Guide des solutions concrètes RMI

Le guide RMI Concrete Solutions publié en août 2021 fournit un aperçu convivial des solutions éprouvées et évolutives pour réduire la contribution du béton au changement climatique. Le guide met en évidence six opportunités clés pour réduire le carbone incorporé dans les produits en béton sans compromettre les performances financières ou matérielles :

  1. Connaissez vos chiffres : Spécifications axées sur la performance
  2. Mélangez-le : Matériaux cimentaires supplémentaires (SCM)
  3. Plug and Play : les capteurs peuvent économiser du temps, de l'argent et du matériel
  4. Adoptez la circularité : le recyclage du béton
  5. Carbon as a Service : séquestrer le CO2 dans le béton
  6. Utiliser la chaleur verte : décarboniser la technologie du four

Selon RMI, « la plupart des solutions décrites sont prêtes pour le marché, le résultat de décennies de recherche et d'essais en conditions réelles. En plus d'aider à faire progresser les objectifs environnementaux des acheteurs de béton, ces solutions offrent aux producteurs des opportunités de réduire les coûts et d'établir un rôle de leader dans une industrie en évolution.

Le Guide des solutions concrètes RMI vise à fournir des solutions utiles à travers le réseau complexe d'acteurs de la chaîne de valeur du ciment et du béton, des producteurs de béton et des fabricants de ciment aux développeurs, concepteurs, entrepreneurs et décideurs.

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).
