B&Q reports strong operational decarbonization (66% since 2016/17) and near-complete renewable electricity (99%), but Scope 3 emissions—99.5% of its footprint—rose 6% last year despite intensity gains. Water impact is entirely unreported. New absolute Scope 3 targets (46% by 2030) shift away from greenwashing metric frames, but delivery remains unproven.
B&Q scores 47/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.
That places B&Q joint 237th of 934 companies scored, and 6th of 50 in Retail (non-fashion).
