Sustainability Score
68%
While the company promotes water conservation through their products, their corporate practices show room for improvement. They have basic recycling programs and some renewable energy initiatives, but lack comprehensive sustainability reporting and clear carbon reduction targets. Their supply chain transparency is limited, though they do maintain fair labor standards. Their packaging could be more eco-friendly, and their manufacturing partners' environmental practices aren't fully disclosed.
