Sustainability Score
45%
While Diadem Sports offers some eco-friendly products, their overall sustainability practices lack transparency and comprehensive reporting. Their packaging practices show room for improvement, and there's limited information about their supply chain ethics. The company has made some initial steps toward sustainability but lacks clear targets and measurable goals. Their carbon footprint reporting is minimal, and their commitment to fair labor practices needs more documentation.
