Summary
This comprehensive meta-analysis synthesised life cycle assessment data for major food products and production systems worldwide, quantifying environmental impacts across greenhouse gases, land use, water consumption, and nutrient pollution. The work as suggested by its title identified intervention points for reducing food's environmental footprint through both producer-side practices and consumer-side dietary choices. The analysis spans multiple production systems and geographic regions to enable cross-commodity and cross-regional comparison.
UK applicability
The global scope and commodity-level analysis provide relevant benchmarking for UK food producers and policy-makers seeking to contextualise domestic production impacts and set evidence-based environmental targets. However, UK-specific production conditions, climate, and supply chain structures may differ from global averages included in the synthesis.
Key measures
Greenhouse gas emissions (kg CO₂-eq), land use (m² per kg product), freshwater use (L), eutrophication potential (kg PO₄-eq) across food commodities and production geographies
Outcomes reported
The study assessed environmental impacts (greenhouse gas emissions, land use, water use, eutrophication) across major food commodities and production systems. It evaluated mitigation opportunities available to both producers and consumers.
