EcoVadis Rating for Vinnolit and Westlake Practiced Corporate Social Responsibility

Responsibility for people and the environment is a core value at Westlake. Emphasis on this topic is all the more important as corporate social responsibility (CSR) expectations for global supply chains are on the rise. As evidence of our commitment, Vinnolit has been regularly reviewed by the independent global assessment platform EcoVadis (www.ecovadis.com) for a number of years.  Again, it evaluated Vinnolit’s Corporate Social Responsibility (CSR) performance and again Vinnolit achieved an excellent rating (“Gold Recognition Level”).

Also, Westlake began the process of having its US chemical sites evaluated by EcoVadis as well.  After its first evaluation, Westlake's U.S. chemicals operations received a bronze rating, placing above average and in the 50th percentile of evaluated companies.  EcoVadis describes companies with a bronze rating as having a "structured and proactive CSR approach with engagements/policies and tangible actions on major issues."
