Interpretation
Based on the results of the life cycle assessment model, the environmental impacts are primarily driven by the A1- A3 product stag which accounts for 71% of the cradle-to-grave Global Warming Potential (GWP)– fossil. Additional significant contributors include installation (A5), and product distribution (A4), contributing approximately 11%, and 12% of total GWP impacts, respectively. End-of-life activities (C1–C4) contribute 7% of impacts.
Installation remains a notable contributor to overall environmental impacts due to the assumptions required by the applicable Product Category Rules (PCRs). In the absence of site-specific installation data, the PCR requires the application of a 10% installation waste scenario. Because installation practices vary significantly among contractors and project conditions, CertainTeed has limited influence over these impacts. Furthermore, the use of internally recycled gypsum and other recycled materials helps reduce the demand for virgin raw materials, thereby lowering upstream environmental burdens associated with raw material extraction and processing.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
