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.

In 2017, KUB’s fleet earned Tennessee Green Fleet certification from the Tennessee Clean Fuels Coalition. In addition to meeting annual regulatory requirements of the Energy Policy Act of 1992, KUB's commitment to alternative fuels is estimated to have prevented the combustion of nearly 85,000 gallons of gas and diesel over the past three years. That's equivalent to roughly 550 short tons of greenhouse gas emissions.

KUB has a long-standing relationship with the Tennessee Clean Fuels Coalition as Gold partner since 2004. Through this partnership, we learn 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 charging stations at certain facilities.
