Embodied Carbon: A Clearer View of Carbon Emissions

International engineering firm
Walter P Moore has released a groundbreaking stewardship report entitled Embodied Carbon, A Clearer View of Carbon Emissions.

The report focuses on an issue of relevance for all material specifiers, which is the reduction of greenhouse gas emissions. The report first defines embodied carbon, then Walter P Moore experts address why and how members of the AEC industry must work in concert to reduce embodied carbon.

“Reducing embodied carbon is essential to achieving near-term reductions in greenhouse gas emissions. This report discusses both what can be done today and strategies to eventually achieve net zero embodied carbon,” said Dirk Kestner, Principal and Director of Sustainable Design for Walter P Moore. “I encourage AEC professionals to engage in the report, explore resources and tools, and continue to dialogue in regard to embodied carbon.”

Embodied Carbon, A Clearer View of Carbon Emissions includes milestones related to embodied carbon, a series of technical writings that define why embodied carbons matter, case studies on decarbonization in practice, and a final perspective that defines a path to net zero.

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).
