Sustainability and carbon3 / 5

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.

A retired ice pack is two parts: the plastic shell and the fill. The shell goes to recycling by its material mark; the safety data sheet decides the route of the fill.

Set carrying capacity from the actual bike and box ratings. On a route trial, monitor product conditions, cooling packout and stops.

Add parts lists, service procedures and fault records to bid comparisons. Do not assume parts availability or service life.

Define where it fits from route, energy, product and return data instead of forecasting.

Record discarded quantity and cause by step, then test one change against your own data.

Define the boundary, service life and allocation method; document electricity, fuel, equipment and waste data by source.

Assess passive transport with actual route, load, waiting and product readings, not assumed battery range.

Define the boundary and reporting unit first, then collect transport, energy, packaging, and loss data for the same period.

Measure per-shipment quantities by material and weighing method, while tracking product protection.

Check product requirements and name those responsible for acceptance, transport, and handover. Batch and time records clarify custody.

Do not treat a score as product certification or a rating for every legal entity. Check scope, date and current evidence.
