KUB's well-known white trucks first went “green” in the 1970s. That's when KUB converted some vehicles to run on compressed natural gas (CNG). Today, KUB is proud to have a fleet powered by CNG, electric and hybrid technology, and E85 flex fuel. These vehicles represent KUB’s commitment to reducing emissions for improved air quality and saving on fuel consumption.

KUB’s fleet has maintained Tennessee Green Fleet certification from the Tennessee Clean Fuels Coalition (TCFC), in addition to meeting annual regulatory requirements of the Energy Policy Act of 1992. KUB serves on the Board of the TCFC and has been a Gold Partner since 2004. Through this partnership, KUB learns about the latest technologies and grant opportunities while we help support the alternative fuels industry.

KUB also participates in the Tennessee Workplace Charging Partnership. KUB provides electric vehicle information to its employees, evaluates the level of interest in workplace charging, and provides access to electric vehicle charging stations at certain facilities.
