A resource for policymakers, agency staff, project teams, researchers, tool developers, and others, this report provides:
- a “state of EPDs” snapshot of North American construction materials,
- a set of industry-average CLF baseline embodied carbon values (or “baselines”) for construction products, and
- ein supporting methodology.
To drive action built on informed comparisons, the baselines serve as a basis of comparison for evaluating individual products in low-carbon procurement policies, green building rating systems, and project specifications. They also serve as average embodied carbon intensity values for project-scale modeling.
Key updates in this version include:
- updated data and baseline values that reflect the current state of EPDs in 2025;
- new categories like asphalt mixtures, applied fireproofing, brick, ceramic tile, and more;
- more baseline values, reflecting new EPD data and CLF’s expansion of baseline-setting methods.
Dive in…there’s a lot in there. And we look forward to hearing from you. |
