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.
