Construction projects can typically achieve a 10-20% reduction in embodied energy and carbon without increasing build costs, according to circularecology. A 10-20% reduction in embodied energy and carbon presents a direct, cost-neutral path for the industry to cut its environmental impact.
Sophisticated digital tools now streamline embodied carbon measurement and tracking. Yet, current procurement systems often hinder acting on this crucial data. Advanced capabilities clash with outdated operational frameworks.
Robust data and integrated tools are increasingly available. The construction industry must fundamentally rethink material selection and procurement. Environmental impact will soon stand alongside traditional cost metrics.
What is Embodied Carbon, and How Do We Measure It?
Embodied carbon refers to greenhouse gas emissions tied to a material's full lifecycle: extraction, manufacturing, transport, construction, and disposal. Precise calculation is crucial for reduction. For example, one ton of steel carries approximately 1.7 tons of embodied carbon dioxide, as noted by wicci.
Specialized tools simplify this complex calculation. The Embodied Carbon in Construction Calculator (EC3) tool processes material quantities from estimates or BIM models. It cross-references this data with a vast database of Environmental Product Declarations (EPDs), according to the Carbon Leadership Forum. EPDs offer transparent, third-party verified environmental performance data for materials.
One Click LCA provides the largest global Life Cycle Assessment (LCA) database, with over 250,000 verified datasets. Together, these platforms convert abstract material choices into quantifiable environmental impacts. The conversion of abstract material choices into quantifiable environmental impacts makes embodied carbon concrete and actionable for project teams.
