How is PEF different from a general LCA?

PEF is LCA-based but provides harmonized EU rules intended to improve consistency, comparability, reproducibility, and verifiability.

A Product Environmental Footprint Category Rule provides more specific modeling and reporting rules for a defined product category.

Can two PEF results always be compared?

No. Meaningful comparison requires compatible scope, methods, data quality, category rules, and intended use; the study documentation should explain comparability.

Does CommonShare perform independent verification?

No. It helps organize inputs, calculation context, results, and review evidence. Under the PEF method, verification and validation are mandatory when a study or part of it is used for external communication; an appropriate independent reviewer must perform that work.

PEF, made operational.

Make environmental results transparent by preserving the study data and decisions behind them.

Product Environmental FootprintVoluntary environmental methodologyVoluntary methodology · used by EU policy and market initiatives

Product Environmental Footprint is the EU’s life-cycle-assessment method for measuring a product’s environmental impacts. It is not a standalone regulation, but it provides harmonized rules that can support product policy, claims, procurement, and category-specific comparisons.

Method design

Frame a PEF study before collecting activity data.

PEF is a voluntary EU methodology, not a standalone compliance duty. Define the goal, scope, functional unit, system boundary, category rules, and intended use before modelling results.

Define goal and scope

Set the functional unit, system boundary, intended application, audience, and methodological choices.

Build the life-cycle inventory

Collect product, supplier, process, energy, transport, use, and end-of-life activity data.

Calculate environmental impacts

Apply prescribed impact categories, characterization factors, allocation rules, and data-quality methods.

Interpret and document

Identify material contributors, test sensitivity, state limitations, and prepare the required report.

Verify external communications

Arrange verification and validation when the study or part of it is used for external communication, and apply any stricter policy or PEFCR rules.

Regulatory workflow in practice

Move from scope to a governed outcome.

Map the relevant records, collect evidence, review gaps, and release an approved outcome with a complete history.

CommonShare support

Make product-impact calculations traceable to source data.

CommonShare supports activity-data collection, governed calculation context, supplier-specific improvements, and review evidence. Independent verification remains separate.

Traceable activity data

Connect calculation inputs to products, materials, suppliers, sites, periods, and source documents.

Governed calculation context

Maintain units, methods, assumptions, factors, versions, and review status alongside results.

Supplier-specific improvement

Replace estimates with primary data through structured requests and quality checks.

Reusable impact evidence

Use approved product-impact data in ESPR, product passports, procurement, and substantiated communications.

Frequently asked

PEF studies, category rules, verification, and comparability

No. PEF is an EU methodology, not a standalone binding regulation. It can, however, be referenced by policies, schemes, contracts, or market initiatives.
