Princes reports Scope 1, 2 and 3 emissions, including purchased goods, and has SBTi-validated targets, but its report gives conflicting 2025 figures, none of them assured, and it missed some packaging targets. In October 2025 Blue Marine Foundation and Planet Tracker criticised it for sourcing most of its tuna from fisheries using drifting fish-aggregating devices.
