On a quiet morning in Shaoxing, China, a city of over 5 million people, families will gather not just for breakfast, but for change. On 20 September 2026, Shaoxing becomes the global heart of World Cleanup Day, where the fight against food waste takes center stage. Every year, more than one billion meals — enough to feed every person in Europe twice — are thrown away while millions go hungry. This year’s theme, 'From Clean Plates to Clean Cities', turns our everyday choices into a movement for cleaner, fairer cities.
Food waste isn’t just about leftovers. It’s a hidden crisis that chokes landfills, heats up the planet, and wastes precious resources like water and energy. When we toss uneaten food, we also throw away all that went into growing it — the soil, the rain, the labor. According to the UNEP Food Waste Index Report 2024, 1.05 billion metric tons of food were wasted globally in 2022. That’s nearly one-fifth of all food available to consumers. Meanwhile, 673 million people faced hunger in 2024, and over 2.3 billion struggled with food insecurity.
The environmental cost is staggering. Food waste is responsible for up to 10% of global greenhouse gas emissions — more than the entire aviation industry. It also drains the global economy of about $1 trillion every year. But this problem has solutions. Countries already making progress show that with clear policies, better measurement, and public action, food waste can be cut in half by 2030 — a target set under UN Sustainable Development Goal 12.3.
The global event in Shaoxing will bring together governments, schools, businesses, and communities to share ideas, launch clean-up drives, and build smarter food systems. From composting programs to school campaigns teaching kids to save food, real change starts locally. UN-Habitat is inviting cities and groups worldwide to register their events, turning a single day into a wave of action. By linking clean plates to clean streets, the campaign shows how small habits — like finishing a meal or planning groceries — can add up to big impact.
World Cleanup Day was officially recognized by the United Nations in December 2023, when all member states agreed to observe 20 September each year. Now, with Shaoxing lighting the way in 2026, the world has a chance to rethink waste, rebuild systems, and make sure no meal is ever taken for granted again.
