Environmental Product Declarations

An EPD is an environmental declaration providing quantified environmental data using predetermined parameters and, where relevant, additional environmental information. (ISO 14025: 2006). Put more simply, an EPD describes the environmental impact of a specific product similar to a food nutrition label.

See the FHWA Tech Brief: Environmental Product Declarations for more information. 

The Oregon Legislature passed House Bill 4139 (2022). Its intention is to reduce greenhouse gas (GHG) emissions from materials and fuels used by the Department of Transportation. The legislation requires ODOT to collect EPDs. This information helps inform agency decisions that reduce GHG emissions without sacrificing performance. ODOT will apply EPD information to understand current construction practices better. We continue to understand our use of local and regional resources and technologies. In understanding, we'll work to improve highway construction projects across Oregon's different regions and districts.

The resources listed below are links to external sites from ODOT. ODOT is providing these resources as informational. There may be a more current version of the PCR available. If you're using these resources, it's your responsibility to verify you're using the most current PCR version for EPD development.
