Product Carbon Footprint and LCA Data in PLM
A product carbon footprint (PCF) is the total greenhouse gas emissions of a product across its life cycle or a defined part of it, expressed in kilograms of CO2 equivalent per unit. It is calculated with life cycle assessment (LCA) methods such as ISO 14067. PLM provides the bill of materials, material and process data a PCF requires.
Key takeaways
- ISO 14067, the GHG Protocol Product Standard and the PACT Methodology are the main PCF frameworks, with PEF used for broader EU environmental footprints.
- EU law increasingly requires product-level footprints, starting with EV batteries and expected for iron and steel under ESPR.
- Since 27 September 2026, claims of climate neutrality based on offsetting alone are banned for consumer products in the EU.
- Accurate PCFs depend on PLM bill of materials data combined with supplier-specific primary emission data.
How a product carbon footprint is calculated
A PCF follows the life cycle assessment logic: define the functional unit and system boundary, build an inventory of inputs and outputs, multiply quantities by emission factors and sum the results. Two boundaries dominate in practice:
- Cradle-to-gate: raw material extraction through to the product leaving the factory. This is the usual basis for business-to-business data exchange.
- Cradle-to-grave: adds distribution, use phase and end of life. It is common for consumer products and energy-using equipment, where use-phase emissions can dominate.
The main methods are ISO 14067:2018, the GHG Protocol Product Life Cycle Standard and, for data exchange between companies, the PACT Methodology published by WBCSD (version 3 released April 2025). Sector rulebooks such as the Catena-X PCF rulebook for automotive and the Together for Sustainability guideline for chemicals add specific allocation rules. The EU Product Environmental Footprint (PEF) method, set out in Commission Recommendation (EU) 2021/2279, covers 16 impact categories, of which climate change is one.
Which EU rules require product footprint data?
| Instrument | Footprint requirement | Status (October 2026) |
|---|---|---|
| Batteries Regulation (EU) 2023/1542 | Carbon footprint declaration and later classes for EV, LMT and industrial batteries | Pending methodology delegated act; not before late 2027 for EV batteries |
| ESPR (EU) 2024/1781, iron and steel | Carbon footprint information and possible performance classes | Delegated act expected Q4 2026 |
| CBAM, Regulation (EU) 2023/956 | Embedded emissions of imported steel, aluminium, cement, fertilisers, hydrogen, electricity | Definitive period since 1 January 2026; first annual declaration due 30 September 2027 |
| CSRD and ESRS E1 | Company-level Scope 3, which product footprints can feed | Simplified ESRS from FY2027 |
| Empowering Consumers Directive (EU) 2024/825 | Restricts generic environmental claims and offset-based neutrality claims | Applies since 27 September 2026 |
The CBAM simplification Regulation (EU) 2025/2083 introduced a 50-tonne annual threshold below which importers are exempt. The proposed Green Claims Directive, which would have required prior verification of claims, has been on hold since the Commission announced its intention to withdraw it in June 2025. See ESPR, the EU battery passport and CSRD and product data for the wider context.
Which data does a PCF need from PLM?
| Data | Source | Notes |
|---|---|---|
| Bill of materials with quantities and units | PLM | Basis for the material inventory |
| Material type and grade per part | PLM, material library | Links each part to an emission factor |
| Mass per part (net and gross) | PLM, CAD | Includes production scrap |
| Recycled and bio-based content | Supplier declarations | Affects emission factors |
| Supplier PCF values (primary data) | Supplier portals, PACT exchange | Preferred over database averages |
| Manufacturing process steps and energy use | MBOM, routing, MES | Plant-specific electricity mix |
| Packaging | Packaging specifications | Often captured for PPWR |
| Use-phase energy and lifetime | Product specifications | Relevant for cradle-to-grave |
| Emission factor dataset and version | LCA tool | Needed for audit trail |
The share of primary data, the dataset version and the calculation date should be stored with each result, because customers and auditors increasingly ask for data quality indicators. In typical manufacturing portfolios, purchased materials and components account for the majority of cradle-to-gate emissions (estimate, varying widely by sector), so supplier-specific data has the largest effect on accuracy. Where primary data is missing, secondary data from databases such as ecoinvent fills the gap and should be flagged as such.
Integrating LCA with PLM
Three integration patterns are common. Some organisations export the bill of materials to a standalone LCA tool and import results back as attributes. Others use LCA functions embedded in PLM, which allow designers to compare footprints of alternatives during development. A third approach uses a dedicated carbon data platform connected to PLM, ERP and supplier networks. Enterprise suites such as Dassault Systèmes 3DEXPERIENCE and Siemens Teamcenter offer embedded sustainability analysis, and fashion PLM such as Centric Software integrates material impact data.
Whatever the pattern, PCFs should be versioned with the product revision, so a design change triggers recalculation through engineering change management. Results then flow to customers through PACT-compatible exchange, to sustainability reporting for Scope 3, and to passports where a delegated act requires footprint information.
Frequently asked questions
What is the difference between a PCF and an LCA?
A life cycle assessment evaluates several environmental impact categories across a product's life, such as climate change, water use, acidification and resource depletion. A product carbon footprint is a single-issue assessment limited to greenhouse gas emissions, expressed in CO2 equivalent. A PCF can be derived from a full LCA, and standards such as ISO 14067 build on the ISO 14040 and 14044 LCA framework.
Is a product carbon footprint mandatory in the EU?
Not generally. Mandatory product footprints arise from specific laws, starting with EV, LMT and industrial batteries under Regulation (EU) 2023/1542 once the methodology delegated act applies, and iron and steel under ESPR when its delegated act is adopted. CBAM requires embedded emission data for certain imported goods. Many companies also calculate PCFs voluntarily for customer requests and Scope 3 reporting.
Can products still be marketed as carbon neutral?
Since 27 September 2026, the Empowering Consumers Directive (EU) 2024/825 bans claims that a consumer product has a neutral, reduced or positive climate impact based on greenhouse gas offsetting alone. Claims based on actual reductions across the product life cycle remain possible if substantiated. National consumer authorities enforce these rules, so companies should review existing labels and product content.
