Extended Data Fig. 1: Likely food waste diversion potential across US states (2022) arranged hierarchically based on the EPA’s original (A) and revised (B) food waste definition.

The green line corresponds to the federal food waste reduction goal (74 kg per capita) by 2030. Coloured segments represent the likely range for the baseline scenario, while additional solutions modelled in the alternative scenario are depicted as black lines. Blue segments represent diversion pathways as originally defined by the EPA (EPA-2016), while green segments reflect the updated definition (EPA-2016), which excludes recycling. The left panel is identical to Fig. 2a, with additional shading to facilitate visualization and comparison.
