In 2022, over 1 billion tonnes of food waste was produced worldwide—equivalent to around 132 kg per person. Food loss and waste is an urgent global issue with significant social, economic, and environmental implications. According to the United Nations Environment Programme, this represents an economic loss of more than 1 trillion dollars, affecting actors throughout the value chain, from small and large producers to vendors, distributors, and consumers. Outrageously, almost 800 million people suffer from hunger and 15 million children under five years old are malnourished.
Embracing zero waste strategies linked with food systems is not merely an option—it is necessary to achieve significant climate and social benefits for current and future generations. Strong political action is needed to put in motion a pathway to systemically address food loss and waste. The moment to take bold, decisive action is now. Learn how communities work together to prevent food loss and waste through zero waste practices, while reducing methane emissions and keeping global warming below 1.5°C.
