Product carbon footprint (PCF): a guide for businesses
Direct answer
A product carbon footprint (PCF) is the total greenhouse gas emissions of a single product across its life cycle, expressed in kilograms of CO2 equivalent. The calculation adds up the emissions from raw materials, production, transport, use and end-of-life treatment. Where a corporate footprint measures the emissions of an entire organisation, the PCF zooms in on one product, which makes comparison and improvement possible per product.

Product carbon footprint (PCF): scattered information versus Energy Intelligence
More and more Dutch suppliers receive a questionnaire from a large customer: how much CO2 is embedded in the product you deliver to us? That question is not driven by curiosity. Large buyers must account for their value chain emissions and can only do so with figures from their suppliers. Whoever has a substantiated answer ready keeps the customer relationship strong and passes supplier assessments. This affects manufacturers, component suppliers and wholesalers, from manufacturing to food production.
- The two authoritative accounting frameworks are ISO 14067 and the GHG Protocol Product Standard, both based on the life cycle assessment rules in ISO 14040 and 14044.
- The system boundary determines the outcome: cradle-to-gate stops at the factory gate, cradle-to-grave also includes use and disposal. Always state the boundary alongside the figure.
- The demand comes from the supply chain: customers reporting under the CSRD or with climate targets through the Science Based Targets initiative need your product figures for their own value chain emissions.
Insight
Traditional approach
Information is scattered across portals, documents, invoices or separate spreadsheets.
Modern approach
Data, context and interpretation are brought together into a clear decision picture.
Decision-making
Traditional approach
Choices are made based on averages, assumptions or occasional analyses.
Modern approach
Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.
Follow-up
Traditional approach
Actions often stay non-committal or disappear into separate reports.
Modern approach
Follow-up actions, monitoring and reporting are linked to the same energy data.
How do you calculate a product carbon footprint?
You first define which product you calculate and which unit you use, for example one kilogram or one packaged end product. You then map the emissions per life cycle stage: raw material extraction, supply, your own production, transport, use and end-of-life treatment. Each activity is multiplied by an emission factor and the results are added up to kilograms of CO2 equivalent per unit of product. The two common accounting frameworks are ISO 14067 and the GHG Protocol Product Standard. Both build on the life cycle assessment (LCA) rules in ISO 14040 and 14044. The difference with a full LCA: a PCF limits itself to a single environmental impact, climate change. The European Product Environmental Footprint (PEF) covers a broader set of environmental impacts, of which climate is one.
- Choose a clear unit of calculation, for example per kilogram or per item.
- ISO 14067 and the GHG Protocol Product Standard are the common frameworks.
- A PCF is a life cycle calculation limited to climate change.
- Your own measured data (primary data) makes the figure stronger than database averages.
When will you encounter it?
The demand for product figures almost always comes from outside. Large customers that fall under the European CSRD reporting obligation must also account for the emissions in their supply chain, so they ask suppliers for product data. Companies with climate targets through the Science Based Targets initiative must include their value chain emissions in those targets once these exceed 40 percent of their total emissions; they too turn to their suppliers. If you trade in steel, cement, fertilisers, aluminium, hydrogen or electricity, the European CBAM affects you directly: importers pay for the CO2 emissions released during the production of those goods and need per-product emission data for that. In the Netherlands, the NEa and Customs implement CBAM. The CO2 performance of products also carries growing weight in public tenders.
- Customers under the CSRD need your product figures for their value chain reporting.
- SBTi targets must cover value chain emissions once these exceed 40 percent of the total.
- CBAM applies to imports of steel, cement, fertilisers, aluminium, hydrogen and electricity.
- CBAM applies from 2026; importers need authorised declarant status, while the annual declaration and certificates follow from 2027.
Where do you start and what are the pitfalls?
Start with one product that customers frequently ask about or that carries a large share of your revenue. Then determine the boundary: cradle-to-gate calculates up to your factory gate and is often sufficient for business-to-business deliveries; cradle-to-grave also includes use and disposal. ISO 14067 explicitly recognises such a partial calculation as a partial carbon footprint. The biggest pitfall is supplier data: without figures from your suppliers you fall back on database averages, and those hide your actual improvements. So ask your key suppliers for their own figures. The second pitfall is comparability: two PCFs are only comparable with the same boundary, unit and accounting rules. Always state those choices alongside the figure and document your assumptions, so the calculation remains verifiable and reusable for future customer requests.
- Start with the product customers ask about most often.
- Cradle-to-gate stops at the factory gate; cradle-to-grave includes use and disposal.
- Request your key suppliers' own figures instead of relying only on database averages.
- Only compare PCFs with an identical boundary, unit and accounting rules.
- Record assumptions and sources, so the figure remains verifiable.
