Managing retail food waste and markdowns – KEY FACTS

• One-third of global food production is lost or wasted annually
• 0.5-point waste reduction can increase profits by 17%
• Chasing higher on-shelf availability causes food waste to rise sharply
• Adding one day of shelf life cuts food waste by 43%
• Smaller case packs can reduce retail food waste by one-third
• Improving store execution alone could reduce food waste by 48%

One-third of all food is lost or wasted globally

Around one-third of all food produced worldwide is lost or wasted between farm and fork. That’s equivalent to 1.3 billion tonnes every year.

The estimated economic cost is €856 billion annually.

Retail is only one part of this system, but its role is pivotal: small improvements at the retail stage ripple all the way back through supply chains and forward to households.

Cutting retail food waste by 0.5 points can lift profits by 17%

The report shows how powerful small changes can be. If a retailer reduces food waste from 2.0% of sales to 1.5%, a business operating on a 3% net margin can increase net income by 17%.

Waste reduction is not a sustainability “nice-to-have”, it is one of the fastest routes to boosting profits.

Pursuing perfect availability drives waste up fast

Food waste rises sharply as retailers chase ever-higher on-shelf availability. In an idealised system, waste already reaches 2.6% at 95% availability.

And it increases exponentially beyond that point.

This reframes waste as a strategic trade-off. Decisions about availability targets directly shape how much food is thrown away.

One extra day of shelf life can cut waste by 43%

Shelf life is one of the most powerful levers retailers have. Extending product life by just one day reduces waste by 42.8%, while simultaneously improving availability by 3.4%.

Few interventions deliver such large gains with such a small operational change.

Smaller case packs can reduce waste by one-third

Changing how products are shipped also matters. Breaking cases at the distribution centre and sending smaller quantities to stores cuts waste by 32.5%, while improving availability by 2.0%.

Packaging and replenishment design quietly shape waste outcomes far more than most retailers realise.

Better store execution alone could halve food waste

The study finds that improving store-level replenishment and execution could reduce food waste by an average of 48%, even without changing demand or product mix.

Performance varies dramatically: the worst-performing stores generate 72% more waste than benchmark, while the best are only 17% above it.

This shows the vast, untapped potential inside existing operations.
