International Day of Zero Waste – Tackling Food Waste
On 30 March, we observe the International Day of Zero Waste. A day on which the United Nations calls on everyone to reflect on the enormous amount of waste we produce worldwide – and what we can do about it. In 2026, one theme takes centre stage: food waste. A topic that is not only relevant for governments and large organisations, but just as important for you as an entrepreneur. Food waste affects the planet, the economy, and the long‑term resilience of your business. If you want to take steps towards less waste, more efficiency and a more sustainable way of working, this is the perfect moment to start.
What is the theme of International Day of Zero Waste 2026?
The theme for Zero Waste Day 2026 is Food. Food waste happens on a much larger scale than most people realise. According to the United Nations:
- Every year, 1 billion tonnes of edible food is wasted.
- That is around 20% of all available food.
- 60% of food waste happens in households, but businesses also play a major role.
- Food waste accounts for 10% of global CO₂ emissions – five times more than the aviation sector.

Zero Food Waste Day
On 14 December 2022, during its 77th session, the United Nations General Assembly adopted a resolution to declare 30 March as the International Day of Zero Waste, to be observed annually.
Türkiye, together with 105 other countries, introduced the resolution, following earlier high‑level decisions aimed at tackling pollution – such as the UN Environment Assembly resolution “End plastic pollution: towards an internationally legally binding instrument.”
What are the 7 R’s of Zero Waste?
This day is about awareness, but even more about action. The 7 R’s of Zero Waste help you apply this step by step within your business:
- Rethink – Rethink your processes: where does waste arise?
- Refuse – Refuse products that create unnecessary waste.
- Reduce – Reduce your use of resources, energy and food.
- Reuse – Give materials and products a second life.
- Repair – Repair instead of replace.
- Regift – Donate or share what you no longer use.
- Recycle – Ensure materials are processed for reuse.
These simple steps help you make waste visible and manageable.
Food waste in businesses
Food loss and waste are a major threat to the climate and the environment. They are responsible for up to 10% of global greenhouse gas emissions — almost five times more than the aviation sector — and up to 14% of global methane emissions.
Reducing food waste is one of the most cost‑effective and achievable climate solutions. It aligns perfectly with a zero‑waste approach focused on prevention, resource efficiency and systemic change.
Governments, businesses and individuals must embrace this zero‑waste mindset to successfully tackle the waste and pollution crisis. For many companies, the biggest opportunity lies in rethinking how they handle food.
Your business can apply this easily too. A good starting point is gaining insight into your environmental impact.
What can you do today? Small steps, big impact
Working more sustainably does not have to be complicated. Businesses can set measurable food‑waste goals, innovate towards circular food systems and share progress. Begin with small actions that deliver immediate results:
✔️ Reduce food waste
- Order more efficiently for your company canteen or lunchroom.
- Use an app like Too Good To Go.
- Offer smaller portions or flexible menus.
✔️ Encourage reuse
- Set up a collection point for clothing or materials.
- Donate usable products to local initiatives.
✔️ Choose circular suppliers
- Think about LED lighting, circular coffee suppliers or refurbished equipment.
✔️ Improve your insights
- Map your CO₂ emissions, waste streams and environmental performance.
- Make sustainability simple and achievable with clear goals.
Zero Waste and the CSRD
Working sustainably is not only good for the planet – it is also increasingly required. Especially with the arrival of CSRD.
This legislation requires companies to report on their:
- Environmental impact (including waste)
- Social responsibility
- Governance structure
Food waste and waste streams fall directly under these reporting obligations. The earlier you start, the easier your reporting will be.
Towards a zero‑waste future – start today
The UN highlights that everyone plays a role in fighting food waste:
- Governments develop policies and stimulate circular initiatives.
- Businesses set concrete goals and modernise their processes.
- Consumers make conscious everyday choices.
As an entrepreneur, you don’t have to do this alone. With the right tools you can gain immediate insight, report more efficiently and improve your impact step by step.
