2023 CLF North American Material Baselines Report

Carbon, Environmental Product Declaration (EPD), Non-Global Warming Potential (GWP) Benefits

Developed by the Carbon Leadership Forum (CLF), this report provides an overview of the state of building product EPDs in North America. The CLF baselines are industry-wide GWP estimates for all building products manufactured in North America, most of which are based off of IW-EPDs, if available. The appendix includes a list of all the domestic EPDs available for each product category, and a summary of embodied carbon impacts.
