The U.S. Department of Transportation Federal Highway Administration (FHWA) views sustainable highways as an integral part of sustainable development, which is why it developed INVEST (Infrastructure Voluntary Evaluation Sustainability Tool) — a practical, Web-based collection of best practices that allow states to integrate sustainability into their transportation projects. The use of the tool is voluntary and can be used by states or other project sponsors to measure the sustainability of their projects.

What is the Purpose and Intent of this Tool?

FHWA’s INVEST identifies characteristics of sustainable highways and provides information and techniques to help agencies and organizations integrate sustainability best practices into highway and other roadway projects. The tool is intended to provide a method for practitioners to evaluate their transportation projects and to encourage progress in the sustainability arena.

It is not required and it is not intended to encourage comparisons across transportation agencies and projects. The tool is being developed with ongoing input from state and local transportation agency officials and staff, and professional organizations such as the American Association of State Highway and Transportation Officials (AASHTO) and the American Society of Civil Engineers (ASCE). FHWA plans to continue to update this tool as the transportation sustainability field advances.
