Do not compare an intensity value alone. Show its functional unit, system boundary, load and route mix alongside it.

Link shipment code to route, load, activity data and method. If using a period average, state its allocation and limits clearly.

Explain period, boundary, data source and allocation method alongside results. Verify the requested reporting format with the customer and applicable standard.

The tonne-kilometre is the unit of transport work: how much load carried how far. ISO 14083 defines load mass and distance separately, and if the distance is measured differently the unit changes with it.

Keep traction and refrigeration energy separate. Compare them through tank stock, operating mode, electricity and passive preparation records.

Choose an allocation key that reflects load use and reporting purpose; disclose data sources and method consistently.

An empty leg may carry no freight but still uses fuel. Record distance, fuel and allocation method, then explain the result.

Measured data and default factors have different bases. Make the source, scope and data gaps visible on every calculation line.

TTW counts emissions released at the vehicle, WTT the production and supply of the energy, and WTW the sum of both. ISO 14083 and the GLEC Framework work from the total.

Match meter, activity and cargo records for the same period; disclose the allocation key and excluded items in the report.

A TCE boundary is drawn where the vehicle or the transfer point changes, and a TOC groups similar trips over a period of up to one year. How these two decisions are made changes the result directly.

Define the boundary and activity data before calculating; document sources, periods and estimates together.

The depot should accept a dirty container, wash it on a separate line and record the soiling by store. Sending it back keeps the problem on the road for another round.

Measure actual footprint and stack height for empties. Verify nesting compatibility in model instructions and discuss return frequency using those data.

Match issue and return counts by store, container ID and date. Surface differences the same day; a deposit alone does not show location.

Do not assume a savings percentage. Compare purchase, energy, labour, loss and actual usage over the same period.
