Sustainability Score
52%
While Onepiece has made some efforts toward sustainability with organic cotton options and recycled packaging, they lack transparency in their supply chain and manufacturing processes. Their labor practices information is limited, and they don't have clear animal welfare policies. The company has basic environmental initiatives but falls short on comprehensive sustainability reporting and concrete emission reduction targets. Their moderate efforts are overshadowed by insufficient disclosure and limited commitment to industry-leading sustainable practices.
