Introduction

Product Carbon Footprint, or PCF, is the quantified greenhouse gas emissions associated with a single product across its lifecycle, calculated according to ISO 14067’s requirements for consistency with ISO 14040 and ISO 14044 life cycle assessment principles. In 2026, PCF stops being a voluntary sustainability exercise and becomes a market access requirement under the EU Battery Regulation and the Ecodesign for Sustainable Products Regulation. Companies that sell into the EU, or that supply companies with EU reporting obligations, need a defensible, ISO 14067 aligned PCF methodology in place now.

Key Takeaways

• ISO 14067:2018 governs how a product’s carbon footprint is quantified and reported, covering only the climate change impact category, and excludes carbon offsetting and CFP communication, which fall under the separate ISO 14026 standard.
• Under the EU Battery Regulation (2023/1542), rechargeable industrial batteries above 2 kWh require a carbon footprint declaration from 18 February 2026, with mandatory labeling from 18 August 2026 and QR code accessibility from 18 February 2027.
• The Ecodesign for Sustainable Products Regulation (2024/1781) makes the Digital Product Passport mandatory across product categories from 2026 through 2030, with iron and steel as the first priority group with an indicative 2026 delegated act.
• ASUENE’s platform connects PCF calculation directly to Scope 3 Category 1 reporting, since a supplier’s product carbon footprint effectively becomes the buyer’s purchased goods and services emissions data.
• The WBCSD’s PACT Methodology, now in version 3.0, is the interoperability layer that lets ISO 14067 aligned PCF data move between trading partners in a standardized, machine-readable format.

What Is ISO 14067 and What Does It Require Companies to Do?

ISO 14067:2018 sets the principles and requirements for quantifying and reporting a product’s carbon footprint, consistent with the broader ISO 14040 and ISO 14044 life cycle assessment standards. It addresses only one impact category, climate change, and excludes offsetting and CFP communication.

Related standards fill in the rest of the picture:

• ISO 14026 governs how a company communicates CFP results, including labels and claims.
• ISO 14064-3 sets requirements for validating and verifying GHG statements, including product carbon footprints.
• ISO 14065 defines the competence and impartiality requirements for the bodies that carry out that verification.

A common executive mistake is treating a PCF study as automatic license for a “carbon neutral” claim. ISO 14067 covers quantification only; ISO 14026 governs the claim itself.

ISO’s technical committee has also published a working draft, ISO/WD 14067.2, intended to replace the 2018 edition while keeping the same core scope. A confirmed publication date was not available in the sources reviewed, so companies should monitor ISO’s committee pages directly.

Why Is Product Carbon Footprint Now a Regulatory Requirement in 2026?

Three EU files convert PCF from a voluntary exercise into a market access requirement:

• The EU Battery Regulation requires carbon footprint declarations for specific battery categories starting in 2026.
• The Ecodesign for Sustainable Products Regulation, through the Digital Product Passport, requires verified environmental data, including carbon footprint, for an expanding list of product categories between 2026 and 2030.
• Both regulations reference Product Environmental Footprint methodology and life cycle assessment principles that overlap substantially with ISO 14067, so one ISO 14067 aligned PCF capability can largely be reused across obligations.

EU Battery Regulation Carbon Footprint Declaration Deadlines

Regulation (EU) 2023/1542 requires certain battery categories to carry a carbon footprint declaration when placed on the EU market. Staged deadlines by battery type, each 12 or 18 months after the relevant delegated or implementing act enters into force, whichever comes later:

The declaration states carbon footprint as CO2 equivalent per kWh of total energy delivered over the battery’s expected service life. Until it becomes accessible via QR code, mandatory from 18 February 2027, the declaration must physically accompany the battery. The European Commission has also confirmed that a greater than 10 percent increase in a battery’s calculated emissions, due to material, sourcing, or process changes, triggers a recalculation and a new declaration.

Digital Product Passport and ESPR: Carbon Footprint as a Market Access Requirement

Regulation (EU) 2024/1781 entered into force in July 2024, extending ecodesign scope from energy related products to nearly all physical goods placed on the EU market, including imports. The European Commission’s April 2025 Working Plan for 2025 to 2030 sequences priority product groups:

Each delegated act defines the disclosure requirements for its product group, and the Digital Product Passport is the mechanism through which that data, including carbon footprint, becomes accessible. The compliance clock starts group by group rather than on a single date, and iron and steel manufacturers face the earliest pressure.

How Does ISO 14067 Compare to PEF, EPD, and the PACT Methodology?

Executives often conflate four distinct concepts:

PCF vs. LCA vs. Corporate Carbon Footprint: Key Differences

Summing PCFs across a portfolio does not produce a corporate footprint. The two follow different accounting boundaries, and PCF work should feed into, rather than replace, corporate GHG inventory management.

How Can a Supplier’s PCF Become a Buyer’s Scope 3 Category 1 Data?

Purchased goods and services, Scope 3 Category 1, is typically the largest emissions category in a manufacturer’s inventory. Aggregating verified supplier PCFs, rather than relying on spend-based industry averages, is the most accurate way to calculate it. This is the gap the WBCSD’s PACT Methodology addresses.

PACT Methodology v3.0 (April 2025) and Technical Specifications v3.0.3 (November 2025) define the calculation rules, data model, and API that let a supplier’s PCF flow directly into a buyer’s Scope 3 Category 1 disclosure. This matters for companies with CSRD or IFRS S2 obligations, which face growing pressure to move beyond spend-based estimation as assurance requirements tighten.

Version tracking matters too: PCFs calculated under PACT v2 before 30 April 2025 remain valid for three years, provided the underlying process has not changed materially. A greater than 10 percent emissions change, similar to the Battery Regulation’s threshold, triggers an earlier recalculation.

Building an ISO 14067-Aligned PCF Program: A Practical Roadmap

Treat PCF as infrastructure, not a one-time study. Cradle-to-gate, covering raw material extraction through the factory gate, is the standard B2B boundary and the scope required by the WBCSD PACT Framework for supply chain data exchange, making it a practical starting point even without an immediate regulatory trigger.

Three priorities in sequence:

1. Align internal data collection with ISO 14067 from the outset, so one study can support both PEF-based Battery Regulation declarations and DPP-based ESPR disclosures.
2. Build the capacity to exchange PCF data through a PACT-conformant system, since customers increasingly request this format rather than static reports.
3. Put a recalculation trigger in place, tied to the Battery Regulation’s 10 percent materiality threshold or an equivalent internal control, so PCF data stays current as production and supply chains change.
