Analyser les impacts environnementaux de la chaîne d'approvisionnement CLT de Katerra, ainsi que de son Catalyst Building.

À propos

Katerra a mandaté le Carbon Leadership Forum (CLF) et Centre pour le commerce international des produits forestiers (CINTRAFOR) at the University of Washington to analyze the environmental impacts of its CLT as well as the Catalyst Building in Spokane, Washington. The Catalyst is a 15,690 m2 (168,800 ft2), five-story office building that makes extensive use of CLT as a structural and design element. Jointly developed by Avista and McKinstry, Katerra largely designed and constructed the building, and used CLT produced by Katerra’s new factory.

Performing a life cycle assessment (LCA) on Katerra’s CLT will allow Katerra to explore opportunities for environmental impact reduction along their supply chain and improve their CLT production efficiency. Performing an LCA on the Catalyst Building will enable Katerra to better understand life cycle environmental impacts of mass timber buildings and identify opportunities to optimize the environmental performance of mid-rise CLT structures.  CINTRAFOR performed the LCA on Katerra’s CLT, and the CLF performed the LCA on the Catalyst Building.

Reclaimed and Reused: Recommended LCA Modeling Guidance to Support EPDs for Reused Construction Materials

Material reuse is one strategy for reducing the embodied carbon of construction. While the preparation of previously used materials for reuse has an environmental impact, it avoids many of the resource extraction and manufacturing impacts of building with newly manufactured products. Given the amount of demolition and deconstruction across North America (and beyond), there is a vast potential for material reuse to expand in scale. However, barriers to material reuse scaling exist.

DEQ Low Embodied Carbon Housing Program: Roadmap to Success

Embodied Carbon Pathways to 2050 for the United States, a collaboration between the Carbon Leadership Forum (CLF), RMI, and the University of Washington (UW) Life Cycle Lab, provides an assessment of embodied carbon from US construction materials and explores pathways to align with a 1.5°C global warming limit.

International Embodied Carbon Data Availability: A Review of Environmental Product Declaration (EPD) Availability in Europe, China, and Australia

CLF completed a landscape analysis of product-level embodied carbon data availability in regions outside North America with the goals of: (i) understanding how LCA/EPD data availability varies globally; (ii) informing where targeted initiatives are needed to increase the availability of data; and (iii) determining whether adequate EPD data exists to develop CLF Material Baselines outside North America. This report summarizes our findings and provides initial insights into what data is available to inform low-carbon procurement efforts in Australia, China, and Europe.

The CLF Benchmark Explorer

Emissions from the operations of buildings and infrastructure are significant, well-understood contributors to national and global greenhouse gas emissions. However, the contribution of embodied carbon—emissions associated with the manufacturing, transportation, installation, maintenance, and disposal of construction materials across the life cycle of a building or asset—is neglected by comparison. Even at the global level, embodied carbon estimates are typically based on manufacturing emissions from the production of a handful of the highest-impact materials (e.g. concrete, steel, aluminum, and wood).
