Supplier Responsibility

At Trinseo, we hold our suppliers to the highest criteria of business conduct and supplier standards through policies, contractual provisions, and supplier assessment and selection processes that meet comparable environmental, social, and governance (ESG) requirements.

We want to partner with like-minded businesses that are driven to reduce their impact on the environment and community, requiring stringent ethical considerations for people throughout the value chain process.

Procurement activities are to be conducted with integrity and care for the health and safety of our customers, suppliers, employees, and communities and for the protection of the environment. Furthermore, our procurement team strives to maintain a sound business relationship with our suppliers, aiming for mutual growth, encouraging innovation, and adopting a culture of continuous improvement.

Supplier Responsibility is just one part of our Sustainability Goals, which together will help us achieve a more sustainable future for our company and the communities we serve.

Our Sustainability Goals

Supplier Responsibility extends our commitments to our suppliers, vendors, and value chain partners to deliver a positive impact beyond the communities we serve.

We continue to utilize integrated third-party sustainability ratings and supplier risk intelligence platforms, incorporating additional due diligence angles such as cybersecurity and financials. As part of the due diligence program, we leverage a Third Party Security Risk Management (TPSRM) process to evaluate and review security controls for new suppliers that host or have access to Trinseo data.

After meeting our original goal of new A-suppliers with an estimated spend of $100,000 or more or those supporting our battery business undergoing due diligence in 2024, we enhanced this goal to maintain 100% of new A-suppliers participating in the Sustainability /CSR Due Diligence programs.

While we are making progress against this goal, the financial aspect of opting into the business sustainability ratings provider was reported as one of the biggest challenges faced by Trinseo’s suppliers in not meeting this goal.
