2017 Embodied Carbon Benchmark Study V1

Domanda di ricerca

Quali sono le magnitudini e gli intervalli tipici del carbonio incorporato negli edifici?

Di

Il Studio di benchmark sul carbonio incorporato è la prima fase di LCA per costruzioni a basse emissioni di carbonio progetto finanziato da L Fondazione Charles Pankow, Skanska USA e Dipartimento per la qualità ambientale dell'Oregon. La valutazione del ciclo di vita (LCA) è il metodo utilizzato per quantificare le emissioni di carbonio che si verificano durante l'estrazione di materiali e la realizzazione di prodotti da costruzione, altrimenti noti come "carbonio incorporato". Sebbene vi sia un crescente riconoscimento della necessità di tracciare e ridurre le emissioni di carbonio incorporate, i professionisti del settore edile necessitano di dati e indicazioni migliori su come implementare nella pratica metodi a basse emissioni di carbonio. 

Questo progetto ha compilato il più grande database conosciuto di carbonio incarnato da costruzione e ha creato un file database interattivo. Questa fase del progetto ha stabilito un consenso sull'ordine di grandezza del carbonio tipico degli edifici, ha identificato le fonti di incertezza e ha delineato le strategie per superare questa incertezza. Il rapporto riassume i risultati chiave di questa ricerca, compreso il benchmark, e fornisce le basi per la fase due di questo progetto, lo sviluppo di un Guida pratica LCA.​

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).
