FORUM: “Food Waste.” International Day of Zero Waste 2026. This year’s observance focuses on food waste, a critical yet preventable driver of environmental harm. The world is wasting food at an alarming scale, undermining food security and slowing progress toward a zero-waste, circular future. In 2022 alone, approximately 1 billion tonnes of food, nearly one-fifth of all food available to consumers, was wasted. Food loss and waste represent a major climate and environmental threat. They account for up to 10% of global greenhouse gas (GHG) emissions, nearly five times the emissions from the aviation sector, and up to 14 per cent of global methane emissions. Tackling food waste is among the most cost-effective and readily achievable climate solutions, aligned with zero-waste approaches that prioritize prevention, resource efficiency and systemic change. Governments, businesses, and individuals must embrace zero waste to overcome the waste pollution crisis. UNEP and UN-Habitat call on stakeholders – including governments, civil society, businesses, academia, communities, women and youth – to participate in national, subnational, regional and local zero-waste initiatives. Follow the conversations with the hashtags: #sdg12, #zerowasteDay, #30March.
