Carbon Leadership Forum

Increasingly the building industry and owners are becoming aware that materials matter and are seeking ways to evaluate the emissions associated with making these materials, but they have not had a reliable or efficient way to compare them. The open-source Embodied Carbon in Construction Calculator (EC3) tool simplifies this complex problem giving users the information they need to make more informed decisions on embodied carbon, allowing them to enact positive change. Details on the EC3 tool will be made available November 2019. Collaborating partners will be demonstrating the product at Greenbuild, November 19-22, 2019 at the Georgia World Congress Center, Atlanta, GA.

The EC3 story

As owners, designers, engineers and contractors are turning their attention to embodied carbon associated with building materials and seeking information on these products so they can make informed, smart choices. This task has been fraught with problems – from the lack of data to data too complex to evaluate.

In response to this problem, Skanska USA and C Change Labs conceived of a solution that would enable the building industry to easily access and view material carbon emissions data, allowing them to make carbon smart choices during material specifications and procurement. Initial development was jointly funded by Skanska and Microsoft, who determined that an open platform would provide maximum impact for the industry and society at large. To accelerate development of this solution, the Carbon Leadership Forum incubated the project with strong leadership and additional financial support from Autodesk, Interface, the MKA Foundation and the Charles Pankow Foundation, lead sponsor and grant manager. Subsequently, more than 30 other industry-leaders joined in.

EC3 community

The EC3 tool is being incubated by the Carbon Leadership Forum in collaboration with core development partner C Change Labs and the generous support, both financial and in-kind by over thirty industry organizations and hundreds of individuals. This initiative is an excellent example of what can happen when the Carbon Leadership Forum’s passionate and collaborative network comes together around a shared need for collective impact.
