Zero Waste Starts on Your Plate

For this year’s International Day of Zero Waste, the focus is on food – what we eat, what we waste, and how we can move towards a more circular future.

The world wastes food on a staggering scale. Every year we throw away about 1 billion tonnes of edible food, nearly one-fifth of all food available to consumers. This impacts both people and the environment.

Around 60 per cent of food waste happens at the household level. The rest comes mostly from food service and retail, the result of inefficient food systems – including production, distribution and consumption. Tackling this issue requires redesigning these systems, transitioning towards a more sustainable, circular approach grounded in efficiency, resilience and sustainability.

For this transition to succeed, we all have a role to play.

Governments can:

  • Advance food waste prevention through climate and biodiversity plans and national policies on circularity, waste, food systems, agriculture and urban development and promote measurement and monitoring. 
  • Strengthen public–private partnerships.
  • Signal leadership and take action by joining the Food Waste Breakthrough.

Businesses can: 

  • Set measurable food waste reduction targets and integrate them into existing sustainability commitments.
  • Innovate to transition to circular food systems and improve efficiency across supply chains.
  • Join the Food Waste Breakthrough to scale solutions and share progress.

Consumers can:

  • Plan, buy, store and prepare food mindfully to cut waste and save resources.
  • Support food recovery, redistribution and composting initiatives.
  • Help make food waste socially unacceptable through everyday action.

A zero-waste future is possible when we all work together – do your part by consuming thoughtfully, recovering surplus food, and working to build circular food systems. Let’s ensure our food is valued, not wasted.

 

 

Background

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. Türkiye, with 105 other countries, put forward the resolution, following other high-level decisions focused on pollution, such as the UN Environment Assembly resolution “End plastic pollution: towards an internationally legally binding instrument”.

The United Nations Environment Programme (UNEP) and the United Nations Human Settlements Programme (UN-Habitat) jointly facilitate the observance of International Day of Zero Waste.

As part of this campaign, Member States, organizations of the United Nations system, civil society, the private sector, academia, women, youth and other stakeholders are invited to engage in activities aimed at raising awareness of national, subnational, regional and local zero-waste initiatives and their contribution to achieving sustainable development.

Promoting zero-waste initiatives through this international day can help advance all the goals and targets in the 2030 Agenda for Sustainable Development, including Sustainable Development Goal 11 and Sustainable Development Goal 12. These goals address all forms of waste, including food loss and waste, natural resource extraction and electronic waste.

Did you know?

  • If packed into standard shipping containers placed end-to-end, the total amount of municipal solid waste we generate each year would be enough to wrap around the globe 25 times.
  • Our increasing use of resources is the main driver of the triple planetary crisis of climate change, nature and biodiversity loss, and pollution.
  • Without urgent action, municipal solid waste generation will balloon to 3.8 billion tons annually by 2050.
  • Most food waste happens within households (60%), followed by food service (28%) and retail (12%).
  • Food loss and waste generate 8-10% of global greenhouse gas emissions, nearly five times the emissions from the aviation industry.

The Food Waste Index

UNEP’s Food Waste Index Report 2021 revealed that there was more food waste data available than anticipated, particularly at the household level, and that per capita household food waste generation was more consistent across countries and cultures than was previously thought. The Food Waste Index Report 2024 incorporates vastly expanded data points from around the world and offers enhanced guidance on measurement across retail, food service, and household sectors.

Habits can change. Here are some easy things you can do to be a Food Hero and make not wasting food a way of life.  FAO also offers new ideas to plan a sustainable next holiday by avoiding over-eating and food waste, as well as a poster to print and decorate your fridge to help your family understand our goals.

International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
