Summary

This paper provides updated global estimates of food loss and waste across the supply chain, quantifying the associated nutritional and environmental consequences. The authors synthesise available data to demonstrate the scale of nutritional opportunities foregone and environmental pressures intensified by losses at production, post-harvest, processing and consumer stages. The work underscores the need for targeted interventions to reduce losses and realise food security and sustainability benefits.

UK applicability

The findings are relevant to UK food security policy and environmental targets, particularly regarding circular economy objectives and waste reduction commitments. UK-specific loss and waste data may differ from global averages, but the methodological framework and impact categories should inform national food system resilience planning.

Key measures

Food loss and waste volumes; nutritional content lost (calories, macronutrients, micronutrients); environmental indicators (greenhouse gas emissions, water use, land use)

Outcomes reported

The study quantifies global food loss and waste across the supply chain and estimates the nutritional and environmental pressures resulting from these losses. It likely presents updated estimates of the scale, composition and impacts of food loss and waste at regional and global levels.
