4PLANET IMPACT / ISSUE

Food waste

Food discarded after land, water, energy and labour have already been used creates avoidable environmental and economic pressure.

Why it matters

Food-waste reduction requires measurement of actual waste and behaviour; assumed savings are not demonstrated outcomes.

What the sources establish

UNEP's Food Waste Index Report 2024 measures food waste across retail, food service and households and provides guidance for tracking reduction.
