Back Market's business model delivers inherent circularity benefits—refurbished electronics avoid 91% of raw materials and 89% of e-waste versus new production. But the company discloses almost no operational emissions data, lacks binding reduction targets, and shows no formal Scope 1, 2, or 3 quantification. Growth at 30%+ annually makes absent emissions trajectory tracking a material gap.
Back Market scores 43/100 (Below expectations) 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 Back Market joint 331st of 934 companies scored, and joint 15th of 24 in E-commerce / Online Retail.
