Eastman Named 100 Best Corporate Citizens 2025 for Sustainability Leadership
Eastman has been named one of the 100 Best Corporate Citizens of 2025 by 3BL, a leading sustainability communications organization. This esteemed recognition highlights Eastman’s strong dedication to sustainability, transparency, and performance among the largest publicly traded companies in the U.S. The company earned the 36th spot overall and ranked eighth within the materials sector.
“Being a responsible corporate citizen has been central to Eastman’s mission for more than a century,” said Mark Costa, Eastman’s board chair and CEO. “This honor reflects our steadfast commitment to tackling the world’s most urgent challenges through sustainable materials and solutions. Our strategy is rooted in guiding principles that shape our purpose, leadership, actions toward carbon neutrality, and commitment to circularity. We are proud to receive continued recognition from 3BL on this distinguished list.”
The 100 Best Corporate Citizens ranking assesses Russell 1,000 companies using 219 factors across seven key areas: climate change, employee relations, environmental stewardship, governance, human rights, and stakeholder and societal engagement. In 2024, the methodology was updated with dozens of new factors to better measure corporate performance and disclosure, and in 2025, adjustments were made to increase the emphasis on certain performance-based metrics, as well as enhancements from ISS Sustainability Solutions to the E&S Disclosure QualityScore and Governance QualityScore.
“Responsible business has faced significant challenges this year, yet the companies on this list have demonstrated the resolve to maintain their commitments,” said Charlie Wilkie, CEO of 3BL.
“In today’s environment, where trust is a key performance indicator, these companies show that transparency and accountability form the foundation of stronger organizations. The 100 Best Corporate Citizens ranking highlights these strengths and continues to elevate standards for corporate leadership each year.”
Unlike other evaluations, the 100 Best Corporate Citizens ranking is based entirely on publicly available information, without requiring questionnaires, company submissions, or fees. Companies can verify the data used for the ranking at no cost. The 2025 rankings were based on information published between June 2024 and June 2025.
