Free fleet resource
Build a baseline you can explain.
Learn why fleet carbon comparisons need a genuine baseline, a consistent reporting period and explicit distance and powertrain assumptions.
Save the starting position
A baseline records the fleet’s position at a defined time. Keep fleet size, powertrain mix, distance sources, reporting period and method version together. Without that context, two numbers can tell a misleading story.
Wait for the evidence
The supplied method permits a year-on-year change only when a snapshot around 12 months old exists to calculate it from. Until then, use “Baseline is building”. Do not substitute a forecast or invented percentage.
Explain what changed
A reduction in total emissions may reflect fewer vehicles, reduced activity, different inputs or a real operational improvement. Make the relevant changes visible rather than treating every reduction as efficiency.
Keep estimates distinguishable
Replacing default mileage with better data can change the carbon figure even if the fleet’s activity has not changed. An explicit default helps readers understand that shift.
Connect the claim to the record
When you communicate a self-assessed tier, keep its code or public verification link attached. Include the period and method in the underlying record and check its current status.
