International Day of Zero Waste 2026

The International Day of Zero Waste is a United Nations observance aimed at promoting sustainable consumption and production patterns while raising awareness of the global waste crisis.

Established by the UN General Assembly in 2022 and observed annually on 30 March, the day encourages governments, businesses, and communities to advance zero-waste solutions and support the transition to more circular and resource-efficient systems.

Facilitated by the United Nations Environment Programme (UNEP) and UN-Habitat, the observance highlights how waste reduction and improved resource management contribute to the Sustainable Development Goals, including responsible consumption and climate action.

The day is marked globally through awareness campaigns, policy discussions, and educational initiatives that showcase zero-waste practices and encourage collaboration across sectors.
