Environmental Product Declarations (EPD)

The purpose of the Caltrans Environmental Product Declaration (EPD) Implementation Project is to collect EPDs for materials incorporated into construction projects in order to quantify the Global Warming Potential (GWP) emissions in the manufacturing of those materials for our transportation system.

Five major building materials put into service by Caltrans have been identified to include Concrete, Carbon Steel Rebar, Structural Steel (SS), Asphalt, and Aggregate and will be the initial set of materials to which EPDs will be collected and used for determining baseline GWP emissions.

The Buy Clean California Act, originally signed into law on October 15, 2017 and amended on June 27, 2018, mandates collection of EPDs for eligible materials (carbon steel rebar, structural steel, flat glass, and mineral wool board insulation) to which this project will include in its deliverables.

Product Category Rules

Use the product category rule in effect on the date of bid opening unless otherwise authorized. Where a product category rule for material or product has expired without replacement as of the bid opening date, no environmental product declaration is required for that particular material or product.

Where separate bid item exists (Pilot Projects only): Submit a schedule of values for material and product environmental product declarations within 15 days after Contract approval.
