Road fleet pathway

Methodology architecture begins with comparability.

CAP uses a conservative measurement design for fuel efficiency. Verra VMR0004, Improved Efficiency of Fleet Vehicles, Version 2.0, is a target methodology for road vehicles and mobile machinery only, subject to formal eligibility confirmation.

Target pathway

Road fleet CAP eligibility and readiness gates.

The gates below are design requirements for CAP’s internal review. Passing them does not create registration, approval or credits.

1. Qualifying efficiency intervention

Document that LVEP Engine Oil is a qualifying low-viscosity engine-oil intervention for the eligible engine population and that the project concerns vehicle or mobile-machinery efficiency, rather than operational changes alone. Confirm OEM requirements, performance specification, ambient conditions, duty cycle, warranty considerations and oil-analysis safeguards.

2. Defined assets and comparable service

Assign each participating vehicle or mobile machine to a defined category. Match baseline and project services by route or duty-cycle class, fuel type/blend, payload proxy, speed/idle conditions and maintenance condition. Exclude or adjust materially non-comparable periods.

3. Carbon rights and regulatory surplus

Contractually establish ownership of emission reductions and environmental attributes. Document that claimed reductions are beyond mandatory requirements and assess applicable host-country, regional and net-zero policy interactions.

4. Additionality and common practice

Complete investment analysis or a qualifying implementation-barrier analysis and assess whether the measure is common practice in the relevant market. Keep supporting evidence in the project audit file.

5. Monitoring precision and periods

Define project and baseline periods, collection controls, uncertainty treatment and exclusions. Monitoring systems must meet the precision and confidence expectations of the ultimately accepted methodology and verification plan.

Baseline selection

Three controlled baseline options.

Choose the approach that makes the comparison auditable, not simply convenient.

Telematics-supported historical baseline

Use vehicle-level historical data with documented route/duty-cycle stratification, fuel reconciliation, maintenance review and cutover controls.

Readiness floor

At least 5,000 kilometres of pre-intervention operating data or 200 engine/operating hours, unless an approved sampling procedure applies.

Matched control group

Maintain a comparable non-LVEP group. Match engine family, asset class, route, duty cycle, payload, fuel, maintenance and operating conditions.

Control discipline

Explain matching logic, drift controls, removals and exceptions. Do not compare unlike services.

Approved sampling approach

Use a documented sampling plan where full-population monitoring is not feasible, subject to methodology requirements for precision, confidence and representativeness.

Approval needed

Sampling must be reviewed against the ultimately accepted methodology; it is not presumed acceptable.

Pilot boundary: a four-week informal trial can support technical feasibility or pilot learning. It is not automatically sufficient for carbon-credit issuance, validation or verification.

MRV data standard

Every reporting number should trace back to a source record.

Primary data: each fueling event

Vehicle ID; date/time; fuel litres; odometer or engine-hour reading
Fuel type and biodiesel blend; fueling station or depot
Driver/operator where available; route or duty-cycle category
Vehicle-level reconciliation to depot or supplier totals

Required supporting evidence

LVEP brand/specification, grade, API/OEM evidence and batch/lot
Oil-change date, volume, top-ups and relevant oil analysis
Maintenance, downtime, breakdowns, tyres, injectors, DPF and route changes
Telematics: speed, idle, traffic, harsh events, payload/load proxy and temperature where available

Calculation engine

Fuel intensity is the calculation anchor.

CAP supports several operational metrics. Select a metric that represents the service delivered, apply the same unit in both periods, then retain all assumptions and exclusions.

Operation type	Primary metrics	Fuel savings logic	Required comparability
Distance-based road fleet	L/km, L/100 km, km/L	(Baseline L/km − Project L/km) × project km	Route, load, fuel, driving cycle, maintenance
Idle-heavy or mobile machinery	L/engine-hour, alongside L/100 km where possible	(Baseline L/hour − Project L/hour) × project hours	Operating hours, load, idle, task, maintenance
Freight service	L/tonne-km where reliable payload data exist	Intensity reduction × project tonne-km	Payload, route, distance, vehicle and service
Maritime (separate pathway)	L/nautical mile; L/tonne-nautical-mile where relevant	Subject to maritime modelling and methodology confirmation	Vessel performance, speed, draft/payload, weather, auxiliary load

Fuel saved

Δ intensity × service

Use project-period service as the multiplier after checking comparability and exclusions.

Estimated CO2 avoided

Fuel × factor ÷ 1,000

Use only a documented factor with value, source, publication date, geography, fuel/blend treatment and approver.

QA/QC and uncertainty

Conservativeness is a control, not a slogan.

Validate records

Flag negative distance, zero distance with material fuel, declining odometers, duplicate entries, implausible fuel volumes, missing IDs, missing dates and inconsistent fuel blends.

Protect comparability

Track route reassignment, major engine repair, tyre and injector work, DPF events, unusual idling, downtime and missing maintenance data. Stratify, model or exclude as justified.

Report uncertainty

Show vehicle-level results, mean, median, range and, where feasible, confidence intervals. Apply conservative treatment where evidence is incomplete.

Claims boundary

Formal determination sits outside a dashboard.

CAP calculator label: “Screening and operational reporting calculation. Formal credit issuance calculations must follow the accepted methodology and registry requirements.”

Potential next reviewers

Methodology specialists, competent independent reviewers, validation/verification bodies, registry/standard representatives and relevant government authorities may each have a role based on the selected pathway.

Reference frameworks

Potential reference points include GHG Protocol Project Accounting; ISO 14064-2, ISO 14064-3, ISO 14065 and ISO/IEC 17029; IPCC principles; and the selected program’s requirements. Referencing a framework is not an endorsement or acceptance.
