CST meaning in Governmental ?

The Certification for Sustainable Transportation is a national program housed at the University of Vermont Extension that seeks to promote the practice of using energy efficient modes of transportation. The CST work centers on its eRating vehicle certification program, which is an eco-label for passenger transportation vehicles. The eRating uses a sustainability index which includes factors such as green house gas emissions per passenger mile, emission levels of criteria pollutants, and in certain circumstances factors such as training for drivers and use of endorsed carbon offsets. Once a certain threshold is met, vehicles may qualify for e1, e2, e3, or e4 levels in the certification program.

Other key components of the CST's work are online and in person training programs. The CST offers training programs geared to help drivers and organizations eliminate all unnecessary idling and on eco-driving. These training programs are focused on helping reduce environmental impacts, save fuel, and save money.

The CST is now actively working with companies in 48 states and three Canadian provinces to prevent unnecessary emissions, reduce environmental impact, and decrease consumption of fossil fuels.

This program is not to be confused with the "E-Mark" vehicle equipment safety certification promulgated by the European Union since 2002 under EU Directive 72/245/EEC and amendments to the requirements of Directive 95/54/EC.
