The Food Loss and Waste Accounting and Reporting Standard (or FLW Standard) is a global standard that provides requirements and guidance for quantifying and reporting on the weight of food and/or associated inedible parts removed from the food supply chain—commonly referred to as “food loss and waste” (FLW). Using the standard enables countries, cities, companies, and other entities to develop inventories of how much FLW is generate dand where it goes. These inventories can underpin, inform, and focus strategies for minimizing FLW. Minimizing FLW can provide economic benefits, enhance food security, improve natural resource use efficiency, and reduce environmental impacts.
