Reducing food's environmental impacts through producers and consumers (vol 363, eaaw9908, 2019)

Joseph Poore, Thomas Nemecek

2019

All evidence

Summary

This comprehensive meta-analysis synthesised life-cycle assessment data across food commodities to quantify the environmental impacts of different production systems and identify high-impact foods and regions. The work evaluated both producer-side interventions (farming practice and efficiency improvements) and consumer-side strategies (dietary shifts and waste reduction) as levers for reducing food's environmental footprint. As one of the largest such syntheses available in 2019, the study provided evidence-based guidance for policy and dietary recommendations on sustainable food choices.

UK applicability

The study's global findings on high-impact foods and production regions are directly relevant to UK food policy and procurement decisions. UK-specific applicability would depend on the proportion of UK food derived from domestic versus imported sources and how UK production systems compare to the global averages reported.

Key measures

Greenhouse gas emissions, land use, water use, eutrophication potential across food commodities and production systems; comparative impacts of producer-side and consumer-side interventions

Outcomes reported

The study quantified environmental impacts (greenhouse gas emissions, land use, water use, eutrophication) across food commodities and production systems globally. It identified high-impact foods and regions, and evaluated both producer-side interventions (farming practice improvements) and consumer-side strategies (dietary shifts, waste reduction) as mechanisms for reducing food's environmental footprint.
