The Greenroads Rating System

The recipe book for your sustainable transportation project.

The GreenroadsĀ® 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 evaluates projects through independent, expert, third-party review.

The Rating System and all Greenroads Programs are administered by the 501c3 nonprofit organization, Greenroads International.

Join a free webinar for an introduction to the Rating System. See what a Greenroad looks like by visiting our Project Portfolio.
