In 2022, households worldwide discarded a staggering one billion meals daily, marking what the United Nations termed a “global tragedy” of food wastage.
The UN’s latest Food Waste Index Report, released on Wednesday, highlighted the disposal of over $1 trillion worth of food by households and businesses, amid nearly 800 million people experiencing hunger.
This report revealed that over 1 billion tonnes of food—almost one-fifth of the total available—was squandered in 2022, with households being the primary contributors.
Inger Andersen, executive director of the UN Environment Programme lamented, “Food waste is a global tragedy. Millions go hungry daily as food is wasted across the globe.”
Described as not just a moral but an “environmental failure,” food waste generates five times more planet-heating emissions than the aviation sector and necessitates vast land conversion for growing unconsumed crops.
Co-authored with the non-profit organization WRAP, this report marks the second UN compilation on global food waste, offering the most comprehensive insight to date. Improved data collection has underscored the true extent of the problem, as noted by Clementine O’Connor from UNEP: “The more food waste you look for, the more that you find.”
While the reported “billion meals” discarded is deemed a “very conservative estimate,” the actual figure could be considerably higher, emphasizing the urgency of the issue.
Richard Swannell from WRAP expressed astonishment at the magnitude of waste, highlighting that the annual discarded food could feed approximately 800 million hungry people daily.
Efforts to reduce waste and redirect surplus food to those in need have been underway through collaboration between producers and retailers. However, more concerted action is necessary.
Notably, households accounted for 60 percent of the approximately 631 million tonnes wasted in 2022. Reasons for this include over-purchasing, miscalculating portion sizes, and discarding leftovers prematurely due to misconceptions about expiration dates.
Additionally, inefficiencies in transportation and lack of refrigeration contribute to food loss, especially in developing regions.
Contrary to assumptions, food waste is not confined to affluent nations and is prevalent worldwide, with hotter climates often correlating with higher waste rates.
Businesses often underestimate the financial impact of food waste, opting for landfill disposal due to low disposal costs.
The consequences of food waste are profound, impacting both people and the planet. Wasted land and greenhouse gas emissions exacerbate habitat loss and climate change.
Swannell emphasized the urgent need for collective action to reduce food waste across the supply chain, underscoring the opportunity to mitigate environmental harm and save resources.
In closing, he emphasized that addressing food waste is paramount in reducing greenhouse gas emissions and conserving resources, urging global attention and concerted efforts toward this critical issue.
