The latest annual impact report from the Global Foodbanking Network – a nonprofit that works with regional food banks in more than 50 countries to fight hunger – shows that its member organisations provided 1.7 billion meals to more than 40 million people in 2023. According to the nonprofit, this food redistribution, much of which was recovered from farms or wholesale produce markets, mitigated an estimated 1.8 million metric tonnes of carbon dioxide equivalent.

These numbers reflect an ongoing, high demand for food banks. Last year, the Global Foodbanking Network served almost as many people as it did in 2020 when the Covid-19 pandemic sent food insecurity soaring. Many of the Global Foodbanking Network’s member organisations have invested in agricultural recovery to respond to this pressing need in their communities, working to rescue food from farmers before it gets thrown out.

Their efforts show how food banks can serve the dual purpose of addressing hunger and protecting the environment. By intercepting perfectly good, edible food before it winds up in the landfill, food banks help mitigate harmful greenhouse gas emissions created by food loss and waste.

“There is always food that is unnecessarily wasted,” said Emily Broad Leib, the founding director of the Food Law and Policy Clinic at Harvard Law School, who has worked with Global Foodbanking Network before but was not involved in the recent study. All that unnecessary waste means “there is an ongoing need for scaling up food banks and food-recovery operations,” Broad Leib added.

A recent United Nations Environment Programme analysis estimated that 13% of food was lost from producers to retailers in 2022. Subsequently, 19% was wasted by retailers, restaurants, and households. The world’s households alone let 1 billion meals go to waste daily. The scope of food wasted around the world has been shockingly high for years: in 2011, the Food and Agricultural Organization of the United Nations released a study that suggested roughly one-third of food produced globally is never eaten.

Food waste at this scale comes with massive planetary impacts. When food goes uneaten, all the emissions associated with growing, transporting, and processing it are rendered unnecessary.

Furthermore, when food rots in landfills, it emits methane, a greenhouse gas roughly 80 times more potent than CO2 over 20 years. Last year, the Environmental Protection Agency reported that 58% of methane emissions from US landfills come from food waste. Globally, food loss and waste have been estimated to be responsible for 8%-10% of greenhouse gas emissions, and reducing them is essential for achieving climate targets.

Food banks can play a special role in that reduction by rescuing more food before it’s lost and redirecting it to people in need.

“Our members have been building out their redistribution capacity,” said Lisa Moon, the president and chief executive of Global Foodbanking Network. “I think that was our first challenge in the face of this rising need: How do we as an organisation capture more supply?”

To do this, food banks within Global Foodbanking Network member organisations have been coordinating more closely with farmers to redirect surplus food from landfills. The Global Foodbanking Network defines surplus food as food from commercial streams grown for human consumption that cannot be sold for some reason. So-called “ugly” produce – misshapen food that never makes it to the grocery store because of its looks – falls into this category.

Some of this redirection actually looks like cutting out food banks as the middleman. Moon gives the example of a food bank that receives a call from a farmer with excess green beans. Instead of traveling to the farm to pick them up, traveling back to the food bank’s distribution hub, storing the green beans, and having folks wait for the next distribution day to collect them, the food bank in question might simply reach out to beneficiaries in the area (think: soup kitchens) to inform them of how many green beans are available and where so they can pick them up. Global Foodbanking Network refers to this as “virtual food banking” because members use tech platforms to match farmers with beneficiaries rather than physically moving the produce themselves.

This emphasis on agricultural recovery has resulted in fruit and vegetables now making up the largest portion – 40% – of food redistributed by Global Foodbanking Network members by volume. Moon says the organisation is “just scratching the surface” of possibilities for recovering fresh produce.

To calculate that these efforts mitigated 1.8 million metric tons of carbon dioxide equivalent, Global Foodbanking Network utilised the Food Loss and Waste Protocol developed by the World Resources Institute. This framework considers several things, including where recovered food would have ended up had it not been intercepted from the waste stream. These waste destinations can be landfills but also include animal feed, compost, and anaerobic digesters (a waste management technology that converts organic waste into biogas – but that can come with its own emissions problems).

Moon acknowledged that the Global Foodbanking Network does not know in every case what would happen to the surplus food if it were not rescued by a food bank – but pointed out that most places where the network operates do not have a robust circular economy for food.

Broad Leib, the Harvard Law food policy expert, described the Global Foodbanking Network’s estimate of carbon dioxide equivalent mitigated as “a good proxy for impact.” While other waste destinations are possible, “we also know that the large majority of wasted food globally goes to landfill,” she said. “I think their estimate is likely not far off from actual emissions avoided.”
