Zero Waste Day 2026 Campaign Brief

The International Day of Zero Waste, established by United Nations General Assembly resolution 77/161, is jointly facilitated by the United Nations Environment Programme (UNEP) and the United Nations Human Settlements Programme (UN-Habitat). Observed annually on 30 March, Zero Waste Day brings together governments, organizations, businesses, communities and individuals to take action by eliminating waste, embracing circular solutions and creating a cleaner, healthier planet. In 2026, the theme will spotlight food waste, highlighting the connections between food systems, climate action and sustainable development, and inspiring global efforts to prevent and reduce food loss and waste.
