“Sustainability is embedded in how we operate and underpins our purpose of creating materials that improve daily life and enable a more sustainable future,” said Sean Keohane, president and CEO. “I am immensely proud of the unwavering commitment of our teams across the globe as we close out our 2025 Sustainability Goals while making headway on our next key priorities, delivering meaningful impact today and for future generations. As we advance in our efforts, we remain focused on strengthening the integration between our sustainability agenda and our Creating for Tomorrow strategy, ensuring sustainability remains a catalyst for value creation and differentiation.”

Key Highlights from the 2026 Sustainability Report

By the end of 2025, Cabot achieved 14 of its 15 2025 Sustainability Goals, with 11 met ahead of schedule. Established in 2020, the 2025 Sustainability Goals accomplished Cabot’s objective of strengthening its systems, evolving its practices, and further integrating sustainability into how it operates its business.

With the introduction of its 2030 Sustainability Goals, which outline six priority topics identified as most impactful to the company, Cabot has already made meaningful progress toward its targets as well as other focus areas that support additional material sustainability topics. Notable milestones include:

• Advancing Product Carbon Footprints (PCF): Completed a collaborative initiative with the International Carbon Black Association (ICBA) to develop an industry-wide life cycle assessment (LCA) methodology for furnace carbon black. Building on this effort and in support of its 2030 Sustainability Goal, Cabot plans to develop a proprietary, externally certified tool to track PCF across its entire product portfolio, enhancing transparency, accuracy and credibility.
  
• Increasing Beneficial Reuse of Material: Established an innovative beneficial reuse pathway that converts synthetic gypsum generated by the air pollution control system at its Franklin, Louisiana, USA facility into a valuable input for cement manufacturing. This initiative reduced nonhazardous landfill waste at the site by 87% and contributed to a 70% reduction in nonhazardous waste sent to landfill globally from 2024 to 2025.
  

“As we conclude our 2025 Sustainability Goals, we are entering the next chapter of our sustainability journey with momentum and clear direction,” said Jennifer Chittick, senior vice president, safety, health and environment (SH&E) and government affairs, and chief sustainability officer. “Building on our strong foundation of safety, innovation and operational excellence, we are making measurable progress toward our targeted 2030 Sustainability Goals through initiatives that reduce our environmental footprint and strengthen our overall impact across our value chain. Through collaboration, process optimization and strategic investments in technology, I am confident that we will continue to advance our commitments and deliver long-term results for our stakeholders worldwide.”
