About Sun Tran

Protecting the Environment

The service we provide at Sun Tran is essential to improving air quality in our community by taking cars off our busy streets and utilizing clean-burning fuels. Do your part, ride Sun Tran!

How is Sun Tran helping our environment?

Cleaner-Burning Fuels

Now 100 percent of Sun Tran's fleet uses cleaner-burning fuels, including hybrid technology, Compressed Natural Gas (CNG) and Biodiesel. These fuels reduce emissions because they emit fewer particulates than traditional diesel-fueled vehicles. For more information on Sun Tran's fleet, visit Fleet Facts.

Environmental Management System (EMS)

Sun Tran's maintenance facility is the first United States transit maintenance facility to earn EMS certification compliant with the ISO 14001 standard. What does ISO 14001 mean? It's the system standard established by the International Organization for Standardization. Certification of the EMS to this standard demonstrates that an organization has a strong management system in place for continually improving its environmental performance with regards to regulatory compliance and pollution prevention.

Sun Tran is strongly committed to maintaining a safe and clean environment, preventing pollution and preserving the community's natural desert resources.

Visit Sun Tran's EMS Policy for more information, or contact Steve Boberg, Sun Tran's Environmental Management System Manager at (520) 206-8835.

Solar Powered Lights at Bus Shelters

Sun Tran takes advantage of living in sunny Tucson by utilizing solar energy to provide lighting at many bus shelters throughout our community. These shelters reduce the amount of energy we use to provide safe and well lit shelters for our passengers.
