In the United States, the Environmental Protection Agency (EPA) estimates that food reached landfills more than any other single material. When food goes to the landfill, it rots and produces methane – a greenhouse gas more potent than carbon dioxide. We could reduce roughly 6%-8% of all human-caused greenhouse gas emissions if we just stopped wasting food. Take our Lunch Food Waste Audit – it’s a two-week project that asks you to track your lunch waste and change some habits. Measure as best you can and take photos. Share your findings and share what you will do differently.
