To avoid an irreversible and catastrophic climate change trajectory, we must limit average global temperatures to well below a 2°C increase from pre-industrial levels. Mitigating average global temperature increase is strongly linked to reducing carbon footprints; thus, relevant accounting metrics such as embodied carbon and life cycle footprinting are becoming an increasingly urgent issue. There are currently many ratings, certifications, corporate pledges, and new regulations driving the building industry to provide sustainability transparency & embodied carbon information. These include regulations that will require the use of Environmental Product Declarations (EPDs) (e.g., the Federal BuyClean Regulation and the California Assembly Bill 2446). In addition, the Inflation Reduction Act (IRA) has tasked the US Environmental Protection Agency (EPA) with aiding industry to standardize and digitize EPDs. Because EPDs summarize results of Life Cycle Assessment (LCA) studies, expanding access to quality LCA data and standardizing LCA approaches within specific product categories are essential to producing quality EPDs. This project focuses on lighting products as a case study: it has been identified that there is a “data gap” in EPDs in lighting and mechanical, electrical & plumbing (MEP) products that could affect many EPD inputs in a whole building LCA.
