International Day of Zero Waste observed on 30 March to promote sustainable living and reduce waste

The International Day of Zero Waste is observed globally on March 30.
This year’s focus is on reducing food waste and promoting sustainable consumption practices.
According to global estimates, nearly 1 billion tonnes of food are wasted every year, accounting for about one-fifth of food available to consumers.
It was established by the United Nations General Assembly in 2022, with the first official observance in 2023.
The day highlights the importance of sustainable consumption and production patterns, waste prevention, and circular economy practices.
The UN Environment Programme (UNEP) and UN-Habitat lead the global observance, encouraging governments, businesses, and communities to rethink how resources are used and to minimize waste generation.
