Deep dives
The Scale of Food Waste
Food waste poses a significant environmental challenge, impacting both the planet and global hunger. Annually, one billion meals are wasted each day, equating to over $1 trillion lost. The waste produced has a greenhouse gas footprint five times larger than that of the aviation industry, largely due to methane emissions from landfills where food decomposes. Additionally, the resources used to produce discarded food—such as water and energy—are enormous, and with future food demands expected to rise, utilizing existing food more efficiently is crucial.
