Brompton has built credible climate governance and waste reduction programmes backed by B Corp certification, but its emissions trajectory worsened in FY2024 due to e-bike mix and air freight. Supply chain dominates footprint at 97%, yet Scope 3 targets remain intensity-based rather than absolute. A controversial new factory approved over Kent Wildlife Trust objections signals unresolved nature risks.
