Carbon Leadership Forum

Embodied Carbon in Construction Calculator (EC3)

EC3 calculates and compares the carbon footprint of alternative building material products

Purpose

To help building professionals make better decisions about embodied carbon in construction, and encourage supply chain accountability, by providing a free and open-source database of construction materials and their environmental impacts.

About

In collaboration with C-Change Labs, the Carbon Leadership Forum is developing the EC3 tool to help construction professionals efficiently quantify, report and reduce embodied carbon. EC3 will enable a performance-based approach to embodied carbon reductions in design, procurement, and construction. A public open source EPD database and building planner will launch by November 2019. Currently, the tool is in a pilot phase based at the Microsoft Campus. Overall, the tool will enable simple (but not simplistic) assessments of embodied carbon.
