Fleet Vehicle Emissions Monitoring and Log Checklist [FREE PDF]

Fleet vehicle emissions represent a significant Scope 1 source under the GHG Protocol Corporate Standard and must be systematically monitored, logged, and reported in accordance with EPA 40 CFR Part 98 Subpart C for organizations meeting mandatory reporting thresholds. Accurate fleet emissions data is also essential for CDP Climate disclosure, Science Based Targets transport sector pathways, and EU ETS compliance for companies operating in regulated jurisdictions. This checklist enables Environm

Fleet Inventory & Vehicle Registration

Verify the completeness and accuracy of the active fleet vehicle register for the reporting period.

Is a complete fleet vehicle register maintained listing all company-owned and long-term leased vehicles?
Does each vehicle record include vehicle identification number (VIN), fuel type, model year, and engine size?
Have any vehicles been added or removed from the fleet during the reporting period, and has the register been updated?
Are third-party contracted vehicles (grey fleet) included or explicitly excluded with documented justification?
What is the total number of active vehicles in the fleet during this reporting period?

Fuel Consumption Data Collection

Collect, verify, and validate fuel consumption data across all fleet vehicles and fuel types.

Has fuel consumption data been collected from all active fleet vehicles for the full reporting period?
Are fuel consumption records sourced from fleet card systems, fuel receipts, or fuel management software?
Is fuel consumption recorded separately by fuel type (diesel, petrol, CNG, LPG, HVO, electric)?
What was the total diesel consumed by the fleet during the reporting period (litres)?
What was the total petrol/gasoline consumed by the fleet during the reporting period (litres)?
Are any fuel data gaps present, and if so, have estimation methods been applied and documented?

Emissions Calculation & Emission Factors

Verify correct emission factors and calculation methods are applied to fleet fuel consumption data.

Are EPA 40 CFR Part 98 Table C-1 or IPCC/DEFRA emission factors being used for mobile combustion calculations?
Are CH4 and N2O emissions calculated separately and converted to CO2 equivalents using current GWP values?
For electric vehicles in the fleet, is electricity consumption tracked and reported as Scope 2 emissions?
What is the total calculated Scope 1 fleet emissions for the reporting period (MT CO2e)?
Has an emissions intensity metric (CO2e per km or CO2e per tonne-km) been calculated for benchmarking?

Odometer & Distance Records

Verify mileage and distance data for fleet vehicles to support distance-based emission calculations and compliance verification.

Are odometer readings or telematics distance records collected for all fleet vehicles each month?
Is total distance driven recorded separately by vehicle class (light-duty, heavy-duty, etc.)?
What was the total fleet distance travelled during the reporting period (km)?
Are any telematics or GPS systems used to automate distance and fuel efficiency data collection?
Are there any vehicles with missing or implausible odometer readings that require investigation?

Vehicle Maintenance & Emissions Compliance

Confirm vehicles are maintained to manufacturer standards and meet applicable emissions compliance requirements.

Are all fleet vehicles current with scheduled maintenance to maintain optimal fuel efficiency and emissions performance?
Have any vehicle emissions tests or roadworthiness inspections been completed and are certificates on file?
Are refrigerated transport units (TRUs) monitored separately for fuel consumption and emissions where applicable?
Are any diesel particulate filter (DPF) or AdBlue system faults recorded and remediated promptly?
Provide notes on any vehicles with outstanding maintenance issues affecting emissions performance?

Fleet Decarbonization & EV Transition Tracking

Monitor progress toward fleet electrification and fuel switching targets in line with SBTi and corporate climate commitments.

Does the organization have a fleet decarbonization or electrification target with a defined target year?
What percentage of the current fleet consists of zero-emission vehicles (BEV, FCEV)?
Are low-carbon alternative fuels (HVO, biomethane, hydrogen) being tracked for use and emission factor adjustments?
Is a fleet replacement schedule maintained that prioritizes highest-emitting vehicles for early replacement?
Has the fleet achieved year-over-year improvement in average CO2e per km intensity?

Data Reporting, Audit Trail & Record Keeping

Confirm fleet emissions data is documented, traceable, and ready for internal or third-party audit.

Are all fuel purchase receipts, fleet card statements, and telematics exports retained in an auditable document system?
Has monthly fleet emissions data been reconciled against year-to-date totals for consistency?
Is fleet emissions data integrated into the organization's central GHG inventory management system?
Has this reporting period's fleet emissions data been reviewed and signed off by a responsible manager?
Provide any additional notes on data quality issues, anomalies, or corrective actions taken this period?
Upload supporting documentation or fuel data export for this reporting period?
