We’re fostering a better building future by addressing embodied carbon’s role in climate change.

Building Transparency's core 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.

Our premier service is the Embodied Carbon in Construction Calculator (EC3), a free database of construction EPDs and matching building impact calculator for use in design and material procurement.
