European households discard more than 70kg of food per person each year, according to a new analysis by Professor Ian Williams of applied environmental science. Based on average waste levels across the EU and the United Kingdom, the study estimates that 69 million tonnes of food were wasted in Europe in 2025.
Globally, the scale of the problem is even greater. In 2022, the most recent year with available data, households, retailers and food services wasted more than one-billion tonnes of food.
The issue goes beyond economics. While a family of four could save around €400 annually by reducing food waste, the impact also extends to lost resources and increasing environmental pressure.
Why households waste so much food
The main drivers of food waste are behavioural. A lack of awareness, combined with health concerns about food considered “expired,” often leads people to throw away edible items. These tendencies are reinforced by modern lifestyles that prioritise convenience.
Shopping habits play a central role. Promotions such as “buy one get one free” or “three for two” encourage over-purchasing, while time pressure and shopping while hungry make matters worse. Consumers who plan meals and shop with a list tend to waste significantly less.
Retail design also contributes to the problem. Large packaging sizes and limited options for smaller portions mean single-person households often buy more than they can consume. Discounts on products nearing their expiry date can help, but only if shoppers plan to use or freeze them.
Confusion over date labels is another key factor. Many consumers treat “best before” dates as strict safety limits, leading them to discard food unnecessarily. Clearer labelling could sharply reduce this waste.
Storage and everyday habits matter
Once food reaches the home, daily management becomes critical. Simple techniques can make a significant difference.
Freezing, batch cooking and the “first in, first out” method, meaning older items are used before newer ones, can dramatically cut spoilage. Frozen food is wasted far less than fresh produce, underlining the importance of basic storage skills.
However, modern lifestyles complicate meal planning. Busy schedules and reliance on ready meals increase waste, while social norms around hospitality and abundance often lead households to prepare more food than needed.
Income alone does not explain the pattern. The study found no consistent link between national GDP and household food waste levels, suggesting that local habits, tourism and consumer behaviour are more decisive factors.
The role of supermarkets and policy
Food waste is not limited to households. Large volumes of safe, edible food are also discarded by supermarkets and food businesses.
Some countries have introduced targeted measures. France, for example, requires supermarkets to donate unsold food rather than destroy it. The law reduces legal liability for retailers and encourages donations to charities and food banks. It also bans the deliberate destruction of edible products and promotes education on food waste in schools and workplaces.
Such policies can help reduce waste, support vulnerable groups and strengthen social cohesion. However, experts warn that long-term solutions must go beyond charity and ensure equitable access to quality food for all.
Practical steps to cut waste
The study outlines three key areas for action:
- Improve communication by standardising date labels and running public awareness campaigns so consumers understand the difference between quality and safety
- Reform retail practices by promoting smaller packaging, resealable formats and clearer pricing for products nearing expiry, as well as encouraging the sale of imperfect produce
- Support households through cooking education, food management campaigns and simple digital tools that help track supplies at home
No single policy will solve the problem. Effective action requires a combination of retail reform, clear regulation and consumer support, tailored to local cultures and household habits.
Small changes at home, including better planning, smarter shopping and improved storage, can deliver significant benefits for both household budgets and the environment.
The next step is clear. Policies must work where people live, shop and cook. Reducing food waste will not only cut costs and emissions, but also strengthen food security across Europe.
The solutions already exist and can be implemented at scale.
