About<\/h2>\n

In 2017, the CLF published the <\/span>Embodied Carbon Benchmark Study<\/span><\/a> for North American buildings. Since then, the practice of whole-building life cycle assessment (WBLCA) has grown rapidly in the AEC industry, and it has become clear that more robust and reliable benchmarks are critical for advancing work in this field. The new CLF WBLCA Benchmark Study (Version 2) is built upon research and insights from the 2017 study. The project expanded our research methodology, included more comprehensive data collection, and resulted in a high-resolution dataset of harmonized WBLCA model results and project design characteristics for nearly 300 buildings across the United States and Canada. <\/span>With this data, the team analyzed the impacts of buildings, identified drivers of high and low-carbon projects, and published benchmarks for multiple applications. Outcomes from this project enable designers and decision-makers to set reliable embodied carbon targets and understand the potential for reduction throughout the design and construction processes.<\/span><\/p>\n

This project fills a critical gap in the AEC industry and helps to enable architects, engineers, policymakers, and the entire design community to work towards realistic and measurable embodied carbon reductions at the building scale.<\/p>\n<\/blockquote>\n<\/blockquote>\n

\u00a0Project Components<\/h2>\n

There are 3 components to this project that build on each other to ultimately deliver a more robust dataset, analysis framework, and set of benchmarks:<\/p>\n

    \n
  1. Pilot Phase (2022 – 2023):<\/strong> The pilot phase set forth the development and testing of data collection processes and data analysis methods to support future work throughout the study. This phase involved conducting background research, hosting industry workshops, establishing pilot partners, and collecting pilot dataset of projects to inform the feasibility and infrastructure for future work.<\/li>\n
  2. California Carbon Report (2023 – 2024):<\/strong> This project component focused on the whole-life carbon impacts of a discrete set of buildings in California and examined the relationship between embodied and operational carbon impacts over time when considering future grid decarbonization projections. It culminated in the California Carbon Report: An Analysis of the Embodied and Operational Carbon Impacts of 30 Buildings, which can be downloaded on the California Carbon Report<\/a> webpage.<\/li>\n
  3. North American Benchmarks and Database (2024-2025):<\/strong> Throughout 2024, the CLF collected a dataset of 200+ high-quality WBLCA models of real-world building projects with the help of over 30 firms located in North America. In the spring of 2025, the dataset was published open-access for all to use. The research team used the dataset to conduct statistical analysis on the embodied carbon impacts of buildings and provide estimates of typical, low, and high values for buildings in North America. A full list of publications from this phase, including reports, dashboards, and journal papers, can be found below<\/span>.<\/li>\n<\/ol>\n

              We are thrilled to announce the release of an open-access dataset of WLBCA results from the project. The dataset encompasses highly detailed and harmonized building design characteristics, material quantities, and environmental impacts for 292 building projects across the United States and Canada. In total, the dataset represents nearly 5 million square meters of newly constructed floor area.<\/p>\n

              The dataset aims to enable designers, owners, researchers, and policymakers to analyze and compare the impacts of buildings, set performance targets, and motivate impact reductions. We hope this catalyzes future initiatives within the field to expand the scope and scale of LCA data collection and achieve higher levels of detail and methodological harmonization to support research on sustainable design and construction practices.<\/p>\n

              You can access the dataset here<\/a> and read about how it was created and how to use it here<\/a>. Enjoy!<\/p>\n
