Fleet Decarbonization Audit

A $499 audit that baselines your fleet's fuel spend, cost per mile and CO₂ emissions from your own data, then designs a measured hydrogen-assist pilot so any savings are proven on your vehicles before you scale.

Price: $499 one-time, per audit
Scope: Diesel and petrol fleets: vans, rigid trucks and HGVs
You receive: Fuel and emissions baseline plus a pilot design with pass/fail criteria
Best for: Fleets not yet ready to switch to battery-electric

Who it is for

Operators of diesel or petrol vans, rigid trucks and heavy goods vehicles.
UK companies reporting energy use and emissions under SECR.
Fleets where range, payload or charging access rules out battery-electric vehicles for now.
Finance teams that want fuel savings proven before approving hardware spend.

What we review

Fuel: 12 months of fuel card data or invoices.
Distance: mileage records or telematics exports.
Vehicles: list by class, engine, age and duty cycle.
Operations: routes, idling, maintenance cost and tyre management.
Reporting: how emissions are measured and reported today.

What you receive

A baseline per vehicle class: fuel economy, cost per mile or kilometre, and annual CO₂ using published government conversion factors (UK DESNZ or US EPA).
A comparison against typical figures for each vehicle class.
A hydrogen-assist pilot design: which vehicles, a control group, duration, measurement method and pass/fail criteria.
A projected payback range, clearly labelled as an estimate until the pilot results are in.
Quick wins that need no hardware, such as idling, route and tyre-pressure changes.

What we need from you

Fuel card exports or fuel invoices for the last 12 months.
Mileage or telematics data for the same period.
A vehicle list with class, fuel type and year.

Questions about this assessment

Will the audit guarantee a fuel saving?

No. Results from hydrogen-assist vary by engine and duty cycle. That is why the audit designs a controlled pilot, measured against your own baseline, rather than promising a fixed percentage.

Which vehicles can be included?

Diesel and petrol vehicles from light vans to heavy goods vehicles. Mixed fleets are assessed class by class.

Does this help with UK SECR reporting?

Yes. The fuel and emissions baseline uses the same kind of data SECR reporting needs, so it gives you a verified starting point.

Can I estimate the savings before booking?

Yes. The free ICE Fleet Savings calculator gives an estimate from a few inputs. The audit replaces those assumptions with your real data.
