In order for a community to thrive, a complex network of interconnected systems must be there to support it. This is true for things in both the natural and technological world. Building Transparency’s EC3 tool is an example of a technology built to support and inform a thriving ecosystem, in this case embodied carbon accountability in the built environment. Hear about the thinking behind its creation as an open-access, free tool as well as examples of how it is being used to connect systems and people in our journey to zero embodied carbon emissions.


Building Transparency is a new non profit established to continue the management and scaling of the Embodied Carbon in Construction Calculator (EC3) tool. Building Transparency’s mission is to provide the open access data and tools necessary to enable broad and swift action across the building industry in addressing embodied carbon’s role in climate change.
