We’re on a mission to scale climate action in the built environment by bringing actionable carbon data to every design and real estate professional on the planet. No more spreadsheets or incomplete calculations. Our model helps teams determine which measures are most impactful and which are not, ensuring that scarce resources can support the best strategies. We’re working towards a future where every project team working on every building has the tools to reduce emissions and contribute to a healthy and equitable built environment.

C.Scale is a team of architects, data scientists, and software engineers focused on solving real problems on real projects. Before C.Scale was a stand-alone company, we led sustainability and climate strategy at EHDD, an award-winning sustainability-focused firm in San Francisco.

The data models behind C.Scale began with Jack Rusk at the Yale School of the Environment, where he was wrestling with how to streamline life cycle assessment for building sector practitioners. EHDD partner Brad Jacobson, FAIA, saw the usefulness of these models in evolving net zero energy to net zero whole life carbon design. Through this collaboration, C.Scale was born.

An early version of C.Scale was instrumental in EHDD winning and delivering the net zero whole life carbon AIA Headquarters renovation. Now, C.Scale aims to make these data and approaches available to practitioners everywhere.
