Clearing the Air in St. Louis
St. Louis Clean Cities is cutting emissions on the banks of the Mississippi.

APUs allow truckers to power appliances and climate-control systems without idling the engine.
Boats, trains, and automobiles in the St. Louis region are running a lot cleaner these days, thanks in part to the tireless work of Kevin Herdler, executive director of St. Louis Clean Cities (SLCC).
With Herdler at the helm, the organization fosters deployment of a broad range of alternative fuels and fuel-saving technologies. In 2011 alone, SLCC’s efforts averted more than 76,000 tons of transportation-related emissions and saved 8.5 million gallons of petroleum.
“As a military veteran, I see the impacts of our dependence on foreign oil,” Herdler said. “I like the idea of using American fuel and supporting American jobs. And, on top of that, there’s the benefit of cleaner air.”
Located at the intersection of several railroads, four interstate highways, and the mighty Mississippi, SLCC is well positioned to take on high-impact transportation projects on road, rail, and river.
Herdler has worked with eight school districts in the St. Louis area to install fuel-fired heaters in more than 700 school buses. The heaters use a very small quantity of fuel to warm up bus engines and heat their interiors, eliminating the need for drivers to idle before they set off on routes.
“The heaters have been a blessing for these school districts — they’re yielding huge savings,” Herdler said.
Herdler has also worked with hundreds of long-haul truckers to cut idling through the installation of auxiliary power units (APUs) that heat cabs and power appliances, allowing truckers to turn engines off and maintain cabin comfort.
With funding assistance from the State of Missouri, SLCC is helping an agricultural company upgrade a 1953 railroad locomotive with a modern, efficient engine that will use B-20 and is expected to cut overall fuel use by 50-80 percent
In another state-funded project, Herdler is helping a barge cleaning and repair company replace old diesel engines on five of its boats. As of March, three of the boats had been fitted with more fuel-efficient engines and saved 85,000 gallons of diesel fuel in their first six months of operation.
“I try to expand our work out into all sectors,” Herdler said. “And, our stakeholders are working hard together to make St. Louis a real green city.”

Bobit Business Media surveyed 190 fleet professionals and found that while most fleets are tracking costs, fragmented systems and data gaps are keeping true TCO visibility out of reach. With rising pressure to control spend in an increasingly volatile environment, the gap between what fleets think they know and what the data actually shows is wider than you might expect. See how your peers are managing costs today and where the industry still has room to improve.
