Food waste vs world hunger: the paradox in numbers

In 2022, households around the world threw away more than a billion meals a day. Over the same period, 645 million people did not have enough to eat, and famines had just been officially declared in Gaza and Sudan. That these two figures exist side by side is the best-documented paradox in our global food system.

This guide sets out the 2026 figures on food waste and explains why waste and hunger exist side by side, against all logic. It also measures the climate impact of food waste and walks through the ways to act, from everyday habits to supporting a charity.

How much food is wasted worldwide every year?

The benchmark figure comes from the Food Waste Index Report 2024 by the United Nations Environment Programme (UNEP), published in March 2024 using 2022 data: 1.05 billion tonnes of food were wasted, including inedible parts.

On a human scale, that means:

• 132 kg for every person on the planet, every year.
• 19% of the food available to consumers.
• More than a billion meals thrown away every day, from households alone.
• 41,200 kg of food thrown away every second around the world.

Add the upstream losses that happen before food reaches shops (in farming, processing, transport and storage) and the FAO puts the total at around 1.3 billion tonnes. That is a third of all the food produced worldwide for people to eat.

Where is food wasted, and by whom?

The geography of waste follows a clear pattern: the more developed a country, the more it wastes downstream. The poorer it is, the more it loses upstream.

Where global food waste comes from (UNEP report 2024)

The 2024 report corrects a common misconception: waste is massive in almost every country, whatever its income. It is not just a rich-country problem. Once cities start to grow, emerging and low-income countries waste almost as much food per person as developed ones.

Spotlight on France: 10 million tonnes a year

In France, the environment agency ADEME puts food waste at around 10 million tonnes a year across all stages, including about 30 kg per person at home. The 2016 Garot law banned food supermarkets larger than 400 m² from throwing away unsold food that is still fit to eat, and required them to partner with charities that receive donations. As a result, French food banks recover more than 250 million meals every year through this scheme.

The paradox: why throw so much away when 645 million people are hungry?

The contrast is stark: 1.05 billion tonnes wasted against 645 million undernourished people. Converted into calories, the world's annual food waste could in theory feed everyone who is hungry several times over.

So why doesn't this happen? There are three structural reasons.

The food thrown away is in the wrong place. Most of it is wasted in homes in rich countries or in urban supply chains. Hunger is concentrated in rural areas of countries at war, which have no logistics infrastructure to receive that food, even if it were redirected.

Recovering food often costs more than the food is worth. Sorting, transporting, chilling and redistributing unsold food is expensive. To make economic sense, redistribution has to be local and fast, which automatically rules out part of the supply.

The market is built for production, not for fair distribution. The world produces 4,600 kilocalories per person per day, easily enough to feed 12 billion people. The challenge is not to produce more but to distribute better. Our in-depth analysis, food insecurity: causes and lasting solutions, looks at this in detail.

What is the environmental impact of food waste?

Beyond the human paradox, food waste is an environmental disaster, and one we can measure.

UNEP estimates that food loss and waste generate 8 to 10% of global greenhouse gas emissions, more than the entire global aviation sector. The FAO goes further: if food waste were a country, it would be the world's third-largest emitter, after China and the United States.

The main culprit is methane, released when food waste rots without oxygen in landfill. According to the IPCC, this gas is around 80 times more potent than CO₂ over a 20-year period.

On top of this come the resources used upstream to produce food that is never eaten:

• The fresh water needed for farming, much of it already scarce in dry regions.
• Farmland used for nothing, often at the cost of deforestation.
• The energy used to process, transport, chill and package food.

What is being done worldwide to tackle food waste?

Sustainable Development Goal target 12.3 sets the course: halve global food waste per person by 2030 at retail and consumer level, and reduce losses along supply chains. All signatory states are committed to this target.

On the ground, three types of action work together.

National public policy. France's 2016 Garot law was a pioneering example: a ban on throwing away unsold food, compulsory partnerships with charities and fines for anyone who doesn't comply. Since then, Italy, Spain and several US states have brought in similar schemes.

Innovation from businesses and charities. Apps selling unsold food at bargain prices (Too Good To Go, Phenix), platforms for sharing food between neighbours (Olio), AI stock forecasting for supermarkets: tech has moved into this area in a big way since 2015.

International programmes. The WFP (World Food Programme), the FAO through its Save Food initiative, and UNEP run programmes focused on post-harvest losses in the Global South: airtight silos, solar-powered cold chains and training for smallholder farmers.

Bridging waste and hunger: what humanitarian NGOs do

A humanitarian NGO like LIFE plays a specific role here. It doesn't physically collect unsold food from French households. Instead, it uses efficient logistics and local purchasing to bring the cost of a meal down to one euro.

Buying locally avoids losses in transport. When LIFE buys rice in Cambodia or chickpeas in Lebanon for its distributions, it shortens the supply chain, cutting both emissions and losses in transit.

Targeted distribution makes sure food is used. Distributions are based on careful needs assessments, so nothing is left over to go to waste. Every kilo handed out is eaten.

Supporting food sovereignty tackles the root cause. Training farmers, handing out hardy seeds and building wells for irrigation give local communities the means to grow their own food, with fewer losses after harvest. Our dedicated article on food sovereignty covers this in full.

How can you cut food waste yourself?

At home, a few simple habits are enough to cut household food waste by 30 to 50%.

Plan your meals and shopping. Writing a shopping list based on a weekly menu stops you buying too much and ending up with extras that go off in the fridge.

Understand date labels. The DDM (minimum durability date, formerly DLUO), similar to a 'best before' date, is not a deadline for eating: it shows when the food is at its best. The DLC (use-by date) on fresh products is stricter, but often still includes a safety margin.

Store food properly. Keep fruit and veg that don't like the cold (tomatoes, bananas) out of the fridge, put fresh products in the right part of the fridge, and always freeze leftovers.

Cook with leftovers. A soup to use up tired vegetables, a savoury loaf to use up leftover protein, a mixed salad to finish everything off: the most effective everyday way to fight waste.

Use anti-waste apps. Too Good To Go and Phenix let you buy local shops' unsold food at reduced prices, saving several million meals a year in France.

Support NGOs that make food aid go further. A donation to a charity such as LIFE or the Restos du Cœur directly funds distributions with very little waste, which by design are far more effective than anything an individual could redistribute.
