Embodied Carbon in Construction Calculator (EC3)

The Embodied Carbon in Construction Calculator (EC3) is a free, cloud-based platform that enables benchmarking, assessment, and reduction of embodied carbon in construction materials. Developed through collaboration between nearly 50 industry partners, EC3 utilizes building material quantities from construction estimates and BIM models combined with a robust database of over 24,000 digitized, third-party verified Environmental Product Declarations (EPDs). The tool allows architects, engineers, contractors, and policymakers to compare materials during design and procurement phases to identify low-carbon alternatives.
