International Day of Zero Waste 2026
International Day of Zero Waste: Promoting Sustainable Consumption
Observed on March 30, this day is organized by UNEP and UN-Habitat. It highlights the urgent need for better waste management, as the world generates over 2.1 billion tonnes of municipal solid waste annually. A significant focus for 2026 is reducing the 1 billion tonnes of food wasted globally, which contributes to 10% of greenhouse gas emissions.
