Press Release | June 8, 2023

WILMINGTON, Del., June 8, 2023 —DuPont™ Styrofoam™ Brand ST-100 Extruded Polystyrene Foam (XPS) has received the 2023 ACC Sustainability Leadership Award in the Environmental Protection category.

The ACC recognizes significant company achievements and contributions to sustainability, with this award focusing on organizations that have implemented innovative and successful sustainability initiatives, demonstrating significant accomplishments in environmental protection. Winning entries were reviewed internally by the ACC and judged by an independent panel, comprised of external sustainability experts.

“Our Styrofoam™ Brand ST-100 XPS Insulation delivers a significant 94% reduction in embodied carbon, a huge step towards decarbonization in the building and construction industry.” said Dr. Anson Wong, Lead Scientist, DuPont Performance Solutions. “We are grateful to be recognized for this work by the ACC, which is a testament to the strong dedication, creativity, and teamwork of our cross-functional team that made our StyrofoamTM Brand ST-100 XPS Insulation a reality. I am truly blessed to be a part of the team that delivered this product, and I am motivated to continue working with them to develop new innovations to help build a sustainable future for the place that we call home.”

Building upon an 80-year history of Styrofoam™ Brand XPS products, Styrofoam™ Brand ST-100XPS Insulation was developed as a low-Global Warming Potential (GWP) solution to meet market needs for low-embodied carbon products and to drive climate action. DuPont’s Styrofoam™ Brand ST-100 XPS Insulation innovation delivers a substantial 94% reduction in embodied carbon across the product life cycle, while still providing the same operational carbon savings through stable, long-term insulation value for new and retrofitted buildings, supporting DuPont’s commitment to reduce greenhouse gas (GHG) emissions while driving sustainable innovation.

For over a decade, XPS insulation products have relied on hydrofluorocarbon (HFC) blowing agents to achieve important foam properties such as density and thermal insulation, but many HFCs are potent GHGs based on their relatively high intrinsic Global Warming Potentials (GWPs). DuPont innovators seized the climate action challenge to reinvent Styrofoam™ Brand Insulation by developing an innovative low embodied carbon solution that has achieved a significant reduction in GHG emissions across the product life cycle. The new optimized HFO-based, low-GWP blowing agent formulation achieves a wide range of product properties such as mechanical strength, R-value, and moisture and fire resistance. StyrofoamTM Brand ST-100 XPS Insulation has also achieved the maximum points possible under the Embodied Carbon/LCA Optimization credit within the LEED Green Building certification scheme because of the significant magnitude of the embodied carbon reduction.

This latest award-winning innovation together with Froth-Pak Spray Foam, which was recognized in 2021 with the ACC Sustainability Leadership Award in the Environmental Protection category, supports the DuPont Performance Building Solutions and Corian® Design business’ Acting on Climate’ goal to achieve a 75 percent reduction in Scope 1 and 2 GHG emission from operations by 2030, as well as DuPont’s updated Acting on Climate goal that has been recently validated by the Science-Based Targets initiative.
