Sustainability Score
45%
While TheCostumer.com has made recent efforts to reduce packaging waste and introduce some recycled materials, their overall sustainability practices need significant improvement. The company lacks transparency about their supply chain and manufacturing processes. Their labor practices information is limited, and they have not published comprehensive ESG goals. While they have eliminated fur from their products, they still use various synthetic materials with high environmental impact. Their carbon footprint reduction plan is in early stages and lacks concrete targets.
