Custom EC3 API simplifies finding lower embodied carbon products

The first product data provider to partner with Building Transparency & the EC3 tool in 2019. We collaborated to create a custom API to provide simple, in-a-glance comparative results; and later, Buy Clean CA eligibility data to find EPDs for Buy Clean in 1 click.

A 50-page methodology document in a tool tip. The methodology is an innovation in comparing embodied carbon impacts. The tooltip provides a description of the process and key to the visual results with interpretation guidance.

Every EPD links back to the Transparency Catalog to connect the last mile. Every MFR’s page and their EPDs link to their Transparency Catalog Listing to find the products, transparency documentation and contact information for you to select, specify and procure lower embodied carbon materials.

The first program operator to partner with Building Transparency & the EC3 tool. We ensure the EPDs we create get added to the EC3 tool quickly and accurately.
