One-third of all food produced is either lost or wasted. According to UNEP’s Food Waste Index Report 2021, people globally waste 1 billion tonnes of food each year, which accounts for around 8-10 percent of global greenhouse gas emissions.

When you throw food away, you're also wasting the resources and energy that were used to grow, produce, package, and transport it. And when food rots in a landfill, it produces methane, a powerful greenhouse gas. So use what you buy and compost any leftovers.
