The CLF North American Material Baselines Report provides a snapshot of the state of Environmental Product Declarations (EPDs) for North American-produced building materials. This report includes:<\/span><\/p>\n

    \n
  1. Background and methodology<\/span><\/li>\n
  2. CLF Baselines<\/span><\/li>\n
  3. Appendices<\/span><\/li>\n<\/ol>\n

    We’ve recently published the 2025 CLF North American Material Baselines. For the latest version, please visit the report webpage<\/a><\/strong>, published in June 2025.<\/p>\n

    About<\/h2>\n

    The CLF Baseline values represent an estimate of industry-average GHG emissions for construction materials manufactured in North America. An overwhelming majority of the CLF Baselines published in this report are based on a North American industry-wide EPD if one was available at the time of publication. As such, it is appropriate to use this number as a rough estimate of a product type\u2019s embodied carbon before a specific product has been selected or as a reference value against which product-level comparisons can be made.<\/p>\n

    Each material category has a detailed appendix that includes a description of the embodied carbon impacts, the available EPDs, and summary statistics. The Appendices in this report allow users to better understand the availability of existing industry-wide and product EPDs, and the variability of product types across a category. The snapshot of available EPDs summarized in each Appendix was assembled using the EC3 database in Fall 2022.<\/p>\n

    Version 2 Updates<\/h2>\n

    Version 2 (August 2023) of the report fixes typos, adds the remaining 8 appendices, and improves accessibility of the report and appendices by adding bookmarks and hyperlinks to the PDF files. There were no changes made to the Baseline Table of Values content. <\/p>\n
