Which Software Tracks Construction Equipment Carbon Emissions?

Key Takeaways

• The data source decides how useful an emissions number is.
• Fuel invoices give you a total. Machine activity data shows where the total came from.
• Idling is usually the most recoverable part of an equipment fleet’s footprint.
• In the UAE, measuring emissions is now a legal obligation for in-scope entities, not only a tender requirement.

The number most sites cannot explain

Picture a monthly sustainability review. The fuel report shows 40,000 litres of diesel, the carbon figure follows from it, and someone asks the obvious question: how much of that was burned by machines waiting for a truck, a permit, or an operator? On most sites, nobody can answer. The total is accurate. It is simply not useful for deciding what to change.

That is the real difference between the tools below.

Three types of software, three different answers

Equipment and fleet management platforms connect to each machine and convert engine-on time into a CO2 figure. The data is per asset and per day, so it works across mixed fleets and multiple sites.

OEM telematics portals report fuel burn and emissions for one manufacturer’s machines. They are reliable for that brand, but most construction fleets run several brands plus rented and subcontractor equipment.

ESG carbon accounting tools estimate emissions from fuel purchases and published emission factors. They suit company-level disclosure, but they cannot tell a site manager which excavator idled for half a shift.

How the CO2 figure is calculated

Fuel burned in equipment a company owns or controls counts as a direct emission. Under the GHG Protocol, emissions from sources owned or controlled by the reporting company are Scope 1, and that includes fuel burned in mobile combustion sources. ducky

The conversion itself is simple. The US EPA’s emission factor for diesel is 10.21 kg of CO2 per gallon, which works out to roughly 2.7 kg per litre. So every 100 litres burned at idle is about 270 kg of CO2 with no work to show for it. epa

The hard part is not the maths. It is knowing how many of those litres were productive.

Why this matters more in the UAE now

Federal Decree-Law No. 11 of 2024 entered into force on 30 May 2025 and requires in-scope entities to measure, report and reduce greenhouse gas emissions. Guidance on the law points to identifying all relevant emission sources and keeping auditable records for five years. For a contractor, equipment is one of the largest of those sources, and a fleet-wide estimate is harder to defend than a machine-level record. pwc

How TENDERD tracks equipment emissions

TENDERD’s Emissions module turns each machine’s engine-on time into a carbon figure and presents it in three views:

• Dashboard: total, working, and idling CO2 for the fleet over a chosen period, with a daily trend and a breakdown by machine type.
• Machines: a per-machine view, sortable by idling emissions, with a day-by-day chart.
• Modelling: a forecast of cumulative CO2 based on target utilization rate, expected number of machines, ramp-up period, and project duration.

At Aramco SPARK (King Salman Energy Park), a pilot covering 50 pieces of equipment recorded a 38% reduction in idling emissions in four months.

Conclusion

The right software depends on the question you need answered. For a company-wide disclosure, an accounting tool may be enough. To reduce construction equipment carbon emissions on site, you need machine-level data that shows where idling happens. See how TENDERD’s Emissions module works.
