What is the Greenroads performance metric? A performance metric for roadway design and construction that awards points for more sustainable practices. Greenroads helps quantify the sustainable attributes of a roadway project. Who is developing Greenroads? Greenroads is being developed jointly by the University of Washington (UW) and CH2M HILL. Importantly, although UW and CH2M HILL are developing this system, the brand associated with any pilot project or rated project will only be the Greenroads brand.

What can Greenroads do? Define what project attributes contribute to roadway sustainability. Provide a sustainability accounting tool for roadway projects. Communicate sustainable project attributes to stakeholders. Manage and improve roadway sustainability. Stimulate the market for sustainable practices and products Save money Overall goal: improve roadway sustainability Sasobit Warm Mix Asphalt I-90 near George, WA 23 June 2008
Greenroads is a project-oriented system It does not deal with planning and it does not deal with operations. Quiet Pavement SR 520 Near Bellevue, WA 14 July 2007 Planning Design & Construction Operation
Sustainability is the next great game in transportation. The game becomes serious when you keep score. Greenroads keeps score.
