Healthier livestock could slash emissions and boost global food security

Improving the health of livestock could play a far bigger role in cutting emissions and securing food supplies than previously recognised. A new analysis highlights how better animal welfare delivers measurable benefits—from lower greenhouse gases to reduced waste—without requiring major changes in farming practices or consumer habits. Yet, despite its potential, investment in this area remains surprisingly low.

Healthier dairy cattle in the UK alone could cut carbon emissions by up to 10% for every litre of milk produced. Across Europe, livestock farming already contributes to sustainability by producing nutritious food while using less land and generating fewer emissions than in many other regions. But the impact could be even greater with targeted improvements.

A study by Oxford Analytica found that less than 0.1% of global climate funding currently goes toward animal health measures. The research examined Ethiopia, Kenya, India, and Vietnam, showing how better livestock care directly boosts efficiency and sustainability. Experts argue that good animal health creates a 'triple dividend': it increases resource efficiency, lowers greenhouse gases, and strengthens food security.

In Germany, raising vaccination rates by 20% in the pig sector could prevent the loss of over 65 million servings of pork. It would also cut feed waste by nearly 22 million kilograms. Similarly, in France, higher vaccination coverage against highly pathogenic avian influenza (HPAI) in poultry could reduce losses by a third, saving €5.5 million in production costs.

Despite these clear benefits, barriers remain. Low awareness, unclear financial returns, trade concerns, and misaligned policy incentives slow progress toward more preventive disease management. Many farmers and policymakers still overlook animal health as a key tool for climate action and economic resilience.

Investing in animal health could become a cornerstone of Europe's sustainable food future. The evidence shows it reduces emissions, cuts food losses, and improves efficiency—all without drastic shifts in production or consumer behaviour. Yet realising this potential will require greater funding, policy support, and industry commitment to preventive care.
