Sustainability Score

62%
While Diono demonstrates commitment to product safety and durability, their sustainability practices show room for improvement. They provide limited transparency about their manufacturing processes and supply chain. Though they use some recycled materials and have implemented packaging reduction initiatives, they lack comprehensive environmental policies and clear carbon reduction goals. Their labor practices documentation is minimal, and they could improve their reporting on factory conditions and worker welfare.
