Sustainability Score
61%
Master Lock shows mixed performance in sustainability practices. While they have implemented some energy-efficient manufacturing processes and have policies for responsible sourcing, their transparency regarding environmental impact and detailed ESG reporting is limited. The company has basic worker protection policies but could improve their supply chain oversight. Their environmental initiatives, while present, lack aggressive targets for carbon reduction. The company's minimal public disclosure of sustainability metrics and moderate pace of implementing green initiatives affects their overall rating.
