On 14 December 2022, the United Nations General Assembly adopted a resolution at its seventy-seventh session to proclaim 30 March as International Day of Zero Waste, to be observed annually. First International Day of Zero Waste was celebrated on 30 March, 2023.

• The International Day of Zero Waste aims to promote sustainable consumption and production patterns, support the societal shift towards circularity and raise awareness about how zero-waste initiatives contribute to the advancement of the 2030 Agenda for Sustainable Development.
• Humanity generates an estimated 2.24 billion tons of municipal solid waste annually, of which only 55 per cent is managed in controlled facilities.
• Every year, around 931 million tons of food is lost or wasted and up to 14 million tons of plastic waste enters aquatic ecosystems.
