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 2030 Sustainability Goals, which together will help us achieve a more sustainable future for our company and the communities we serve.

2030 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.

Trinseo continues to evaluate suppliers against policies and procedures such as our Supplier Code of Conduct and Corporate Procurement Policy, which inform our evaluations for the Supplier Relationship Management scorecards and are part of our supplier selection criteria. In 2022, we started outreach to suppliers who had previously opted out of the EcoVadis system that rates businesses on their Environment, Labor Practices & Human Rights, Fair Business Practices, and Sustainable Procurement practices.

In 2021, Trinseo contracted Beroe, Inc. to analyze records related to financial checks, anti-corruption, sanctions and due diligence records, EcoVadis business sustainability ratings, and health and safety alerts to evaluate suppliers’ compliance with our sustainability requirements. It revealed that 9% of our suppliers have a current EcoVadis badge. According to Beroe, 10% is considered best in class. From this evaluation, we have started implementing an EcoVadis participation program for vendors.
