The Infrastructure Voluntary Evaluation Sustainability Tool (INVEST) is a web-based self-evaluation tool to assess and enhance the environmental, social and economic sustainability of transportation projects. The tool aims to support a sustainable construction and maintenance of highways and other transportation projects to satisfy societal development and economic growth while enhancing the natural environment and reducing natural resource use. The tool offers four different modules throughout the life cycle: System Planning for States (SPS), System Planning for Regions (SPR), Project Development (PD) and Operations and Maintenance (OM). Each module is independent, measures sustainability across individual criteria and is evaluated separately.
Depending on the performance concerning the individual criteria, projects are scored. The scoring provides recognition for implementing sustainability best practices and helps identify gaps and opportunities. The process can lead to improvements in practice and identification of cost-effective measures.
Sustainability criteria depend on the module used.
