Global food waste: 1 billion tons yearly impact
30 Mar
Summary
- Over one billion tonnes of edible food is wasted annually.
- Food waste costs the global economy an estimated $1 trillion yearly.
- Food waste contributes 8-10% of global greenhouse gas emissions.
The world is facing a critical challenge with over one billion tonnes of edible food wasted annually, representing nearly a fifth of all food available to consumers. This immense waste, observed during the recent 'International Day of Zero Waste', has profound implications for food security and climate resilience. The United Nations Environment Programme (UNEP) highlights that this discarded food incurs an annual cost of $1 trillion to the global economy.
A significant portion, 13% of food, is lost before it reaches retailers, with households being major contributors to waste. Globally, an estimated 1.05 billion tonnes of food were wasted in 2022, averaging 132 kg per person, with households responsible for 79 kg of this. This waste generates 8-10% of global greenhouse gas emissions, primarily methane, a potent greenhouse gas.
Effective solutions involve redesigning food systems towards sustainability and circularity. Governments can implement national policies on waste and food systems, while businesses can set reduction targets and innovate supply chains. Consumer behavior change campaigns and food literacy programs are also crucial. Organic waste, if treated and composted, can be a valuable resource for soil health, reducing reliance on fertilizers.
