Chris Franke, senior manager of global sustainability at Walmart, and Janelle Meyers, chief sustainability officer at Kellanova, stress the urgency of reducing food waste, as currently one-third of all food produced is wasted each year, contributing to 8% of total global emissions. With 10% of the world’s population lacking adequate food, the need for action is evident. The UN Environment Programme estimates that 13% of food is wasted during farming, production, and transportation, necessitating collective action from food companies, retailers, farmers, and manufacturers. Food manufacturers and retailers are key players in this effort, as they can lead global initiatives to reduce food loss. Walmart focuses on increasing the sell-through of food products by enhancing forecasting tools, inventory management, and offering discounts on near-expiration food. Kellanova works to maximise raw material conversion and donates food to combat food insecurity. The authors suggest a three-pronged plan involving waste assessment, waste reduction initiatives, and technology adoption, urging industry collaboration and inspiring consumer behaviour change. The Consumer Goods Forum’s Food Waste Coalition of Action, which includes major retailers and manufacturers, is at the forefront of global food loss reduction efforts.
