Advancing Sustainability: IRI Maturity Model Insights from Eastman, GAF, and PPG

Advancing Sustainability highlights how leading companies are embedding sustainability into innovation using the IRI Sustainability Maturity Model, which defines four stages, Beginning, Improving, Succeeding, and Leading. The model offers a roadmap for integrating sustainability into strategy, culture, and product development.

Case studies of Eastman, GAF, and PPG illustrate this progression. Eastman’s A Better Circle initiative advances circularity through large-scale molecular recycling, GAF’s Reflector Series combines energy efficiency with design, and PPG’s SIGMAGLIDE 2390 delivers biocide-free marine coatings that reduce emissions.

The paper shows that sustainability and innovation are inseparable, advancing along the maturity model enhances environmental impact, competitiveness, and long-term growth. Collaboration, clear metrics, and organizational alignment are key to achieving lasting progress.
