How the world wastes an astonishing amount of food, in three charts

A recent UN report highlights how over a trillion dollars' worth of food is wasted annually, exacerbating climate change and food insecurity globally.

Sam Delgado reports for Vox.


In short:

  • The UN's 2024 Food Waste Index found that more than 780 million people were hungry in 2022, despite vast amounts of food being wasted.
  • Food waste contributes up to 10% of global greenhouse gas emissions, worsening climate change.
  • Solutions to food waste require coordinated efforts from governments, businesses, and individuals alike.

Key quote:

Food waste reduction is "an opportunity to reduce costs and to tackle some of the biggest environmental and social issues of our time: fighting climate change and addressing food insecurity."

— Report authors

Why this matters:

Food waste not only worsens global hunger but also significantly impacts the environment, making it crucial to address this issue to reduce greenhouse gas emissions and ensure equitable food distribution.
