NSF and GANA Develop Flat Glass Product Category Rule

NSF International, an independent global organization that writes standards, and tests and certifies products, in collaboration with the Glass Association of North America’s Flat Glass Manufacturing Division, has developed a product category rule for flat and float glass.

Flat glass, for purposes of the PCR, includes sheet glass, plate glass, rolled glass and float glass, for use in architectural, automotive and decorative applications. The PCR (UN CPC 3711) provides both a science-based and internationally recognized method for reporting the environmental impact of glass products and materials throughout their life cycle from cradle to gate, according to an NSF release.

Product category rules define how to conduct a life cycle assessment for a product group and what data to include in the resulting environmental product declaration, the third-party-verified report that explains the data generated from an LCA. The U.S. Green Building Council’s Leadership in Energy and Environmental Design v4 recognizes the value of PCRs/EPDs and includes credit language that recognizes EPDs.

“Developing the flat glass PCR with NSF International is an important next step toward a more sustainable future for the glass industry,” said Urmilla Jokhu-Sowell, GANA Technical Director, in the release. “This PCR will give glass manufacturers an opportunity to identify and focus on reducing the environmental impacts of their products and operations and to differentiate themselves in the marketplace.”

The flat glass PCR was established in accordance with international environmental management guidelines (ISO 14025: Environmental labels and declarations -- Type III environmental declarations) through the NSF National Center for Sustainability Standards. NSF International’s NCSS utilized an open consultative process to develop the PCR with participation from an expert panel of glass manufacturers, suppliers, regulatory agencies, life cycle practitioners, trade associations and end users. The NCSS has developed PCRs and American National Standards in sustainability for a wide range of product categories, including chemicals, commercial furnishings, flooring, building products and materials, and water treatment and distribution systems.

“The development of product category rules for flat and float glass helps meet the increasing demand for transparency in environmental claims. Our robust PCR development and EPD validation services are focused on assisting industries in meeting these market demands with science-based and verifiable information,” said Tom Bruursema, General Manager of NSF International’s Sustainability Division, in the release.
