The Greenroads® Rating System is an easy way to measure and manage sustainability on transportation projects. The Rating System is the core publication used in the Greenroads Project Rating Program, which challenges Project Teams to go above and beyond minimum environmental, social, and economic performance measures and evaluated by an independent, expert, third-party review. The Rating System and all Greenroads Programs are administered by the 501c3 nonprofit organization, Greenroads International.
