In July, Project Drawdown released a major update to its  2017 analysis of how the global community can implement currently available and readily scalable solutions to avoid the most catastrophic effects of climate change. The report ranks food waste reduction as the #1 solution under the scenario that limits end-of-century warming to 2°C. If we target limiting warming to 1.5°C, reducing food waste comes in at #4, just after a plant-rich diet.

It takes a tremendous amount of energy to grow, process, package, store, and transport the food we bring into our homes. Making sure you purchase and prepare the right amount of food, use up leftovers, and compost food scraps is an important climate action.
