NAIROBI / RankWire.AI / – According to the United Nations Environment Programme, the global economy suffers more than $1 trillion each year as a result of food loss and waste. Households alone discard over one billion meals every day. The issue gained renewed attention around the International Day of Awareness of Food Loss and Waste on September 29. UNEP emphasizes that reducing food losses can help conserve land, water, and forests, while also cutting emissions associated with uneaten food.
This problem spans the entire food supply chain and consumer markets. The Food and Agriculture Organization reports that 13.4% of food produced globally is lost after harvest and before reaching retail outlets. An additional 19% of food available to consumers is wasted by households, food service providers, and retailers. UNEP’s 2024 Food Waste Index estimates that 1.05 billion tonnes of consumer-level food waste occurred in 2022, with households responsible for 60% of this total.
Food loss and waste contribute roughly 8% to 10% of worldwide greenhouse gas emissions, UNEP and FAO have noted. Specifically, food waste alone may account for up to 14% of global methane emissions. UNEP programme manager Michael Muratha has stressed the importance of improved handling, storage, transportation, and cold-chain management as practical methods to minimize losses. He also advocates for redistributing safe surplus food as a strategy to keep edible products in use.
Efforts to Minimize Waste Throughout the Food Chain
Technology is increasingly being employed to monitor waste levels in commercial kitchens. A UAE initiative involving Hilton, Winnow, UNEP West Asia, and the Ne’ma national programme tracked breakfast waste across 13 hotels. The project utilized AI tools and plate-waste systems to identify overproduction and discarded food. Winnow’s data indicated a 62% overall reduction in breakfast food waste over four months, rather than a 62% decrease in post-consumer waste alone.
The initiative achieved a 76% reduction in pre-consumer waste and a 55% decrease in post-consumer waste. By analyzing data from the tracking systems, teams optimized food production, buffet layouts, portion sizes, and staff practices. This example demonstrates how technology can support accurate measurement of food waste and foster operational improvements. UNEP has also supported lower-tech solutions, such as community programs that utilize ingredients often discarded during meal preparation.
Global Goals Set on 2030 for Food Waste Reduction
The Food Waste Breakthrough was launched by UNEP and its partners at COP30 in Belém, Brazil, in November 2025. Its objective is to cut global food waste by 50% by 2030, along with reducing methane emissions associated with food waste by up to 7%. During its launch, the initiative received a commitment of $3 million from the Global Environment Facility. The event took place at COP30, clarifying that it was mistakenly associated with COP31 in Brazil in earlier references.
This 2030 target aligns with Sustainable Development Goal 12.3, which aims to halve per-capita food waste at retail and consumer levels. Additionally, it strives to lower losses along food production and supply chains. In September 2026, FAO reported that progress toward this goal had been limited in recent years. Current UN data indicate that food losses and waste remain significant, consuming resources and incurring substantial economic and environmental costs.
