Over the past few years, the City of Shreveport has added a number of CNG-fueled vehicles to its commercial fleet. Several city buses and garbage packer trucks are now fueled by Compressed Natural Gas rather than diesel. And more CNG vehicles are being added.

So when it came time to pick a keynote speaker for the 2014 Louisiana Alternative Fuels Conference and Expo, organizers picked Mayor Cedric Glover.

The mayor's office says SporTran is one of the few public transit systems nationwide with multiple vehicles powered by Compressed Natural Gas.

Glover tweeted that SporTran saves around $350,000 each year, and creates less ozone and C02.

Shreveport was also in the spotlight that afternoon at the Louisiana Clean Fuels Awards Ceremony when Lt. Governor Jay Dardenne presented the award for municipalities to SporTran Director Gene Eddy.
