The correct answer is United Nations Environment Programme. Explanation & Key Takeaways: • The Food Waste Index (FWI) Report is released by the United Nations Environment Programme (UNEP). • The report aims to measure food waste at household, retail, and food service levels globally. • It provides insights into the scale of food waste and encourages nations to take action to reduce it. • The FWI report contributes to achieving Sustainable Development Goal (SDG) 12.3, which focuses on halving global food waste by 2030. Related Concepts: • Food and Agriculture Organisation (FAO): The FAO is a specialized agency of the United Nations that leads international efforts to combat hunger and improve agricultural practices. While FAO deals with food security and agricultural issues, the Food Waste Index is not its report. • United Nations Agricultural Programme (UNAP): There is no specific program called "United Nations Agricultural Programme." This option may have been included erroneously or as a distractor. • Intergovernmental Panel on Climate Change (IPCC): The IPCC is an international body for assessing climate change science. It provides comprehensive reports on climate change impacts, mitigation, and adaptation but does not release the Food Waste Index Report.
