Environmental Product Declarations (EPDs) Provide Environmental Transparency - EPDs Help Support Sustainable Building Design - EPDs Can Help Projects Earn LEED Credits - EPDs Measure Important Environmental Metrics Green building certification programs and sustainable design practices have become mainstream. Today’s architects and their clients demand not only greater transparency but also easily accessible resources to help them design more sustainable buildings and meet sustainable design benchmarks such as those outlined by the LEED® rating systems. **As a result, Environmental Product Declarations (EPDs) have become valuable assets to architects and designers.** In 2017, Vitro was the first North American manufacturer to publish third-party verified [Environmental Product Declarations (EPDs)](https://www.vitroglazings.com/design-resources/sustainability/) for flat glass and processed glass products. In 2024, the General Services Administration (GSA) announced new standards for products that can be considered Low Embodied Carbon (LEC). As part of achieving these standards, products must offer a Type III EPD with a Global Warming Potential (GWP) in kilograms of carbon equivalent per metric ton (kgCO2 eq/ton) of glass. Vitro recently announced it received an updated EPD for its flat glass products that indicates its architectural glass products contain just 1,240 kilograms of CO2 equivalent, which is 13% lower than the National Glass Association’s industry standard. Based on these results, all Vitro Architectural Glass products meet the Top 20% ("Most Preferred") LEC material category. This lowest embodied carbon designation applies to all Vitro-produced architectural glass from all Vitro plants all the time. Now, with the help of EPDs, design professionals have access to documentation that makes it easier than ever to confirm the sustainability of North American processed glass products—and thus, earn LEED® credits for projects. ### **What Are EPDs?** EPDs are voluntary and transparent reports made by companies regarding the life-cycle impacts of their products on the environment. Reporting and documentation for product-specific EPDs address energy use and emissions associated with a product’s manufacture and packaging, as well as the extraction, transportation and processing of related raw materials. ### Why You Need Them EPDs can help projects earn LEED® credits. For more information on utilizing Vitro Glass products to earn LEED® credits, visit the [Vitro Glass Guide to LEED®](http://www.vitroglazings.com/en-US/Resources/Sustainability/LEED-Overview.aspx). Vitro Glass also provides a pathway to LEED credit through the *Cradle to Cradle Certified*® (C2C) Products Program under the same category. In 2008, Vitro Architectural Glass (known then as PPG Glass) became the first U.S. glass company to have its entire range of products *Cradle to Cradle Certified*® and, today, continues to offer one of the largest collections of architectural glass brands qualified to this rigorous, globally recognized lifecycle standard. ### Which Products Are Covered? The product-specific flat glass EPD is valid for all annealed and untreated glass products manufactured by Vitro Glass. The product-specific processed glass EPD is valid for Vitro Glass products that undergo secondary treatment, such as the addition of magnetron sputtered vapor deposition (MSVD) coatings, heat-strengthening or fabrication into multi-pane insulating glass units (IGUs). In addition, both EPDs published by Vitro Glass are certified by ASTM International as conforming to the requirements of ISO 14025. Life cycle assessments (LCAs) for flat glass and processed glass products were performed according to ISO 14040, ISO 14044 and EN 15804 following the product category rules (PCRs) for each product type.
