NAIROBI / RankWire.AI / – According to United Nations data, governments, companies, and households can reduce food waste through improved storage, smarter purchasing strategies, and more precise tracking methods. The UN Environment Programme estimates that over one billion meals are wasted daily in households worldwide. The economic toll of food loss and waste surpasses $1 trillion annually, emphasizing the magnitude of a challenge that impacts food security, natural resources, and greenhouse gas emissions.
Food loss occurs at multiple stages both before and after reaching consumers. The Food and Agriculture Organization states that 13.4% of global food production is lost from harvest to retail. Additionally, 19% of the food available to consumers ends up wasted in homes, restaurants, and stores. UNEP’s estimates indicate that consumer-level food waste was about 1.05 billion tonnes in 2022, with households responsible for roughly 60% of this total and the remaining portion attributed to food services and retail outlets.
The environmental consequences extend beyond mere waste. Food loss and waste are responsible for approximately 8% to 10% of worldwide greenhouse gas emissions. Organic materials from discarded food emit methane if not properly recovered or treated. Practical solutions such as improving storage, transportation, and cold-chain logistics have been highlighted by UNEP programme manager Michael Muratha. Additionally, redistribution programs can divert safe surplus food from landfills to those in need, instead of disposal sites.
Advancements in Technology Enhance Food Waste Monitoring
In the United Arab Emirates, hotels have experimented with artificial intelligence as a means to curb waste. A collaborative project involving Hilton, Winnow, UNEP West Asia, and the Ne’ma initiative encompassed 13 hotels. Teams tracked breakfast waste, utilizing the data to modify kitchen production, buffet layouts, and portion sizes. Winnow reported a 62% overall reduction in breakfast food waste over the four-month trial, covering both kitchen and plate waste across the participating hotels.
The initiative achieved a 76% decrease in pre-consumer waste and a 55% decline in post-consumer waste. Digital tracking systems enabled kitchen staff to identify foods prepared or served in excess, guiding changes in purchasing, preparation, and service based on waste data. UNEP has also advocated for simpler methods that don’t rely on advanced technology. Community programs can promote better meal planning, food storage, and the utilization of ingredients that often go unused.
Global Initiative Aims to Halve Food Waste by 2030
International efforts are aligned with a 2030 objective to reduce food waste significantly. UNEP and its partners introduced the Food Waste Breakthrough during COP30 in Belém, Brazil, in November 2025. This initiative aims to cut global food waste by 50% by the year 2030. It also seeks to decrease methane emissions from discarded food by up to 7%. The Global Environment Facility committed $3 million to support this project at the climate conference.
This goal supports Sustainable Development Goal 12.3, which advocates for halving per-capita food waste at retail and consumer levels. It also emphasizes reducing food losses throughout production and supply chains. While FAO continues to monitor losses occurring before food reaches stores, UNEP measures waste closer to the point of consumption. The data collectively reveal that large quantities of food still exit the system at every stage. Strategies such as storage, measurement, redistribution, and improved planning remain vital tools for addressing these losses.
