the sector, saying livestock’s contributions to food security, nutrition and raw materials for industry make it a “linchpin for human well-being and economic development”.
It is also described as “critical” for food security, “crucial” for global economies, and “indispensable” for development in sub-Saharan Africa.
The report will be submitted to the FAO’s agriculture committee, which has 130 member nations, although the text could change as national representatives thrash out a final version.
Private-sector lobbyists participating as advisors in national delegations are sometimes also able to influence texts under discussion, according to a July report by the Changing Markets Foundation.
One FAO insider, who did not want to be named, told Climate Home the draft FAO report had been “biased towards pushing livestock [with] many national interests behind it”.
The FAO receives around a third of its budget in direct donations from member countries, and the rest in voluntary contributions from the same states and other actors, including businesses and trade associations.
Tech fixes
The 491-page draft report, which was overseen by a scientific advisory committee of 23 experts and peer reviewers, does not assess how diets with more plant protein could improve food security.
One advisory committee member, Professor Frederic Leroy of Vrije Universiteit Brussel, told Climate Home a shift to entirely plant-based diets “would severely compromise the potential for food security worldwide because many of the food nutrients which are already limited in global diets are found in livestock. How much you can move (away from livestock) should be the real investigation.”

The report’s analysis assumes rising meat production as demand surges among a growing world population with higher incomes. In this context, it proposes “expanding the (livestock) herd size”, increasing production through intensified systems, better use of genetic techniques, and improved land management.
“Technological innovations” such as feed additives and supplements to suppress methane are another idea backed by the FAO. Those could include experimental methods such as a vaccine announced last week and funded by a $9-million grant from the Bezos Earth Fund that aims to reduce the number and activity of methane-producing microbes in a cow’s stomach.

The report’s findings, once approved, will be fed into a three-part roadmap for bringing agricultural emissions in line with the Paris Agreement goal of limiting global warming to 1.5 degrees Celsius.
The first instalment, published at the COP28 climate summit, was viewed internally by some FAO experts as a generic placeholder which largely followed an industry-friendly agenda.
One ex-FAO official, who requested anonymity, told Climate Home the latest draft report on livestock ploughs a similar furrow and would set expectations for part two of the 1.5C roadmap.
“The reality is that if they do a (nearly) 500-page report and put 23 experts’ names in front of it, it’s to impress you and say: ‘This is what is going to happen. We’re going to defend the sector’,” the former UN official said.
Making the case for meat
The expert added that the study’s panel was skewed toward intensified livestock systems and had “cherry picked” evidence to justify recommendations pointing in that direction.
Several of the report’s advisory committee members have previously advocated for meat-based diets, and 11 of the study’s contributors work for the International Livestock Research Institute (ILRI), including one of the paper’s committee advisors.
According to the ex-FAO official, ILRI “has been pushing intensified livestock all its life. It’s their identity. It’s what they do.”
The institute co-founded an agribusiness-backed initiative – Pathways to Dairy Net Zero (P2DNZ) – which de-emphasised livestock emissions, framing them as just one of several problems for the industry to tackle.
ILRI did not respond to a request for comment.
IPCC’s input into key UN climate review at risk as countries clash over timeline
Shelby C. McClelland, of New York University’s Center for Environmental and Animal Protection, told Climate Home she was shocked by a repeated claim in the draft FAO report of “a lack of consensus among scientists regarding the contribution of livestock to global greenhouse gas emissions”.
“This downplays and outright ignores overwhelming scientific evidence from the IPCC [Intergovernmental Panel on Climate Change], high-profile papers, and other recent studies,” McClelland said. “A statement like this in a supposedly scientific and evidenced-based review by the UN FAO is alarming given their influence on agenda-setting for global climate action.”
Advisory committee member Leroy countered that it was “dangerous” to talk about a scientific consensus when the metrics used to measure methane compared to other greenhouse gases are constantly evolving.
“This should be part of an open and transparent debate,” he added. “I don’t think we have reached consensus on the way we interpret the effects of livestock agriculture on climate change, the degree of it, how we can measure it and how we can deal with it.”
Scientists at the FAO first alerted the world to the meat industry’s climate footprint when they attributed 18% of global emissions to livestock farming in the seminal 2006 study, Livestock’s Long Shadow. This analysis found that, far from enhancing food security, “livestock actually detract more from total food supply than they provide.”
However, the paper sparked a backlash felt by key experts in the agency’s Rome headquarters, as the FAO hierarchy, industry lobbyists and state donors to its biannual $1-billion budget exerted pressure for a change of direction.
By the time of last December’s COP28, the FAO’s stance had shifted so far that two experts cited in another livestock emissions study called publicly for its retraction. They argued it had distorted their work and underestimated the emissions reduction potential from farming less livestock by a factor of between 6 and 40.

No ‘carte blanche’
Guy Pe’er, a conservation ecologist at the German Centre for Integrative Biodiversity Research and the Helmholtz Centre for Environmental Research, accused the FAO of turning a blind eye to widespread “hyper-intensive grazing practices” and land use change caused by the world’s growing number of mega-farms.
“We’re currently using more land to feed livestock than humans, and that is causing rapid deforestation in Brazil. Ignoring that is outrageous. When an official organisation is producing disinformation like this, I find it extremely irresponsible,” he said.
Leroy told Climate Home that different types of livestock farming should not be conflated. “If you have over-grazing and the pollution of water sources, that’s clearly wrong, but other types of animal agriculture are also net-positive [for the environment],” he said.
If the advisory committee “sees advantages in having livestock agriculture as part of the food system, I think there’s a sound scientific basis to assume that,” he added. “It doesn’t mean that it’s carte blanche or ‘anything goes’ at all.”

FAO draft report backs growth of livestock industry despite emissions
Deaths from heat are notoriously difficult to quantify because of how complex and subjective the process is. It leaves officials with an incomplete picture of who heat kills.
This story is a collaboration between The Texas Tribune and Inside Climate News. Schumacher, Foxhall and Martinez reported for the Tribune, and Pskowski and Baddour reported for ICN.
As corporate America reckons with the climate crisis, business schools are adapting MBAs to focus on climate and sustainability.
In May, the University of Pennsylvania’s Wharton School of Business graduated its first cohort of MBA students with a new Environmental, Social and Governance major. The program came in response to the pressure climate change has placed on businesses and industries to grapple with related financial risks—and capitalize on the transition to renewable energy.

The “monsoon downpour” that triggered deadly landslides in Kerala’s Wayanad district last month was made 10% heavier by human-caused climate change, a new rapid attribution study says.
The landslides followed an “exceptional spell of monsoon rain” on 30 July. They have killed at least 230 people, with more than one hundred people still missing and rescue operations ongoing.
Analysis by the World Weather Attribution (WWA) service shows the rainfall that hit Wayanad on 30 July was the region’s third-heaviest period on record, surpassing even the extreme rainfall that led to flooding in Kerala in 2018.
The team of 24 researchers from India, Malaysia, US, Sweden, Netherlands and UK find that downpours of this intensity have already become 17% heavier in the last 45 years.
In a world where average global temperatures are 2C above pre-industrial levels, they estimate that extreme single-day bursts of rainfall in Kerala could become a further 4% heavier, potentially leading to even more catastrophic landslides.
The study also looks at other “mixed” factors that may have contributed to the high casualties and Wayanad’s “increased susceptibility” to landslides. These include a 62% loss of forest cover in the district and warnings that “failed to reach many people”.
Slippery slope
Wayanad is a mountainous district in northern Kerala in India’s Western Ghats – a chain of mountains older than the Himalaya that runs parallel to the country’s western coast.
With its high elevation and steep slopes – combined with a tendency to receive “prolonged” rainfall and widespread changes to its natural vegetation – Wayanad is highly landslide-prone. It is the most susceptible district to landslides in Kerala, which accounted for 59% of the country’s landslides over 2015-22.
From 22 June onwards, Wayanad saw “nearly continuous” monsoon rainfall, the WWA study says – with some areas recording over 1.8 metres of rain in just a month.
On 30 July, Wayanad witnessed what study author Dr Mariam Zachariah – a research associate at Imperial College’s London’s Grantham Institute for Climate Change – calls “an extreme burst” of more than 140mm of rain in a single day. This is equivalent to nearly a quarter of the rain London receives all year. This rain landed on loose, erodible soils already saturated by two months of monsoon rains.
The first landslide that began at an altitude of 1,550 metres struck the village of Mundakkai at midnight on 30 July, followed by three more landslides within three hours, hitting the villages of Chooralmala and Attamala.
Torrents of mud, water and rock buried several neighbourhoods, swept away victims and collapsed an arterial bridge, delaying rescue operations to the hardest-hit areas.
While state authorities say that the death toll at the time of writing is 231, media reports suggest that the actual number of lives lost to the landslides is greater than 400 – disproportionately impacting migrant workers working in farms, holiday resorts and tea plantations.
In a press briefing, study author Prof Arpita Mondal from the Indian Institute of Technology Bombay said the “scale of the event was so huge that the debris registered a flow of several kilometres”, adding that “body parts have been recovered from downstream rivers as far as tens of kilometres from the location of the landslides”.
The event, she says, was “particularly devastating to two villages – Mundakkai and Chooralmala”, with one official telling News Minute that “I don’t think the Chooralmala ward will exist anymore”.
Monsoon downpour
To put Wayanad’s intense rainfall into its historical context and determine how unlikely it was, the authors analysed a timeseries of one-day maximum rainfall during the June-to-September monsoon season, focusing on northern Kerala.
They find that 140mm of rainfall hit northern Kerala on 30 July 2024, ranking as the third heaviest one-day rainfall event in a record stretching back to 1901.
The intensity of this rainfall surpassed even the “torrential” rainfall that hit large regions of Kerala in 2018, killing more than 40 people and earning the title of Kerala’s “worst floods in nearly a century”.

The authors find that in today’s climate, this intense one-day rainfall is a one-in-50 year event.
Separately, using satellite observations, the authors find that heavy one-day rainfall events over northern Kerala have become about 17% more intense in the last 45 years, in which time the global climate has warmed by around 0.85C.
Attribution
Attribution is a fast-growing field of climate science that aims to identify the “fingerprint” of climate change on extreme-weather events, such as heatwaves and droughts.
In this study, the authors investigated the impact of climate change specifically on the heavy rainfall in northern Kerala on 30 July 2024.
To conduct attribution studies, scientists use climate models to compare the world as it is today to a “counterfactual” world, without the 1.3C of human-caused warming.
The authors find that climate change made the intense rainfall on 30 July around 10% more intense.
This “may not sound like very much, but really, when you are looking at this amount of rainfall, that is a lot of extra rain”, Dr Claire Barnes, a research associate at Imperial College’s London’s Grantham Institute for Climate Change, and author on the study, told the press briefing.
The authors note that Kerala is a mountainous region with “complex rainfall-climate dynamics” and explain that there is a high level of uncertainty in the model results.
However, Zachariah told the press briefing that the study findings are “consistent with Clausius Clapeyron relationship”, which states that the air can generally hold around 7% more moisture for every 1C of temperature rise.
The authors also investigate how rainfall intensity might change as the planet continues to warm. They find that if the planet were to warm to 2C above pre-industrial temperatures, rainfall intensity in northern Kerala is expected to become a further 4% more intense.
The study says that this increase in rainfall intensity is “likely to increase the potential number of landslides that could be triggered in the future”.
(These findings are yet to be published in a peer-reviewed journal. However, the methods used in the analysis have been published in previous attribution studies.)
Land-use change
The Western Ghats and their high-mountain tropical forest ecosystems are internationally recognised as a biodiversity hotspot and influence Indian monsoon weather patterns.
Wayanad is known for its dense forests and rich biodiversity, but it has also seen significant deforestation and land-use change.
While heavy rainfall was “a trigger” for the devastating landslides, human intervention “has played an important role, there’s no doubt about it”, says Madhavan Rajeevan, India’s former Earth sciences secretary who was not involved in the study. He tells Carbon Brief:
“In many interviews with local people, they say that [large-scale] construction work was going on in the worst-hit areas. And that construction [was done] by removing the local [Indigenous people] staying in the forest. But the landslide doesn’t differentiate between rich and poor. If there was no substantial human intervention in that area for the last four or five years, I’m very sure this landslide would not have happened.”
Between 1950 and 2018, Wayanad lost 62% of its forest cover while land under tea plantations grew by 1,800%, according to one study. The district’s high slopes are also host to coffee, pepper, tea and cardamom plantations, as well as being dotted by luxury resorts.
At the same time, a rise in construction and quarrying for building stones in recent years has “raise[d] concerns” among scientists about the impacts on the stability of hill slopes in the area.
On 31 July, the day after disaster struck, India’s climate ministry issued the sixth draft of a notification to classify parts of the Western Ghats as ecologically sensitive areas (ESAs), 14 years after experts had recommended curbs on development in the region.
Environmental lawyer Shibani Ghosh tells Carbon Brief that, to date, 72,000 square kilometres of the Western Ghats identified by these experts “do not even fall within the ambit of any proposed conservation scheme”.
While environmentalists still have “serious apprehensions” about the area that will be excluded from the Western Ghats ESA in the new draft, “had it been declared [even in its unsatisfactory form] by now, environmentally harmful activities would have been regulated, and perhaps the impact of these natural calamities would have been much less”, she adds.
Rajeevan, additionally, points to how the monsoon has changed in Kerala. He says:
“We know that seasonal rainfall is very high in the west coast, it rains continuously for many days and many hours, but the amount used to be very small: in millimetres per hour. But recent studies are suggesting that these shallow clouds are changing into deep convective clouds that drop very heavy rain in a very short spell, and that could be attributed to warming over the Arabian Sea.”
At the same time, forecasting is another issue that the study raises, drawing attention to the fact that warnings failed to reach many and impacts were not specifically spelt out.
In the aftermath of the landslides, whether meteorological authorities warned of heavy rains became the subject of parliamentary debate. But Rajeevan points out that accurate rain warnings alone are not enough:
“Red alerts and yellow alerts for the whole state or a few districts do not translate into a landslide warning. A district collector cannot translate them or take a decision. The Geological Survey of India issued a warning, but it was not alarming and a sophisticated, real-time landslide alert system needs a lot of money.
“The best solution is to identify and rehabilitate people living in landslide prone areas and to not trouble them by removing their forests.”
