Billions Wasted: Food Loss Fuels Global Hunger
8 Apr
Summary
- Nearly one-fifth of all available food is wasted globally each day.
- Food loss and waste generate up to 10% of global greenhouse gas emissions.
- Reducing food waste is the most cost-effective climate solution.

Globally, nearly one-fifth of all food is wasted daily, equating to around one billion meals, while close to 800 million people experience hunger. An additional 13% of food is lost post-harvest due to issues in storage, transport, and distribution.
Food loss and waste contribute significantly to climate change, generating up to 10% of global greenhouse gas emissions—five times that of aviation. This waste also squanders vital resources, including land, water, and energy, and puts immense pressure on ecosystems.
Adopting zero-waste strategies is crucial for maximizing food utilization and combating food insecurity. These approaches foster a circular economy, emphasizing waste prevention and repurposing food, which creates jobs and financial benefits.
Implementing practical solutions, from improved farming infrastructure and supply chain efficiency to changes in household habits like meal planning and proper storage, is key. Composting and repurposing waste further contribute to a circular system.
Waste, particularly food waste, is recognized as a critical climate issue, directly impacting daily life through hunger, water shortages, and health concerns. A zero-waste approach offers a practical and immediate pathway for climate action.
