Start Certification

CST seeks to not only improve the environment, but also to help owners, operators and manufacturers reduce costs, strengthen energy and environmental performance, and demonstrate to the public a commitment to sustainability.

Owners & Operators


The Certification for Sustainable Transportation's (CST) eRating vehicle certification and driver training programs can help you reduce costs, save energy, and promote your transportation company.

The "e" in "eRating" represents what the program is: an easy, economical way to promote environmentally friendly, energy efficient transportation options and education programs.

We evaluate vehicles with research-based criteria. Our straightforward application is easy to complete and each vehicle(s) application undergoes rigorous review.

Owners and operators with certified vehicles benefit through:
