What Is ISO 14067 Verification?

ISO 14067 verification is an independent review of a product carbon footprint report, calculation method, product system boundary, life cycle stages, functional or declared unit, activity data, emission factors, assumptions, allocation rules, exclusions, uncertainty, and supporting evidence.

The objective is to determine whether the reported product carbon footprint information is complete, consistent, traceable, and materially correct against the agreed verification criteria.

Verification does not only check the final carbon footprint value. It reviews the reliability of the information behind the product carbon footprint, including source records, product data, calculation files, boundary decisions, emission factor references, allocation methods, and internal review of the product carbon footprint report.

Verified Product Carbon Footprint Statement

ISO 14067 is used for product-level quantification and reporting of the carbon footprint of products. It provides a structured basis for defining the product, functional or declared unit, product system boundary, life cycle stages, calculation methods, emission factors, assumptions, allocation rules, and product carbon footprint reporting.

Who Needs ISO 14067 Verification?

ISO 14067 verification is useful for organizations that need credible, independently reviewed product-level carbon footprint information.

Manufacturers

Verification of product carbon footprint reports for manufactured goods, production processes, materials, packaging, and product-level carbon claims.

Product Life Cycle Boundary in ISO 14067 Verification

Product carbon footprint verification may consider different life cycle stages depending on the product, intended use, system boundary, data availability, and selected criteria. The product boundary should clearly define which stages are included, which are excluded, and how assumptions and limitations are justified.

Raw Materials and Inputs

Emissions associated with raw materials, ingredients, components, packaging materials, purchased goods, and upstream supplier data used in the product.

Manufacturing and Processing

Emissions related to production processes, energy use, fuel consumption, process activities, production yield, waste generation, and on-site operations.

Packaging and Storage

Emissions associated with product packaging, secondary packaging, storage conditions, refrigeration, warehousing, and handling activities.

Transport and Distribution

Emissions related to inbound logistics, outbound distribution, transportation modes, distances, loads, fuel use, and delivery assumptions.

Use and End-of-Life (Where Applicable)

Emissions associated with product use, maintenance, disposal, recycling, recovery, landfill, incineration, or other end-of-life treatment depending on the product category and defined boundary.

The verification scope should clearly define the product, functional or declared unit, system boundary, included life cycle stages, excluded processes, allocation rules, assumptions, and data quality requirements.

Searching for an ISO 14067 Certificate?

Many organizations search for an “ISO 14067 certificate” or “ISO 14067 certification” when they need formal evidence that a product carbon footprint report has been independently verified.
In practice, ISO 14067 is used for product carbon footprint quantification and reporting. It is not used in the same way as a traditional management system certification standard such as ISO 9001. Therefore, the appropriate output is usually a product carbon footprint verification statement, verification report, or product carbon footprint verification certificate, depending on the agreed verification scope and criteria.
WECERT supports organizations that need independent verification evidence for ISO 14067 product carbon footprint reports, customer requirements, product-level carbon claims, supply-chain requests, procurement submissions, export markets, and sustainability communication.
