You Can’t Control Fuel Prices. You Can Control Fuel Waste.

Fuel costs remain one of the largest operating expenses for passenger transport operators. Across Europe and the UK, fuel now accounts for between 25% and 35% of total fleet operating costs, and recent price spikes have only intensified the pressure on margins.

The challenge is obvious: operators cannot control what happens at the pump.

What they can control is how efficiently that fuel is used.

The Hidden Cost Most Fleets Overlook

When fuel costs rise, many organizations focus on procurement strategies, route optimization, or vehicle replacement programs. Yet one of the largest drivers of fuel consumption sits behind the wheel.

Studies consistently show that driver behavior accounts for 15–25% of fuel consumption variance across fleets. Harsh acceleration, excessive idling, reactive braking, and poor anticipation of traffic conditions all contribute directly to unnecessary fuel spend.

Even when two drivers operate the same vehicle on the same route, fuel consumption can vary significantly based on driving style alone.

Small Behaviors. Big Financial Impact.

The difference between an efficient driver and an inefficient driver is not subtle.

Efficient drivers accelerate smoothly, maintain steady speeds, and anticipate traffic conditions. Less efficient drivers create unnecessary fuel burn through aggressive acceleration, late braking, and constant throttle corrections.

According to GreenRoad pilot data, the portion of energy consumption directly influenced by drivers can represent as much as one-third to one-half of a vehicle’s total energy usage.

For a fleet operating 100 buses running hundreds of kilometers every day, even small improvements in driving efficiency can quickly translate into six-figure annual savings.

Visibility Drives Improvement

Fuel waste is often difficult to identify until the costs have already been incurred.

The most successful operators make fuel efficiency part of daily management. They provide drivers with real-time feedback, identify inefficient driving patterns early, and use performance data to focus coaching efforts where they will have the greatest impact.

The result is not only lower fuel consumption, but also safer driving, reduced vehicle wear, and improved operational performance.

The Bottom Line

Fuel prices will always be outside your control.

Fuel waste is not.

With fuel representing up to a third of fleet operating costs, improving driver behavior remains one of the fastest and most measurable ways to reduce expenses without reducing service levels. The fleets that treat fuel efficiency as a behavior challenge—not just a procurement challenge—will be best positioned to protect margins in an increasingly volatile market.

Safe journeys don’t happen by accident. Neither do fuel savings.
