The China Mail - Climate Goals Threatened by Industrialised Animal Farming, Reveals Key International Study

Major Insights

• Across global research, livestock farming contributes an estimated 12-20% of all greenhouse gas emissions annually, with the most comprehensive studies yielding the highest figures.

• The most modern accounting methods, which include the impacts of deforestation, bottom trawling and cooling effects from certain atmospheric pollutants, reveal that 52% of present-day global warming is attributable to animal agriculture.

• Animal agriculture occupies over 80% of agricultural land, while providing only 18% of calories and 37% of protein consumed worldwide, making it difficult to meet the needs of a fast-growing future population.

• Among other food-originating environmental impacts, the sector also creates 50% of eutrophication and 32% of soil acidification.

• Rapidly developing regions including emerging economies are projected to experience the sharpest growth in livestock emissions unless production trends shift.

• Biodiversity studies reveal that meat-heavy diets can create three to four times greater biodiversity losses compared to predominantly plant-based diets.

Why a Plant-Based Shift Matters
The analysis makes a compelling environmental case for dietary change. Transitioning toward plant-forward eating patterns would drastically cut greenhouse gas emissions, reduce pressure on forests and freshwater systems, and curb nutrient pollution from feed crops and manure. Such a shift would not only mitigate climate impacts but also help restore ecosystems and safeguard wildlife.

Implications for Policymakers
The authors urge that global climate frameworks-such as climate summits and national plans under the Paris Agreement-must integrate clear targets for reducing animal-product production and consumption. Without tackling this sector, the chances of limiting global warming to well below 2°C (let alone 1.5°C) are significantly compromised.

To be effective and fair, the analysis stresses, solutions must also consider regional realities. In developing economies, dietary transitions should align with food security, cultural preferences, and equitable livelihoods for farmers.

A Turning Point for Food and Climate
"The time is long overdue for greater attention on animal agriculture at key climate and environmental policy-making events such as COP30" stated lead author Jenny Mace. "It would be incredibly difficult to achieve climate and other sustainability targets without a significant downsizing of animal agriculture."

Stated co-author veterinary Professor Andrew Knight, "Industrial livestock farming represents a critical blind spot in global climate policy. However, placing food system reform - particularly the reduction of animal-based products - at the centre of climate action could unlock enormous benefits for both people and the planet."

Co-author Fernanda Vieira of Sinergia Animal commented that, "Industrial-scale farms are a profound driver of biodiversity loss, deforestation, climate change, and the emergence of zoonotic diseases. If we fail to confront these interconnected issues, the prospect of achieving meaningful progress toward our climate, health, and sustainability goals will remain out of reach."
