Celanese Achieves ISCC Carbon Footprint Certification for POM ECO-C Grades, Expanding Circular Economy Leadership

Key Terms

carbon footprint certification technical

A carbon footprint certification is a formal, usually third-party, assessment that measures and verifies the total greenhouse gas emissions associated with a company, product, or activity. For investors it works like an energy bill or health check: it reveals exposure to regulation, potential costs or savings from efficiency, and reputational risks or advantages, helping compare companies on climate-related financial risk and long-term resilience.

international sustainability & carbon certification technical

A credential issued by recognized global programs that verifies a company’s environmental practices and the measurement, reduction, or offsetting of its greenhouse gas emissions. For investors, it acts like a trusted report card and passport: it reduces uncertainty about regulatory and reputational risk, can affect operating costs and market access, and helps gauge whether a business is progressing toward lower-carbon operations that many customers and funds now prefer.

carbon capture and utilization technical

A set of technologies and processes that capture carbon dioxide from industrial emissions or the air and convert it into useful products (like fuels, chemicals, or building materials) or store it safely so it won’t re-enter the atmosphere. Investors care because it can turn a pollution problem into a new revenue stream, reduce regulatory or carbon-cost risk, attract government subsidies or credits, and affect a company’s future costs, competitiveness and long-term value.

life cycle assessment technical

A life cycle assessment is a systematic review of the environmental impacts of a product or service across its entire existence — from raw material extraction through manufacturing, use, and disposal. For investors, it acts like a full 'environmental health check' that reveals hidden costs, regulatory and supply-chain risks, and opportunities for efficiency or branding that can affect long-term profitability and valuation.

greenhouse gas technical

Gases such as carbon dioxide, methane and nitrous oxide that trap heat in the atmosphere like a blanket, causing global temperatures to rise. For investors they matter because regulation, carbon pricing, physical damage from extreme weather and changing consumer preferences can alter a company’s costs, profits and long‑term value, so measuring and managing these emissions affects financial risk and opportunity.

Celanese POM ECO-C – setting a new sustainability benchmark in POM

DALLAS--(BUSINESS WIRE)-- Celanese Corporation (NYSE: CE), a global leader in specialty materials and chemicals, has achieved Carbon Footprint Certification (CFC) from International Sustainability & Carbon Certification (ISCC) for its Hostaform® and Celcon® POM ECO-C grades at production sites in Frankfurt, Germany, and Bishop, Texas - expanding its network of certified facilities to empower customers to reduce product carbon footprints and accelerate the transition to a circular economy. This milestone underscores Celanese’s commitment to sustainability and innovation.

Advancing Lower-Carbon Solutions

This certification is the result of Celanese’s major investment in Carbon Capture and Utilization (CCU) technology at its Clear Lake, Texas facility as a part of its Fairway Methanol joint venture with Mitsui & Co., Ltd. - one of the world’s largest active CCU plants. The process captures CO₂ emissions and converts them into methanol, reducing fossil-based inputs without compromising material performance.

Key Highlights:

• Certified Sustainability: ISCC CFC certification provides third-party verification of carbon footprint reduction.

• Performance Retained: POM ECO-C maintains hallmark properties - high stiffness, thermal stability, sliding performance, and wear resistance - now with the lowest carbon footprint POM to date.

• Global Reach: Certification at Frankfurt and Bishop strengthens Celanese leadership in sustainable engineering plastics.

Digital Transparency with Chemille® - Digital Assistant
