FHWA Climate Challenge - Quantifying Emissions of Sustainable Pavements

FHWA’s Climate Challenge identified more than 35 projects from 27 agencies (including 2 local agencies), providing $7.1 million to 25 state departments of transportation. FHWA Technical assistance will be provided to all the 27 agencies.

Over the next two years participants will receive training and work with various stakeholders including industry and academia to implement projects that quantify the environmental impacts of pavements using life cycle assessment (LCA) and environmental product declarations (EPDs).
