The United Nations Environment Programme published the 2021 Food Waste Index report on the 4th of March 2021.
The Food Waste Index Report aims to supporting the goals of SDG 12.3. It does so by presenting the most comprehensive food waste data collection, analysis and modelling to date, generating a new estimate of global food waste; and publishing a methodology for countries to measure food waste, at household, food service and retail level, to track national progress towards 2030 and to report on SDG 12.3. Countries using this methodology will generate strong evidence to guide a national strategy on food waste prevention, that is sufficiently sensitive to pick up changes in food waste over two- or four-year intervals, and that enables meaningful comparisons between countries globally.
