GreenLITES certification categories are Sustainable Sites, Water Quality, Materials and Resources, Energy and Atmosphere, and Innovation.

Like Greenroads, GreenLITES certifies projects at increasing levels of sustainability: Certified, Silver, Gold and Evergreen. More information is available at www.dot.ny.gov/programs/greenlites.

• GreenPave. In 2010 the Ontario Ministry of Transportation launched GreenPave, a points-based rating system which focuses on pavements, not the entire right-of-way. MTO’s goal is to establish a rating system for pavement sustainability that applies to all designs of asphalt and concrete pavement structures.

• I-LAST. The Illinois Livable and Sustainable Transportation (I-LAST) Rating System and Guide was rolled out in January 2010 and is a sustainability performance metric system developed by the Joint Sustainability Group of the Illinois DOT, the American Council of Engineering Companies-Illinois, and the Illinois Road and Transportation Builders Association, among other statewide groups.

The use of I-LAST is voluntary. I-LAST includes a point system for evaluating the sustainable measures included in a project. Download the I-LAST manual at www.dot.state.il.us/green/documents/I-LASTGuidebook.pdf
