The Food Waste Index Report 2024 builds upon its predecessor in three key ways: Firstly, it incorporates vastly expanded data points from around the world, providing a significantly more robust global and national estimates, detailed in Chapter 2 of the main report. Secondly, it expands on the SDG 12.3 food waste measurement methodology introduced in the 2021 report, offering enhanced guidance on measurement across retail, food service, and household sectors. This additional guidance delves into various methodologies, their strengths and limitations, and strategies for prioritising sub-sectors for measurement, as explored in Chapter 3. Lastly, the report transitions from focusing solely on food waste measurement to exploring solutions for food waste reduction. The chapter examines effective approaches to reducing food waste globally, with a spotlight on public-private partnerships in this 2024 report.
