EC3 2.0 Beta and Open Embodied Carbon Data at Greenbuild 2026

Building Transparency is showcasing EC3 2.0 at Greenbuild 2026, a full rebuild of its open-access embodied carbon calculator for construction materials. The platform now holds more than 250,000 Environmental Product Declarations across 200 plus material categories, with tools for comparing products and tracking project-level carbon. The beta launch focuses on the Find and Compare Materials module, with more features rolling out in phases. The nonprofit is also introducing a membership program to fund the infrastructure while keeping core tools free. Separately, its Open Data for Climate Initiative is developing verified generic life cycle assessment datasets for regions that lack product-specific EPDs, starting with cement, concrete, timber, and steel. That work is meant to support Buy Clean programs and embodied carbon policies that depend on reliable, comparable data.

Good to see EC3 moving to 2.0. The open EPD data angle matters more than the beta. 250k EPDs sounds big, but the real test is whether smaller manufacturers actually keep them updated. Curious how the new membership fees stay optional without splitting the user base.

The ODCi piece is the one to watch. Generic LCA datasets for regions without product-specific data are what Buy Clean programs outside North America will need. If the verification framework holds, this makes embodied carbon policy easier to enforce. Membership is a fair way to keep it public.

EC3 has always been useful for comparing concrete and steel, but the new Find and Compare workflow will tell if it is actually faster on a real project. The data quality indicators matter more than the UI. If EPDs are stale, the tool just gives confident answers from bad inputs.

Not really grid related, but embodied carbon matters for all the concrete and steel in transmission and storage projects. If ODCi covers 58 material categories across seven regions, does that include the stuff used in substations and foundations? Or is it only building materials?

Building Transparency has been quietly carrying the open EPD infrastructure for years. The Amazon and Google funding helps, but membership gives a steadier base. Just hope the premium features do not end up hiding the data that smaller firms rely on.

The Greenbuild beta launch is a solid milestone. EC3 2.0 being a full rebuild should cut down the clunky parts of the old tool. Will test it when the Project Planner module opens up. That is where the actual project-level carbon tracking happens.
