Our verdict

Boohoo operates a linear fast-fashion model with minimal sustainability substance. Zero water data despite supply chain water intensity, no verified emissions targets, and greenwashing investigations underway. Recent declines in emissions track business contraction, not decarbonization strategy.

Boohoo scores 18/100 (Significant gaps) 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 Boohoo joint 912th of 934 companies scored, and 13th of 18 in Apparel (Fast Fashion).
