There is a growing disconnect emerging between what the global food industry says about sustainability and what it can substantiate. A recent scientific analysis has brought that gap into sharp focus, suggesting that much of the sector’s environmental narrative may be built more on messaging than measurable change.
A peer-reviewed study published in PLOS Climate examined sustainability claims made by 33 of the world’s largest meat and dairy companies and found that 98% of those claims could be classified as greenwashing. The findings, now widely reported, point to a systemic issue in how environmental progress is communicated across the industry.
A Sector Talking More Than It Proves
The scale of the analysis is what makes it particularly significant. Researchers reviewed 1,233 environmental claims made between 2021 and 2024, ranging from net-zero commitments to water-saving initiatives and regenerative farming programmes.
Of those claims, only 29% were supported by any form of evidence, and just three were backed by peer-reviewed scientific research. The majority relied on vague language, internal case studies or forward-looking promises without clear delivery frameworks.
A substantial portion, around 38%, consisted of future targets, such as pledges to reach carbon neutrality by 2030 or 2050, often without detailed plans explaining how those goals would be achieved.
The Rise of “Net Zero” Without a Roadmap
One of the study’s most striking conclusions is how widely net-zero commitments have been adopted, and how inconsistently they are supported.
Seventeen of the 33 companies analysed now claim some form of net-zero ambition, a sharp increase from just a handful a few years ago. Yet many of these commitments appear to rely heavily on carbon offsetting rather than direct emissions reduction.
In practical terms, that means companies may be compensating for emissions rather than fundamentally changing production processes, a strategy critics argue delays meaningful decarbonisation.
A High-Impact Industry Under Scrutiny
The scrutiny is heightened by the sector’s environmental footprint. Animal agriculture accounts for a significant share of global greenhouse gas emissions, estimated at around 16.5% worldwide, making it one of the most impactful areas of the food system.
Against that backdrop, sustainability claims carry weight, not just commercially, but politically and socially. The study suggests that when those claims are overstated or unsupported, they risk distorting both consumer perception and policy direction.
Researchers warn that widespread greenwashing can create the illusion of progress, reducing pressure on companies and governments to implement more substantive changes.
Small Initiatives, Big Messaging
Another recurring pattern identified in the analysis is the amplification of small-scale initiatives. Companies frequently highlight pilot programmes or isolated improvements, such as limited renewable energy installations or small regenerative farming trials, as evidence of broader transformation.
While these initiatives may be genuine, their overall impact on global operations is often minimal. The concern is not that progress is absent, but that it is disproportionately represented relative to its scale.
This creates a narrative where incremental change is framed as systemic transition, a distinction that becomes critical in industries with large environmental footprints.
Echoes of Other High-Emission Sectors
The study draws a direct comparison with the fossil fuel industry, where similar patterns of long-term pledges, reliance on offsets and selective disclosure have been widely documented.
In both cases, the risk lies in delay. By presenting a trajectory of improvement without fully committing to structural change, companies may extend existing business models while appearing aligned with climate goals.
A Turning Point for Accountability
The implications extend beyond corporate communication. Increasing scrutiny of sustainability claims is already feeding into legal and regulatory discussions, particularly around how environmental statements are verified and enforced.
There is growing momentum towards stricter reporting standards, clearer definitions of “net zero” and greater accountability for claims made in public disclosures and marketing.
From Narrative to Measurable Change
What this moment ultimately reflects is a broader shift in expectations.
Sustainability is no longer judged by ambition alone. It is being measured by evidence, transparency and delivery.
For the meat and dairy sector, that shift may prove decisive. Because in an industry where environmental impact is both significant and visible, credibility is no longer shaped by what is promised, but by what can be proven.
