From Data Your Vehicles Already Send
California clean-fleet rules keep evolving. The fuel and emissions data your vehicles already send gives you a running start on the paperwork.
Clean Truck Check
For California fleets, Geotab's Emissions Diagnostics Report is CARB Clean Truck Check certified (December 2024), generated straight from the CARB-compliant GO9 tracker kit.
Geotab holds both CARB Clean Truck Check certification and the anti-tampering Executive Order exemption (Geotab). Enrollment, deadlines, and records live in the platform already tracking the vehicles, so compliance becomes a status you check, and we help confirm eligibility.
Compliance
The same devices tracking your fleet collect what compliance reporting needs.
Engine and usage data captured without driver effort.
Organized records when submission windows open.
Alerts and schedules keep filings from sneaking up.
A team sets up your compliance workflow with you, not a ticket number.

The Numbers Both Sides Ask For
The Sustainability Overview tracks the figures that show up in compliance files, grant applications, and customer sustainability questionnaires.
CO2e per mile, the normalized figure that lets a growing fleet still show progress.
Metric tons CO2e for the fleet, computed with published EPA conversion factors (8.81184 kg CO2e per gallon of gasoline) for US fleets.
Tailpipe emissions avoided by any EVs already in the fleet, documented for the same reports.
The entire dashboard exports to Excel, and new data populates monthly.

Clean Truck Check status and the Sustainability Overview sit beside the tracking, maintenance, and safety data.
A closer look
California reporting runs on vehicle data you already collect. These are the screens and records that turn it into a filing.
One dashboard rolling up emissions figures, exportable for filings.
The certified report for Clean Truck Check filings, generated from the truck's own data.
Where every enrolled vehicle stands, at a glance.
History and figures organized and time-stamped for the day a regulator asks.
Per-vehicle fuel use and miles, the raw inputs behind every figure.
Models which vehicles can move to EV and plans charging.
Questions
The tracker captures the engine and mileage data these programs rely on and can reduce manual paperwork. Always confirm current requirements against the regulation itself.
Yes. The Emissions Diagnostics Report is CARB Clean Truck Check certified (December 2024) and runs off the CARB-compliant GO9 tracker kit. GPSFMS helps you confirm eligibility and set it up for your vehicles.
Electrification tools help you assess which vehicles can transition and plan charging with data.
The Sustainability Overview rolls the fleet up to three figures, with the methodology and Excel export covered in the dashboard section above.
Yes. Customer sustainability questionnaires, grant applications, and state programs outside California increasingly ask for the same fuel, idling, and emissions figures. The reporting layer is the same; only the mandate differs.
