Grievance procedure for natural rubber supply chain

The Bridgestone Group believes all stakeholders throughout its natural rubber supply chain play a constructive role in improving its sustainability. To support implementation of our Global Sustainable Procurement Policy, the Group is committed to managing a grievance mechanism which allows stakeholders to raise grievances related to its policy. The Group is committed to an open and transparent process where all grievances will be dealt with fairly and in a timely manner. Results of this process will be publicly disclosed.

The Bridgestone grievance mechanism will align with the United Nations Guiding Principles on Business and Human Rights criteria for effective and non-judicial grievance mechanisms: legitimacy, accessibility, predictability, equitability, transparency, rights-compatible, a source of continuous learning, and based on engagement and dialogue.

Bridgestone’s grievance mechanism serves as a guide to review, address, and monitor the outcome of any grievance from any external stakeholder concerning the Global Sustainable Procurement Policy across Bridgestone’s global supply chain.

To address non-compliances, Bridgestone will support upstream engagement with natural rubber supply chain actors and collaborate in industry efforts aimed at addressing social and environmental issues in rubber supply chain.
