Summary
Poore and Nemecek's 2019 synthesis integrates life-cycle assessment data across global food production systems to quantify environmental impacts per unit of food. The analysis evaluates mitigation pathways at both producer level (farming practice and efficiency improvements) and consumer level (dietary composition changes), providing comparative environmental footprinting across major food categories. This multidisciplinary assessment addresses the dual levers for reducing food's environmental burden.
UK applicability
The findings on high-impact food categories and mitigation strategies are directly applicable to UK food production and consumption patterns, informing policy on sustainable food systems and dietary guidance. UK producers and retailers may use the comparative footprinting data to benchmark environmental performance and set reduction targets.
Key measures
Life-cycle assessment metrics including greenhouse gas emissions, land occupation, freshwater use, eutrophication potential per kilogramme of food produced
Outcomes reported
Quantified environmental impacts (greenhouse gas emissions, land use, water use, eutrophication) per unit of food produced across major food categories. Identified mitigation opportunities at producer level (farming practice improvements, efficiency gains) and consumer level (dietary shifts).
