2017 Embodied Carbon Benchmark Study V1

Pregunta de investigación

¿Cuáles son las magnitudes y rangos típicos del carbono incorporado en los edificios?

Sobre

los Estudio de referencia de carbono incorporado es la primera etapa del LCA para construcción baja en carbono proyecto financiado por The Fundación Charles Pankow, Skanska USA y Departamento de Calidad Ambiental de Oregón. La evaluación del ciclo de vida (LCA) es el método utilizado para cuantificar las emisiones de carbono que se producen al extraer materiales y fabricar productos de construcción, también conocido como "carbono incorporado". Aunque existe un reconocimiento creciente de la necesidad de rastrear y reducir las emisiones de carbono incorporadas, los profesionales de la industria de la construcción necesitan mejores datos y orientación sobre cómo implementar métodos bajos en carbono en la práctica. 

Este proyecto compiló la base de datos más grande conocida de carbono incorporado en la construcción y creó una base de datos interactiva. Esta etapa del proyecto estableció un consenso sobre el orden de magnitud del carbono incorporado en un edificio típico, identificó fuentes de incertidumbre y describió estrategias para superar esta incertidumbre. El informe resume los hallazgos clave de esta investigación, incluido el punto de referencia, y proporciona la base para la etapa dos de este proyecto, el desarrollo de un Guía práctica de ACV.​

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.

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).
