With 783 million people going hungry, a fifth of all food goes to waste

Since food loss and waste generates up to 10 per cent of global greenhouse gas emissions – almost five times the total emissions compared to the aviation sector – reducing emissions from food waste is essential, UNEP expert believe. Published ahead of the International Day of Zero Waste, the UNEP Food Waste Index Report, has been co-authored with WRAP, a UK climate action NGO.Hotter countries appear to have more food waste per capita in households, potentially due to increased consumption of fresh foods containing fewer edible parts and a lack of robust refrigeration and preservation solutions.

‘Global tragedy’

Most of the world’s food waste comes from households, totalling 631 million tonnes – or up to 60 per cent – of the total food squandered. The food service and retail sectors were responsible for 290 and 131 million tonnes accordingly.The report recommends focusing efforts on strengthening food waste reduction and composting in cities. That is in addition to around 13 per cent of food lost in the supply chain, as estimated by the UN Food and Agriculture Organization (FAO), from post-harvest up to the point of sale. 

Not just a ‘rich country’ problem

High-income, upper-middle income, and lower-middle income countries differ in average levels of household food waste by just seven kilogrammes per capita per year. Examples include Japan and the UK with reductions of 18 per cent and 31 per cent respectively, showing that change at scale is possible, if food is rationed properly. The problem is not confined to affluent nations. Following a near doubling of data coverage since the 2021 Food Waste Index Report was published, there has been increased convergence between rich and poor.Some 19 per cent of food available to consumers was lost overall at retail, food service, and household levels.There is a direct correlation between average temperatures and food waste levels, the report finds.

Waste and climate change

On average, each person wastes 79 kilogrammes of food annually. This is the equivalent of 1.3 meals every day for everyone in the world impacted by hunger, the report authors underscore.It provides the most accurate global estimate on food waste at retail and consumer levels, offering countries guidance on improving data collection and best practices, in line with the Sustainable Development Goal 12.3 of halving food waste by 2030.In middle-income countries, for example, rural areas are generally wasting less. One possible explanation is in the recycling of food scraps for pets, animal feed, and home composting in the countryside. Higher seasonal temperatures, extreme heat events, and droughts make it more challenging to store, process, transport, and sell food safely, often leading to a significant volume of food being wasted or lost.

Food for hope

The bigger divide comes in the variations between urban and rural populations.“Food waste is a global tragedy. Millions will go hungry today as food is wasted across the world,” said Inger Andersen, Executive Director of UNEP, explaining that this ongoing issue not only impacts the global economy but also exacerbates climate change, biodiversity loss, and pollution.The UN Environment Programme’s Food Waste Index Report 2024 highlights that latest data from 2022 shows 1.05 billion tonnes of food went to waste.There is room for optimism, the report suggests: public-private partnerships to reduce food waste and impacts on climate and water stress are being embraced by a steadily growing number of governments of all levels.
