Trinseo’s Tatianna Yam Yee Yung, Senior Project & Program Manager, Sustainability, was named a Plastics News’ 2025 Notable Leaders in Sustainability. This award recognizes plastics industry leaders who oversee sustainability initiatives and are making a measurable impact through their efforts.
Yung leads efforts to advance Trinseo’s Scope 3 greenhouse gas emissions strategy, which included implementing supply chain and procurement training programs, establishing the Scope 3 Council, and building supplier relationships. She directed the Company’s first comprehensive Scope 3 Inventory calculations, which received limited assurance from ERM CVS, an independent third-party verification company. This milestone laid the foundation for Trinseo to manage and track Scope 3 emissions, which resulted in the Company achieving one of its Climate Change goals a year early.
“I’m honored to be recognized as a leader in the industry. This acknowledgment reinforces my commitment to continue pushing boundaries and exploring innovative ways to make a meaningful impact in Scope 3 management and tracking,” said Yung.
Inclusion in Plastics News’ Notable Leaders in Sustainability list underscores Yung’s influence in the industry and her commitment to advancing a sustainable supply chain. She is the third leader at Trinseo to be honored with this recognition.
