Brompton Bicycle scores 51/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Brompton Bicycle joint 120th of 809 companies scored, and joint 3rd of 33 in Electronics / Hardware.
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.
