Product Carbon Footprint (PCF): What It Is and How It Connects to the DPP
What a product carbon footprint (PCF) is, how it is calculated under ISO 14067 and the PEF method, how it differs from a corporate carbon footprint, which EU regulations require it, and how the Digital Product Passport carries the PCF to consumers and regulators.
Product Carbon Footprint (PCF): What It Is and How It Connects to the DPP
Key takeaways
A product carbon footprint (PCF) is the total amount of greenhouse gases emitted across the life cycle of a single product, expressed in kilograms of CO2 equivalents (kg CO2e). It is calculated with life-cycle assessment (LCA) methods and standardised through ISO 14067 and the EU Product Environmental Footprint (PEF) method. A PCF is not the same as a corporate carbon footprint (CCF), which measures an entire organisation over a year. The PCF is quickly becoming a regulated data point: the EU Battery Regulation already mandates a carbon footprint declaration, the ESPR allows the Commission to require it inside the Digital Product Passport (DPP), and the EmpCo Directive forces any “climate neutral” or “CO2-reduced” claim to be backed by real data. The DPP does not calculate your PCF, but it is the vehicle that stores and communicates the verified value to consumers, regulators, and recyclers.
If you want to start with the basics of the passport itself, we recommend the introductory article Digital Product Passport in 15 minutes: what a DPP is and why the EU is introducing it.
What is a product carbon footprint?
A product carbon footprint is the sum of all greenhouse gas emissions and removals associated with a product over its defined life cycle. It is reported in a single figure: kilograms of CO2 equivalents (kg CO2e). The “equivalents” part matters, because a PCF does not only count carbon dioxide. It also converts other greenhouse gases such as methane and nitrous oxide into their warming impact relative to CO2, using globally agreed factors.
The PCF is a product-level metric. It answers the question “how much climate impact does one unit of this specific product cause?” rather than “how much does our company emit in a year?”. That distinction is the source of most confusion in practice, so it is worth being explicit about it.
Product carbon footprint vs corporate carbon footprint
Two footprints are routinely confused because both are measured in CO2 equivalents:
- Product carbon footprint (PCF): emissions attributed to one product unit, from raw materials through manufacturing, distribution, use, and end of life. It is the basis for product-level claims, eco-labels, and — increasingly — the Digital Product Passport.
- Corporate carbon footprint (CCF): emissions of an entire organisation over a reporting period, usually a year, structured into Scope 1, Scope 2, and Scope 3 emissions. It is the basis for corporate reporting under frameworks such as the CSRD.
The two are connected: a company’s Scope 3 emissions are, in effect, an aggregation of the footprints of the products it buys and sells. But a regulator asking for a PCF in a Digital Product Passport wants the per-product figure, not the annual corporate total.
How is a product carbon footprint calculated?
A PCF is the output of a life-cycle assessment (LCA) focused on climate impact. The calculation follows four broad steps, standardised by ISO 14040 and ISO 14044 for LCA in general and by ISO 14067 specifically for carbon footprints of products:
- Define the goal and system boundary. Decide which life-cycle stages are included (see below) and the “functional unit” — for example, one pair of shoes or one kilogram of packaging.
- Collect life-cycle inventory data. Gather the energy, materials, transport, and processes involved at every included stage, drawing on both primary (supplier) data and secondary (database) data.
- Assess the impact. Convert each input into greenhouse gas emissions and express them in kg CO2e using recognised characterisation factors.
- Interpret and report. Document assumptions, data quality, and the system boundary so the figure is verifiable and comparable.
System boundaries: cradle-to-gate vs cradle-to-grave
The single most important thing to check about any PCF is its system boundary, because two figures are only comparable if they cover the same stages:
- Cradle-to-gate: from raw-material extraction to the factory gate. It excludes distribution, use, and disposal. This is common for intermediate products and business-to-business declarations.
- Cradle-to-grave: the full life cycle, including transport, the use phase, and end-of-life treatment. This is the most complete boundary and the one most relevant to consumer-facing claims.
Recognised standards and methods
- ISO 14067 — the international standard specifically for the carbon footprint of products.
- PEF (Product Environmental Footprint) — the EU’s own methodology (Commission Recommendation 2021/2279), used across many EU sustainability instruments, of which climate change is one impact category.
- GHG Protocol Product Standard — a widely used product-level accounting standard.
- EN 15804 — the reference for environmental product declarations (EPDs) of construction products.
Which method applies is increasingly dictated by regulation: EU product rules tend to point to ISO 14067 or PEF.
Which EU regulations require a product carbon footprint?
The PCF is moving from a voluntary marketing figure to a legally required data point. Four regulatory strands matter:
1. EU Battery Regulation — the first mandatory PCF
The Battery Regulation (EU) 2023/1542 is the first EU product law to make a carbon footprint declaration mandatory. It applies in sequence: first to electric-vehicle batteries, then to rechargeable industrial batteries above 2 kWh, and later to light-means-of-transport (LMT) batteries. Each declaration must follow a Commission methodology and be carried in the battery passport — itself a form of Digital Product Passport. The exact application dates depend on delegated and implementing acts, whose adoption has been progressively finalised rather than arriving all at once, so the precise cut-off per battery type should always be checked against the current EU acts.
2. ESPR and the Digital Product Passport
The Ecodesign for Sustainable Products Regulation (ESPR, Regulation (EU) 2024/1781) is the horizontal framework that decides what data a DPP must contain, product group by product group. Carbon footprint is one of the information requirements the Commission can set, expressed in kg CO2e at specific life-cycle stages and calculated per ISO 14067 or the PEF method. As delegated acts for the first product groups (batteries, textiles, electronics) take effect, the PCF becomes a passport field rather than an optional disclosure.
3. EmpCo Directive and green claims
The EmpCo Directive (Directive (EU) 2024/825), which applies from 27 September 2026, bans generic environmental claims that are not backed by evidence and specifically restricts “climate neutral” claims that rely only on offsetting. In practice, any climate-related product claim now needs a defensible PCF behind it. For the full picture, see our article on the Green Claims Directive and the DPP.
4. CBAM and CSRD (the wider context)
The Carbon Border Adjustment Mechanism (CBAM) puts a price on the embedded emissions of certain imported goods, and the CSRD requires corporate sustainability reporting that increasingly rests on product-level data. Neither mandates a consumer-facing PCF directly, but both raise the value of having reliable, per-product carbon data ready to reuse.
A product carbon footprint example
To make the figure concrete, here is a simplified, illustrative breakdown of where the emissions of a product typically arise (values are examples, not benchmarks):
| Life-cycle stage | Share of PCF | Typical drivers |
|---|---|---|
| Raw materials | 40–60% | Metals, plastics, textiles, chemicals |
| Manufacturing | 15–30% | Energy mix of the factory, process losses |
| Distribution | 5–15% | Transport mode and distance, packaging |
| Use phase | 0–40% | Energy consumed while in use (high for appliances) |
| End of life | 2–10% | Recycling, incineration, or landfill |
The lesson from almost every PCF study is the same: for most non-powered products, the raw materials and manufacturing stages dominate, which is exactly why material composition and supplier data — the same data a DPP already collects — are decisive.
Why the PCF and the Digital Product Passport belong together
The Digital Product Passport and the product carbon footprint draw on the same underlying product data: bill of materials, material shares, suppliers, origin, energy, and end-of-life route. Rather than maintaining that data twice, a DPP lets you record it once and reuse it.
- The carbon footprint declaration required by the Battery Regulation is a passport field.
- A “CO2 reduced” or recycled-content claim under the EmpCo Directive needs the same evidence the DPP already stores.
- Consumers, regulators, and recyclers can reach the verified figure through the QR code / GS1 Digital Link that fronts the passport.
There is an important honesty caveat: a Digital Product Passport — and myDPP — does not calculate your PCF. That figure is the result of an LCA, produced with dedicated LCA software or a consultant and, where required, independently verified. What the passport does is carry, version, and communicate the resulting value in a structured, auditable way, so the same number serves compliance, procurement, and marketing without being re-keyed.
Preparing your product carbon footprint: five steps
1. Define scope and boundary
Decide the functional unit and whether you report cradle-to-gate or cradle-to-grave, and record the choice explicitly. Comparability depends on it.
2. Map your data sources
List where each input comes from — ERP, PIM, supplier declarations, energy meters — and identify the gaps you will need to fill with secondary data.
3. Calculate under a recognised standard
Run the LCA under ISO 14067 or the PEF method, using appropriate software or an external specialist, and keep the assumptions documented.
4. Verify where required
For regulated declarations such as the battery carbon footprint, arrange the third-party verification the rules demand before publishing the figure.
5. Store the PCF in your product data foundation
Record the verified figure, its boundary, and its calculation date alongside your other product data, so it can flow into the Digital Product Passport and into any environmental claim.
Frequently asked questions (FAQ)
What is a product carbon footprint in simple terms?
It is the total greenhouse gas emissions caused by one unit of a product across its life cycle, expressed in kilograms of CO2 equivalents (kg CO2e).
How is a product carbon footprint calculated?
Through a life-cycle assessment focused on climate impact, standardised by ISO 14067 or the EU PEF method. You define a system boundary, collect life-cycle data, convert it to CO2 equivalents, and report the result with its assumptions.
What is the difference between a product and a corporate carbon footprint?
A product carbon footprint (PCF) covers one product unit; a corporate carbon footprint (CCF) covers an entire organisation over a year, split into Scope 1, 2, and 3 emissions.
Is a product carbon footprint mandatory in the EU?
For some products, yes. The EU Battery Regulation already requires a carbon footprint declaration, and the ESPR lets the Commission require a PCF inside the Digital Product Passport for further product groups.
Does a Digital Product Passport replace the LCA?
No. The passport does not calculate the footprint — an LCA does. The DPP carries, versions, and communicates the verified figure so it can be reused for compliance and claims.
