Reducing food’s environmental impacts through producers and consumers

Summary

This meta-analysis consolidated environmental data from approximately 38,000 farms producing 40 agricultural commodities globally to quantify variability in production impacts. The research demonstrates substantial heterogeneity in environmental costs among producers of the same goods, creating targeted mitigation opportunities, whilst also highlighting that lowest-impact animal products typically exceed the environmental costs of vegetable alternatives. The findings underscore both the complexity of supply-chain mitigation and the potential role of dietary change in reducing food's environmental footprint.

UK applicability

The study's global dataset and identification of high-impact producers may inform UK agricultural and environmental policy, though UK-specific farm and supply-chain data would be needed to translate findings to domestic production systems and consumer guidance.

Key measures

Five environmental indicators across ~38,000 farms and 1,600 processors, packaging types, and retailers; comparative environmental costs by product type and production system

Outcomes reported

The study quantified environmental impacts across approximately 38,000 farms producing 40 different agricultural commodities, measuring variability in environmental costs among producers of identical products. It identified substantial heterogeneity in production impacts and assessed the comparative environmental footprints of animal versus plant-based food products.
