      About<\/h2>\n

      The 2025 CLF North American Material Baselines project continues the work of and builds upon previous CLF Material Baselines reports. This report aims to support decision-makers by providing:<\/p>\n

      A methodology<\/strong> for:<\/p>\n

        \n
      • categorizing products for appropriate embodied carbon comparisons;<\/li>\n
      • collecting and processing embodied carbon data from EPDs; and<\/li>\n
      • assessing data sources for their industry representativeness and estimating industry-average embodied carbon values (i.e., \u201cbaselines\u201d) per product type.<\/li>\n<\/ul>\n

        Category results<\/strong>, including:<\/p>\n

          \n
        • a \u201cstate of EPDs\u201d snapshot of North American construction product EPD GWP data; and<\/li>\n
        • a set of CLF baseline GWP values or \u201cCLF Baselines\u201d that represent an estimate of industry-average GHG emissions for construction materials manufactured in North America. Their primary uses are:\n
            \n
          • a basis of comparison; a reference point against which individual products can be evaluated; and<\/li>\n
          • default GWP intensity values for project- or assembly-scale modeling.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
