Our current dietary patterns are pushing Earth beyond safe limits

The dominant dietary patterns in many countries are contributing to pressures that exceed Earth’s ecological limits. Scientists describe these ecological limits through the planetary boundaries framework, which are scientifically defined, interdependent guardrails that ensure the Earth’s health. The framework includes boundaries for climate change, biosphere integrity, freshwater change, and ocean acidification alongside other measures. Today, food production contributes to the crossing of six of these boundaries, making it one of the most significant pressures on Earth’s life-support systems, with animal agriculture playing a central role.12

We are off track for 1.5°C

The global food system is a major driver of climate change, generating approximately 30% of global greenhouse gas emissions. Animal-based foods are responsible for up to 20% of all human-made greenhouse gas emissions. GHG emissions from animal-based foods are twice that of plant-based foods, and if animal-based foods were a country, they would be the second-largest emitter, just below China and above the USA.3456 We cannot solve the problem of climate change unless we also address the problem of food.

More than CO₂ — 
methane is a neglected problem

Methane is a powerful driver of climate change and contributes to ground-level ozone pollution, which is associated with around one million premature respiratory deaths globally each year.78 Farmed animals are responsible for 32% of global human-made methane emissions,9 and reducing methane emissions from animal agriculture is one of the quickest and most effective ways to mitigate or even drastically reduce global warming. Because methane breaks down more quickly than carbon dioxide, cuts made today can deliver near-term climate benefits.10 If the production of farmed animals were a country, it would rank first in methane emissions — emitting as much methane as China, India, and the United States combined.

As methane is a short-lived greenhouse gas reducing the methane emissions from animal agriculture is one of the quickest and most effective ways to mitigate or even drastically reduce global warming. It can provide short-term relief and buy us time for transition processes in other sectors such as energy and transportation.12

Agriculture’s role in biodiversity loss and deforestation

Agriculture is one of the biggest drivers of deforestation and biodiversity loss. Half of the habitable land on Earth is used for agriculture and 80% of that agricultural land is used for farmed animals. However, animal-based foods only provide 18% of global calories.16171819 At the same time, agriculture is listed as a risk to more than half of the species at risk of extinction,20 and globally, 
41% of tropical deforestation is driven by beef production. That is 
2.1 million hectares per year – about the size of Slovenia.2122 What we eat can have a bigger impact on land use than how much we eat. Reducing our reliance on animal agriculture and instead growing crops for direct human consumption can increase efficiency and food security while yielding positive benefits to nature and biodiversity.

ProVeg drives change where food decisions actually get made: in the public institutions that feed millions every day, in the policy frameworks that shape supply chains, and in the retail and food-service companies that determine what’s on the shelf.

Public Food Programme

Reshaping institutional food environments at scale

Every day, schools, universities, and hospitals serve meals to hundreds of millions of people worldwide. The scale is vast, yet historically these systems have not been designed with clear goals around health, climate, or social equity. ProVeg’s Public Food Programme works with these institutions to increase the proportion of plant-based and plant-rich meals served — and to make plant-based defaults the norm.
Food choices are largely shaped by what is offered, how it is presented, and what kitchen teams are equipped to prepare. By improving these conditions — through menu redesign, chef training, procurement policy, and stakeholder engagement — it becomes possible to influence dietary patterns at scale, without relying on individual behavior change alone. Not only does implementing plant-based defaults in public food settings increase the number of people eating climate-friendly meals, it also lowers the climate impact of the food-service provider, with studies reporting between 
20–40% emissions reductions.
Since 2018, the program has supported thousands of schools, universities, and hospitals to replace animal-based meals with plant-based alternatives, and in 2025 alone, we reached over 2 million diners.

Plant-Rich Policy Programme

Policy reform is one of the highest impact interventions we have to positively alter the food system: a single regulatory change can influence billions in public spending and private capital. ProVeg’s Plant-Rich Policy Programme works to embed plant-rich food systems into national strategies, 
EU procurement frameworks, climate plans, and UN processes — 
creating the structural conditions under which markets, institutions, 
and producers can move together.
ProVeg holds Permanent Observer Status with the UNFCCC, special consultative status with ECOSOC, and is accredited for the UN Environment Assembly. We co-drafted the Belém Declaration on Plant-Rich Diets, signed by 122 organizations and policymakers, and have contributed directly to national policies in Portugal (Revised National Energy and Climate Plan), Germany (Federal Protein Strategy), Poland (2050 National Development Concept), and many more across the EU and globally.
In 2025, 41 high-level policymakers publicly endorsed ProVeg’s recommendations and 25 national, EU, and UN policy documents referenced our policy asks.

Corporate Protein Transition Programme

Retail and food service determine what protein billions of people consume day-to-day. Yet most companies have no standardized methodology for measuring the plant-to-animal protein ratio of their sales — and therefore no way to set, track, or report on protein-shift commitments aligned with climate targets. ProVeg’s Corporate Protein Transition Programme closes that gap, working with major retailers and food-service operators in Europe through a Target → Measure → Act strategy: setting ambitious, time-bound protein-balance targets, measuring and disclosing progress, and designing implementation roadmaps for change at scale.
Our Protein Tracker — developed in partnership with the Green Protein Alliance — provides a standardized, retailer-level methodology for measuring plant-to-animal protein sales. In the Netherlands, where ProVeg has supported retailer adoption, participating retailers representing 95% of the Dutch market have committed to ensuring that at least 60% of protein sales will be plant-based by 2030.

Diverse, Collaborative, and Global

While our three global programs guide a majority of our work, we realize that every country, culture, and region is unique. Which is why we have established offices in 14 countries around the world, led by local experts and partnering with diverse stakeholders from across the value chain. We recognize that an intervention that works in one region may not be suited to another. We intentionally leave room for flexibility and adaptability across our programmatic work. This allows us to implement culturally relevant approaches. This looks like providing comprehensive technical support to transition farmers to plant production and agroforestry in Brazil, building coalitions in Portugal to embed agroecological legume production in national climate policy, and in China, accelerating NeoProtein ecosystem development through cross-sector collaboration.

Across our programs and countries we track tangible outputs and outcomes that build the foundation for system-level change. We are developing and refining the tools and frameworks to track key data and analyze effectiveness of programs, understanding the mechanisms that make them successful and their relative cost-effectiveness.

Outputs

Institutional meal transitions

At least 72 million animal-based meals swapped to plant-based alternatives across schools, universities, and hospitals since 2018.

Retail protein shift

The Protein Tracker provides standardized measurement of plant-to-animal protein sales ratios at retailer level — including verified shifts in major markets such as the Netherlands, where 42.6% of protein sales in participating supermarket chains in the Netherlands were plant-based in 2025.

Policy outcomes

including the Belém Declaration on Plant-Rich Diets, Portugal’s Revised National Energy and Climate Plan, Poland’s mandate for one weekly plant-based school meal from 2026, Germany’s Federal Protein Strategy, and many more.

Movement Building

to organizations across 97 countries since 2019, paving the way for locally led, culturally relevant food-system transformation.

Outcomes

GHG emissions avoidance

as a result of key interventions including plant-based meal swaps and retail protein target commitments.

Water and land use

as a result of the adoption of structural shifts from meat-based to plant-based alternatives across institutions and geographies.

The case for food system transformation is clear. We know that shifting towards plant-rich diets is one of the most effective ways to combat the myriad challenges we face, including climate change, land-use pressures, water scarcity, public health, and food insecurity. Join us as we shift global supply and demand to accelerate the transition toward a food system that is good for people, animals, and the planet.
