The business case for NanoEFX — ROI and ESG
The business case starts with measured fuel consumption. A verified reduction can lower fuel spend and, using the same fuel data and emission factor, reduce calculated Scope 1 CO₂. Use the calculator to model a fleet-specific planning scenario — not a guaranteed return.
What drives the business case — and how to model it
The return
- Most documented trials between 5% and 15% less fuel, median 10.7% — and a small, inconclusive result on one duty cycle
- Financial impact scales with annual fuel use, fuel price and the consumption reduction you actually measure.
- No retrofit capex: NanoEFX is an operating treatment, not a hardware retrofit.
- Lower fuel use can reduce exposure to ETS2-related carbon-cost pass-through in road-transport fuel prices — see the regulatory context for the current timetable.
How to size it
- Use the calculator to model potential fuel-cost savings and an ETS2-related carbon-cost scenario using your own fleet, fuel-price and reduction assumptions.
- The calculator shows an indicative gross benefit. Net ROI and payback also depend on the actual NanoEFX programme cost and the fuel-consumption reduction measured in your fleet.
- 5-year projection and a copyable report
- Indicative only — not a guarantee
From measured fuel use to operating costs and Scope 1 CO₂
A measured fuel reduction can lower operating costs and, using the same fuel data and applicable emission factor, reduce calculated Scope 1 CO₂. Evidence for local pollutants is separate and is reported with its own measurement conditions and limitations.
For the CFO — lower fuel cost
Fuel consumption is a direct operating-cost driver. NanoEFX is applied as an operating treatment rather than a hardware retrofit, so there is no retrofit capex and no hardware installation downtime. The financial result depends on the fuel-consumption reduction measured in your fleet and the actual programme cost.
- Direct reduction in fuel spend
- Lower fuel use can reduce exposure to ETS2-related carbon-cost pass-through in road-transport fuel prices — see the regulatory context for the current timetable.
- No retrofit capex: NanoEFX is an operating treatment, not a hardware retrofit.
For ESG — calculated Scope 1 CO₂ and accredited local-pollutant evidence
Reduced fuel burn means lower CO₂, calculated from your own measured consumption. On local pollutants, our one accredited measurement — by JATA in Japan — recorded 30.4% less CO, 23.3% less HC and 15.1% less NOx on a treated vehicle.
- NOx down 15.1%, CO down 30.4% on one vehicle — accredited measurement
- CO₂ for Scope 1 reporting, calculated from measured fuel use
- Durability not measured — the accredited reading covered 88 km between the two measurements
How a fuel reduction becomes a Scope 1 number
For vehicles and equipment within your Scope 1 organisational boundary, fuel combustion is a direct emission under the GHG Protocol. For the calculation used on this site, CO₂ is calculated from fuel consumed and the applicable emission factor. Using the same factor and method, a measured reduction in fuel use produces a proportional reduction in the calculated CO₂ figure.
Two consequences are worth stating plainly. The number depends on your fuel data, not on ours. What makes it defensible in a report is your own metered consumption over a defined period against a defined baseline — which is exactly what a pilot is designed to produce, and what our measurement methodology sets out.
And every CO₂ figure on this site is arrived at this way — calculated from the fuel figure, not measured at the exhaust. Our one accredited exhaust measurement covers local pollutants and found CO₂ essentially unchanged at the tailpipe. The CO₂ saving comes from burning less fuel, not from changing what is in it.
A UNIDO STePP listing — and an SDG badge for treated vehicles and equipment
NanoEFX is listed on STePP, the Sustainable Technology Promotion Platform operated by UNIDO (United Nations Industrial Development Organization). The listing associates the technology with Sustainable Development Goals 7, 9, 11 and 13; it is not a performance test. Separately, users of NanoEFX or ecoSPRAY are authorised to display the SDG badge on treated fossil-fuel-powered vehicles, vessels, generators, machinery and other combustion-engine equipment.
