UN report highlights global food waste crisis

A recent report from the United Nations Environment Programme (UNEP) sheds light on the alarming magnitude of food waste worldwide.

In 2022, households across all continents squandered over 1 billion meals daily, while 783 million people endured hunger, and a third of the global population faced food insecurity.

The ramifications of this waste extend beyond mere inefficiency, impacting the global economy and exacerbating climate change, biodiversity loss, and pollution.

Published ahead of the International Day of Zero Waste, the UNEP Food Waste Index Report 2024, co-authored with WRAP, presents meticulous estimates of food waste at both retail and consumer levels, offering guidance for countries to enhance data collection and adopt best practices for waste reduction.

In 2022, the world generated 1.05 billion tonnes of food waste, equivalent to 132 kilograms per capita and nearly one-fifth of all food available to consumers.

Notably, 60% of this waste occurred at the household level, with food services and retail accounting for 28% and 12%, respectively.

Inger Andersen, Executive Director of UNEP, lamented the global tragedy of food waste, emphasizing its developmental, environmental, and economic toll.

However, she expressed optimism, highlighting the potential for significant progress if countries prioritize waste reduction efforts.

While data infrastructure has improved since 2021, many low- and middle-income countries still lack adequate systems for monitoring progress toward Sustainable Development Goal 12.3, which aims to halve food waste by 2030.

Only a handful of G20 countries, alongside the European Union, possess suitable estimates for tracking progress.

Contrary to the perception of food waste as a problem exclusive to affluent nations, the report reveals marginal differences in household waste levels across income brackets.

Moreover, regions with hotter climates tend to exhibit higher per capita waste, possibly due to greater consumption of perishable foods and insufficient cold chain infrastructure.

The report underscores the substantial environmental impact of food waste, contributing 8-10% of global greenhouse gas emissions and occupying a third of the world’s agricultural land.

Additionally, the economic toll amounts to approximately USD 1 trillion annually.

Efforts to combat food waste offer substantial benefits, particularly in urban areas, where waste reduction initiatives can yield significant dividends.

Despite challenges, countries like Japan and the UK have demonstrated that ambitious reductions are achievable through policy implementation and partnerships.

Harriet Lamb, CEO of WRAP, echoed the call for concerted action, emphasizing the necessity of greater collaboration across sectors and regions.

Public-Private Partnerships (PPPs) emerge as a crucial tool for effecting change, offering avenues for innovation, knowledge sharing, and sustainable financing.

As countries strive to meet ambitious climate and development goals, addressing food waste emerges as a pressing imperative.

By fostering partnerships and implementing targeted strategies, the global community can mitigate the adverse effects of food waste while advancing towards a more sustainable future.
