Harvester's parent, Mitchells & Butlers, has SBTi-validated net-zero targets and renewable electricity across 1,726 sites, but absolute emissions progress is modest at 16% towards a 2040 goal. Critical gaps: no water strategy despite significant consumption, weak biodiversity disclosure, and Scope 3 targets below 1.5°C alignment. Waste and energy programmes are solid but do not offset weak supply chain and nature accountability.
Harvester scores 48/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified May 2026.
