Sustainability Score
65%
While COSRX has made steps toward sustainability with some recyclable packaging and cruelty-free certifications, their overall transparency regarding environmental practices and supply chain ethics needs improvement. The company has limited public information about their carbon footprint and labor conditions. Their recent initiatives in reducing plastic usage and implementing more eco-friendly packaging show promise, but they still lag behind industry leaders in comprehensive sustainability reporting and concrete environmental commitments.
