CONSULTING

Product carbon footprint

Start with one product. Build a footprint you can explain.

Build an assessment around a product life-cycle boundary, activity data and relevant factors to identify hotspots and respond to customer data requests.

Start with the functional unit

Define function, use scenario and accounting unit. Distinguish full-life-cycle needs from assessments with a specific boundary.

Connect supply-chain data

Organize materials, manufacturing, energy and transport records. Document treatment of gaps, assumptions and limitations.

Make results explainable

Discuss relevant frameworks such as ISO 14067 or the GHG Protocol, and support report preparation and verification coordination.

Begin with the customer's question

Procurement, product development and environmental communication use footprints differently. Confirm the model, function, accounting unit, market and customer request before calculation. Carbonstop connects life-cycle accounting with supply-chain evidence to explain product hotspots. Defining the purpose also helps identify any relevant product-category rules, reporting format or assurance needs. It avoids completing an assessment only to discover that the customer wanted a different boundary or a different basis for comparison.

Organize records along the life cycle

Depending on the agreed boundary, the checklist can cover materials, supplier production, manufacturing, packaging, transport, use and end-of-life. A bill of materials needs quantities, units, sources and the relevant product version. Factory energy needs to connect to production and processes. Use scenarios require documented assumptions. Where several products share a process, the model must explain resource and emissions allocation rather than dividing all factory totals equally across the product range.

Make the model reflect the product

Model review can examine process routes, losses, recycled inputs, transport assumptions and factor applicability. Supplier-specific records should be distinguishable from database values, with gaps and estimates documented. Exploring important assumptions helps identify those with the greatest effect on the result. This gives purchasing and product teams a practical indication of which primary records are worth obtaining next, while preserving a calculation trail for reporting and future product updates.

Use the result to investigate improvements

The scope can include a collection checklist, model description, footprint report and hotspot analysis. Material substitutions, process changes and packaging options can be explored against consistent functions and boundaries. Comparing versions requires separating design changes from updated data or factors; a changed model is not automatically an achieved reduction. The report can support customer communication and label preparation, with assurance or certification needs determined by its intended use.

Choose a pilot that can be reused

For a large product range, start with a model that has a clear business request, available records and representative production conditions. A pilot can establish templates before the team considers how other products reuse the approach. Bring specifications, the bill of materials, output, energy, transport information and the customer's questionnaire, identifying the current version. This supports the immediate assessment while creating a practical starting point for the next update.

PREPARE THE CONVERSATION

A useful starting point
for the discussion.

Start with available records and a list of gaps. Agree on scope and outputs after reviewing the actual situation.

FAQ

Questions before you decide.

Can a product family share one result?

Shared records and models can be discussed, but differences in function, materials, manufacturing and use may affect results. Define which models each result covers. Membership of the same product family alone does not establish that one footprint represents every version.

Is a cradle-to-gate result a full-life-cycle assessment?

No. A factory-gate boundary normally excludes later stages such as use and end-of-life. State the boundary and purpose clearly. If the customer needs the full life cycle, the assessment needs the relevant additional scenarios and records.

What if suppliers cannot provide footprint records?

Review material and purchasing information, consider suitable secondary data and document its source, representativeness and uncertainty. Prioritize supplier collection for materials with a greater emissions influence, rather than treating every missing record as equally significant.
