Summary
Poore & Nemecek (2019) present a comprehensive global life-cycle assessment synthesising data on the environmental footprints of diverse food commodities and production systems. The analysis identifies both production-level interventions (farming practice improvements) and consumption-level strategies (dietary shifts, food waste reduction) as pathways to substantially reduce food's environmental burden, suggesting that neither producer nor consumer action alone is sufficient.
UK applicability
The study's global scope and commodity-level findings are relevant to UK food policy and retailer sourcing decisions; however, application requires localisation to UK supply chains and import-dependent food categories. Findings may support UK dietary guidelines and procurement policy but do not address UK-specific soil health or nutrient density outcomes.
Key measures
Greenhouse gas emissions (kg CO₂-eq), land occupation (m²), water use (litres), eutrophying emissions (kg PO₄-eq) across commodity types and production geographies
Outcomes reported
The study quantified environmental impacts (greenhouse gas emissions, land use, water use, eutrophication) across global food production systems and identified opportunities for impact reduction through both producer and consumer interventions.
