Holding Retail Corporations Accountable for Food Waste: A Due Diligence Framework Informed by Business and Human Rights Principles

Retail corporations orchestrate much of what happens in today's food supply chains. From setting sky-high cosmetic standards for fresh produce to bundling off close-to-expiry products at discounted prices, retail's contribution to food waste often extends beyond its in-store numbers. By occupying a powerful position in a globalised food system, these corporations enable chronic overproduction and consequently, the removal of surplus food from supply chains. This, in turn, contributes to the unfair distribution and overexploitation of food resources, further exacerbating the globally pervasive problem of food insecurity. To realise the right to food and the United Nations' Sustainable Development Goal of halving global per capita food waste by 2030, we argue that retail corporations must be held accountable for their direct and indirect contribution to food waste. We posit that to make a tangible difference, they must move away from the current voluntary corporate social responsibility approach to food waste reduction and instead invest in robust due diligence mechanisms and transparent reporting systems in line with the UN Guiding Principles on Business and Human Rights and the upcoming EU Corporate Sustainability Due Diligence Directive. Based on Pillar II of the Guiding Principles, we propose a five-step approach to accountability for food waste that may lead to serious actions towards the relaxation of cosmetic standards, abolition of unfair trading practices, and improvement in demand forecasting, thereby reducing the volume of food that ends up as waste.
