Sustainability Score
45%
Sister Jane shows limited transparency regarding their sustainability practices and supply chain. While they have introduced some eco-friendly materials in recent collections, they lack comprehensive environmental policies and clear animal welfare guidelines. Their labor practices information is minimal, and they don't publish detailed ESG reports. The brand has made small steps toward sustainability but needs significant improvement in transparency and concrete action plans.
