Animal lives embodied in food loss and waste

Abstract

While the importance of reducing meat loss and waste is acknowledged due to its substantial environmental impacts, the aspect of animal welfare largely remains unaddressed. The suffering and death that is inflicted on animals to produce food that is never eaten remains invisible. This study aims to bridge the gap between food loss and waste (FLW) accounting literature and animal welfare considerations. It achieves this by estimating the number of animal lives embodied in meat loss and waste of six major meat-producing species along the food supply chain and by modelling three potential reduction scenarios. It shows that approximately 18 billion animal lives were embodied in losses and waste of global meat production and consumption in 2019. The scenarios reveal that wasted and lost animal lives could be reduced by 7.9 billion if best regional efficiencies were mainstreamed, and by 4.2 or 8.8 billion if Sustainable Development Goal 12.3 was implemented, achieving a 50 % loss and waste reduction in the downstream or whole supply chain, respectively. Considering species-specific conscience and sentience, and previous recommendations, the analysis finds leverage points for change at the consumption stage in developed, high-income countries, in Industrialized Asia, judging by absolute, and in North America and Oceania, judging by per-capita numbers, as well as in top countries of FLW and animal life loss. It further identifies trade-offs for animal welfare between reducing FLW of different meat types, especially chicken and beef, and reducing production-based losses while keeping emissions and resource use low and supporting food security.
