For most contractors, the sound of engines running is reassuring - a sign that work is progressing, crews are active, and productivity is up.

But every day, a portion of those machines are running for nothing. A truck keeps its engine on while waiting to load. An excavator sits still because the next crew isn’t ready. A piece of equipment remains parked because it hasn’t yet been reassigned.

Taken individually, these moments seem trivial. But when added up, they represent a major waste: wasted fuel, unnecessary CO₂ emissions, and accelerated machine wear. The real issue? Most of the time, we simply don’t measure how big the problem is.

Let’s look at how idle time impacts both your operations and the environment - and how you can take concrete steps to reduce it.

Key takeaways
  • Idling wastes fuel, wears out machines, and increases your carbon footprint.
  • Every engine hour without production = money lost and avoidable emissions.
  • Lack of measurement hides the real scale of the issue.
  • Hiboo measures idling precisely, while Civalgo helps eliminate it through better planning.

The hidden environmental cost of idling

Every liter of fuel burned while idling releases CO₂ - without producing value or moving the project forward.

Take a simple example: an excavator burns between 3 and 5 liters of fuel per idle hour.

  • If it idles for two hours a day, that’s 6 to 10 liters wasted daily.
  • Multiply that across your fleet and over several weeks, and you’re talking hundreds of liters - gone for nothing.

Behind these numbers lie two realities:

  • Economic: You’re paying for fuel that generates no value.
  • Environmental: Those wasted liters translate into tons of avoidable CO₂ emissions each year.

As the construction sector faces growing scrutiny over its environmental impact, reducing idle time isn’t just a smart financial move - it’s a sustainability action that strengthens your bids, certifications, and reputation.

Step 1: Measure before you act

The first barrier is the lack of visibility. It’s not that contractors don’t care - it’s that they often don’t know how much time their machines spend idling, because no one tracks it precisely.

That’s where a tool like Hiboo changes everything. Hiboo collects and translates real-time telematics data from your machines - usage, idle time, location, fuel consumption, mechanical alerts - making it easy to analyze and act on.

With this data, you can:

  • Identify underperforming machines: On average, 30% of engine time is idle. Cutting that by just 10 points saves up to 600 L of fuel per machine per year - roughly €1,900 in savings and 1.9 tons of CO₂ avoided.
  • Compare similar machines to spot efficiency gaps, optimizing allocation and extending lifespan - leading to a 200–400% ROI on maintenance, as seen with our clients.
  • Calculate the exact financial and carbon impact of idling: across a 1,000-machine fleet, that’s up to €840,000 saved annually and 1,900 tons of CO₂ avoided.

In short: once you make the invisible visible, you can act - and achieve measurable financial and environmental gains.

Step 2: Plan smarter - for performance and sustainability

Reducing idle time isn’t just about telling operators to shut off engines more often. It’s mainly about organization and scheduling.

Behind every idle machine, there’s usually a coordination issue:

  • a resource that arrived too early,
  • a crew not ready,
  • equipment sitting idle because no one has decided where to send it next.

With Civalgo, you connect Hiboo’s usage data directly to your project schedules. The result:

  • You assign the right equipment to the right jobs.
  • You reduce unnecessary moves and delays.
  • You anticipate critical phases to limit downtime.
  • You plan fuel needs more accurately.

Fewer engines running for nothing, less CO₂ released, and smoother operations across the board.

Best practices to cut idle time - and your carbon footprint

Here are a few easy, actionable tips:

1. Track idle rates continuously

With Hiboo, you can see how much each machine idles. That’s your starting point for targeted action.

2. Reassign instead of renting

A machine underused on one site can be moved to another. By linking Hiboo and Civalgo, you spot idle equipment and redeploy it - instead of renting more.

3. Raise operator awareness

Show crews how much one idle hour costs in fuel and CO₂. Awareness often drives change faster than directives.

4. Plan critical phases precisely

Fewer downtime windows mean fewer running engines. With Civalgo, you align your schedules with on-site reality.

5. Integrate preventive maintenance

Poorly maintained machines consume more fuel and idle longer. Hiboo alerts you to anomalies, and Civalgo helps plan maintenance without disrupting schedules.

Conclusion

Reducing idle time isn’t just about saving fuel - it’s about running a smarter, more sustainable business. You cut emissions, extend equipment life, and enhance your company’s image.

And the good news is, Hiboo x Civalgo makes it simple:

  • With Hiboo, you measure the impact of idling precisely.
  • With Civalgo, you turn that insight into concrete planning decisions.

Together, these two complementary tools help contractors simplify operations and align performance with sustainability - less fuel burned, smoother workflows, stronger margins, and a lighter carbon footprint.

That’s where profitability and sustainability finally meet.

Civalgo and Hiboo are developing an integration that will help contractors track idling time, cut fuel waste, and reduce CO₂ emissions, without sacrificing performance. Schedule a Civalgo demo to discover how the platform already helps optimize operations and discuss this next step with our team.
