The Drivers of Food Waste in Europe
Every year, millions of tonnes of food are wasted across Europe. Food waste is not only an ethical issue, but also an emerging environmental, social, and economic concern that pushes us to ask the question – what are the drivers of food waste in Europe?
Within the European Union, different initiatives and policies contribute to our collective understanding and addressing food waste. And while, as a result, public awareness is growing, effectively tackling the problem requires an ever-wider understanding of why food waste occurs in the first place.
In this blog, we do just that for those who are not yet familiar with this issue – we list the key causes of food waste in the EU and beyond. And, as a bonus, we explain why addressing food wasting is essential for building a more sustainable and resilient food system.
Main Drivers of Food Waste
Understanding the key drivers of food waste in Europe is a must for designing and implementing effective and targeted interventions. In Europe, food wasting occurs across all stages of the supply chain and is shaped by a mix of behavioural, structural, and systemic factors.
The main drivers include:
- Consumer Behaviour and Household Habits
- Confusion Around Food Date Labelling
- Hospitality Sector Practices
- Production and Supply Chain Inefficiencies
- Lack of Awareness
Let’s run through them one by one.
Consumer Behaviour and Household Habits
Households generate over half of the food waste in the EU. How many times have you caught yourself buying something just because it was on special offer or discount? The 2024 paper “Exploring the Neuro-Psychological Drivers of Impulse Buying: An Analysis of Marketing Tactics, Ethical Implications, and Demographic Differences” states that “the use of price anchors such as ‘50% off’ often triggers impulsive purchases, despite the item’s original price not aligning with its perceived value.”
Impulsive purchases like these can quickly lead to overstocked fridges and food that ends up going to waste. Another common issue many of us face is dealing with inappropriate portion sizes, oversized packaging, and poor food storage, all of which can lead to food being wasted before it’s ever used.
We can’t ignore how busy life affects our food habits, either. For example, in many households, juggling work, school, and family commitments means meal times can be unpredictable, causing fresh ingredients or leftovers to be overlooked and eventually wasted.
Confusion Around Food Date Labelling
A 2018 study by the European Commission found that up to 10% of annual food waste may be caused by misunderstandings of food date labels. Many people, especially in high-income countries, see a date on a package and think it’s safer to throw the food away and buy a new one rather than risk eating something that might be spoiled.
In the European Union, foods generally carry two types of labels: “best before” and “use by.” The “best before” date refers to when the food is at its best quality, but it is often still safe to eat after this date. The “use by” date, however, is about safety, foods should not be eaten past this date.
Because many consumers don’t fully understand these differences, perfectly good food is frequently discarded too soon. That’s why improving education around food date labels is key to reducing food waste.
Hospitality Sector Practices
The hospitality sector, including restaurants, hotels, and catering services, plays a big role in food waste. One common cause is that kitchens often prepare large amounts of food, or cook more than what’s actually eaten, and the leftovers end up being thrown away.
Portion sizes can also be a problem. Standardised servings might be bigger than what people can finish, leading to uneaten food on plates. Plus, in busy settings, it’s hard to perfectly predict how many customers will show up, so overestimating guest numbers can lead to extra food being prepared and wasted.
On top of that, some places focus on having only the freshest ingredients available, so if a product isn’t used quickly enough, it gets discarded even if it is still safe to eat.
If you, or someone you know, works in the hospitality sector in the EU, look into the EU’s Donation guideline of food surpluses in hospitality industry for charitable purposes. It lists, in detail, which food can be donated, and in which way.
Production and Supply Chain Inefficiencies
Think about the last time you were at the market or grocery store, did you reach for the reddest, biggest, and most perfectly shaped apple? This preference for picture-perfect produce is common, but it creates a big problem in the supply chain. Farmers and suppliers often have to meet strict quality standards, which means that many perfectly good but less visually appealing fruits and vegetables never make it to the shelves and end up being wasted.
Food waste also occurs because of inefficiencies in the supply chain, such as poor storage conditions, transportation delays, or overproduction. Sometimes farmers grow more than needed due to unpredictable demand or contractual obligations, leading to surplus food that goes unused.
When food isn’t handled or transported properly, it can spoil before it even makes it to the store, leading to waste that could have been avoided.
Lack of Awareness
One of the main reasons food waste in Europe continues to be such a big problem is that many people simply aren’t aware of its full impact. People often don’t think about how the way they shop, cook, and eat today affects the environment, the economy, and society as a whole. However, the cost of food waste goes far beyond just one household. When millions of homes throw away uneaten food every day, those losses add up across the entire economy.
There’s also an important social and ethical side to this issue. In some parts of the world, perfectly good food is thrown away because it is not used in time or doesn’t look “perfect,” while in other places, people struggle to get enough to eat. This gap shows how easily we take food for granted. The more consumers understand the environmental, economic, and social consequences of food waste, the more motivated they become to change their habits and make responsible choices every day.
Conclusion
To address the drivers of food waste, more and more initiatives are emerging across Europe. Many of them focus on raising awareness and providing practical tools to help people reduce food waste in their daily lives. One such project is WiseFood, funded by the EU. This three-year initiative takes a comprehensive approach by making reliable data accessible and offering clear recommendations to encourage positive behaviour change.
