Environmental product declarations (EPDs) and product life-cycle assessments (LCAs) are essential for manufacturers of building materials to quantify, report, and reduce the environmental impacts of their products. Selecting the appropriate EPD software ensures compliance with sustainability construction standards, such as the Construction Products Regulation (CPR) and the Ecodesign for Sustainable Products Regulation (ESPR), and streamlines data collection, modeling, and reporting. Below is a comparison of the leading EPD and product LCA software solutions for 2025, highlighting their product category specializations, supported standards, and regional scopes.
