Summary

This study reveals previously unquantified environmental externalities of global food loss and waste, specifically examining impacts on air quality and biodiversity across food production regions. Rather than focusing solely on technological mitigation, the authors argue for incentivising FLW reduction as a strategy to simultaneously improve ecosystem health and air quality. The work identifies geographic priority areas where food waste reduction could deliver substantial co-environmental benefits.

UK applicability

Findings may inform UK food waste policy by highlighting air quality and biodiversity co-benefits of domestic waste reduction, though the global scope suggests UK-specific analyses would be needed to assess localised impacts and appropriate intervention points within the supply chain.

Key measures

Air quality impacts, biodiversity loss, food loss and waste distribution by geography and food type, ecosystem health metrics

Outcomes reported

The study quantified the air quality and biodiversity impacts associated with global food loss and waste (FLW) across production systems. The research identified geographic hotspots where FLW reduction could yield significant co-benefits for ecosystem health and atmospheric pollution.
