Developed by the European Commission, PEF provides a science-based, comparable framework that helps companies substantiate environmental claims, avoid greenwashing, and align with the broader objectives of the EU's Green Deal. According to the European Commission, the PEF methodology is specifically designed to ensure credibility and transparency in [environmental](https://www.fiegenbaum.solutions/en/blog/effective-esg-storytelling-startups-investors-customers?hsLang=en) claims, addressing the growing scrutiny from both regulators and consumers. In a market increasingly sensitive to sustainability credentials, PEF offers companies a defensible, standardized way to demonstrate their environmental performance. PEF is still a voluntary method in most sectors, but that is shifting. With sector-specific rules such as the Battery Regulation building on it, PEF [compliance](https://www.fiegenbaum.solutions/en/blog/lca-vs-pcf-environmental-assessment-guide?hsLang=en) is becoming a reference point for battery market access and for credible sustainability communication. Companies that act now gain a strategic head start, those that wait risk non-compliance penalties and lost market opportunities. PEF data also shows where in the life cycle the impacts sit, which can point to process optimization. **Table of Contents** 1.

While a traditional LCA under ISO 14044 gives practitioners flexibility to define system boundaries, choose impact categories, and select datasets, PEF eliminates most of that discretion through product-specific Category Rules (PEFCRs). The result is an assessment that is far more comparable across companies and products, but also more demanding to execute correctly. **Live data:** the Fiegenbaum Atlas provides PV module, heat pump and cleantech prices, updated automatically. [Open the dashboard](https://atlas.fiegenbaum.solutions/en/loesungspreise?utm_source=fiegenbaum-solutions&utm_medium=blog&utm_campaign=atlas-loesungspreise&utm_content=eu-product-environmental-footprint-pef-guide). The table below shows where the two approaches diverge: | Aspect | EU PEF | Traditional LCA (ISO 14044) | | --- | --- | --- | | Methodological Flexibility | Highly restricted, governed by PEFCRs | Flexible, practitioner-defined | | Comparability | High, standardized across products | Variable, different approaches possible | | Data Requirements | Strictly defined (EF-compliant datasets only) | Less stringent, practitioner discretion | | EU Legal Status | Commission Recommendation (EU) 2021/2279; mandatory basis only for the Battery Regulation carbon footprint | Voluntary | | Impact Categories | 16 defined categories with normalization and weighting | Selected by practitioner | | Public Claims Verification | Recommended; required by law only where sector rules demand it | Not required (but recommended) | ## The 16 PEF Impact Categories One of the defining features of PEF is that it assesses environmental performance across 16 distinct impact categories, not just carbon emissions. This breadth prevents companies from optimizing for one metric (e.g., CO₂) while inadvertently worsening others (e.g., water use or land degradation). The eight most material categories for the majority of industrial product groups are shown below: | Impact Category | What It Measures | | --- | --- | | Climate Change | Greenhouse gas emissions (CO₂ equivalent) | | Ozone Depletion | Damage to the stratospheric ozone layer | | Human Toxicity (cancer & non-cancer) | Health impacts from chemical emissions and exposure | | Resource Use, Fossils | Depletion of non-renewable energy resources | | Water Use | Freshwater consumption and regional scarcity | | Land Use | Soil quality degradation and occupation | | Particulate Matter | Fine particle emissions affecting respiratory health | | Eutrophication (freshwater & marine) | Nutrient pollution in water bodies | Each category is calculated, normalized against a European reference value, and weighted to produce an [aggregated PEF score](https://eur-lex.europa.eu/eli/reco/2021/2279/oj). It is important not to equate this score with a carbon footprint alone, PEF is a multi-dimensional environmental indicator, and presenting it as a single CO₂ number is both technically incorrect and a potential compliance risk under the Empowering Consumers Directive and national unfair competition law. ## Product Category Rules (PEFCRs): The Foundation of PEF Product Environmental Footprint Category Rules (PEFCRs) are the product-specific rulebooks that govern how a PEF study must be conducted for a given product group. Each PEFCR defines the system boundary, data quality requirements, the most relevant impact categories for that product group, default use-phase scenarios, and the specific calculation rules that must be followed. Without the applicable PEFCR, a PEF study cannot be considered complete or verifiable. PEFCRs were developed through multi-year EU pilot projects involving industry stakeholders, scientific experts, and the [European Commission's Joint Research Centre (JRC)](https://eplca.jrc.ec.europa.eu/EnvironmentalFootprint.html). PEFCRs from the EU pilot and transition phases exist for sectors including batteries, detergents and several food and feed products such as dairy, pet food and animal feed; the Commission lists apparel and footwear among the newer PEFCRs. Other categories, including packaging, electronics and construction materials, are at various stages of [development](https://www.fiegenbaum.solutions/en/blog/integrating-trl-lca-early-sustainable-product-development?hsLang=en). Before starting a PEF study, always verify the applicable PEFCR on the European Commission's official PEFCR registry. If no finalized PEFCR exists for your product, you must apply the general PEF methodology, which requires additional methodological judgment and documentation, and may be subject to revision when the PEFCR for your category is eventually finalized. ## The PEF Process: 5 Key Steps Implementing PEF for your product follows a structured process. Below is a condensed overview of the five core steps: 1. **Identify the applicable PEFCR**: Confirm which product category rules apply to your product. This step determines your system boundary, functional unit, key impact categories, and data requirements. If no finalized PEFCR exists, apply the general PEF methodology and document your methodological choices carefully. 2. **Collect primary and secondary data**: Gather activity data from your own operations and supply chain (primary data). Supplement with EF-compliant secondary datasets from the [European Platform on Life Cycle Assessment (EPLCA)](https://eplca.jrc.ec.europa.eu/) or the Life Cycle Data Network (LCDN). Only validated, EF-compliant datasets are accepted, using non-compliant data is one of the most common reasons PEF studies fail verification. 3. **Model and calculate environmental impacts**: Use PEF-compatible LCA software (e.g., SimaPro or openLCA) to calculate impacts across all 16 categories. Apply the normalization and weighting factors defined in the PEF methodology to generate the aggregated PEF score. 4. **Interpret results and identify hotspots**: Analyze which life cycle stages and impact categories drive your environmental footprint. For many products, particularly electronics and appliances, the use phase dominates. For textiles, raw material sourcing is often the primary hotspot. These findings are the basis for credible environmental claims and targeted improvement actions. 5. **Verify, report, and update**: PEF studies used for public claims should be verified by an independent third party; there is no general legal duty, but verification is the strongest defence if a claim is challenged. Establish internal data collection routines so the study can be updated regularly, PEF is designed as a continuous improvement tool, not a one-time project. Companies that treat PEF as an ongoing process rather than a compliance checkpoint gain the most strategic value. ## PEF and EU rules on green claims The [EU Green Claims Directive](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52023PC0166) (proposed in 2023) would have required environmental claims made in the EU market to be substantiated using a recognized scientific methodology, without prescribing PEF. In June 2025 the Commission announced its intention to withdraw the proposal, and the trilogue has been on hold since. What applies from 27 September 2026 is Directive (EU) 2024/825, which bans generic environmental claims without proof of recognised excellent performance and product claims of climate neutrality based on offsetting. It does not prescribe PEF either. The proposal would have exposed companies making claims such as "sustainable," "eco-friendly," "green," or "low carbon" without proper substantiation to [fines of at least 4% of annual turnover in the Member States concerned](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52023PC0166) for widespread infringements, claim corrections and temporary exclusion from public procurement. None of that is law today; current enforcement runs through national unfair commercial practices rules as amended by Directive (EU) 2024/825. PEF provides documented, independently verified evidence that helps defend claims before those authorities. For sectors where finalized PEFCRs already exist, such as batteries and detergents, companies making environmental claims should consider a PEF study as substantiation now, even though no law requires it. For other sectors, a finalized PEFCR is the point at which PEF-based claims become comparable. Early preparation is the most cost-effective strategy. ## Practical Tips for Companies Starting with PEF - **Start with your highest-impact or highest-visibility product**: Choose a flagship product for your first PEF study. This builds internal expertise, generates the most strategically valuable data, and delivers the most credible environmental communication to customers and investors. - **Use only EF-compliant datasets**: Non-compliant secondary data is one of the most common reasons PEF studies fail verification. Verify dataset compliance before modeling begins, not at the end. - **Involve your [supply](https://www.fiegenbaum.solutions/en/blog/carbon-stress-tests-business-resilience-co2-compliance?hsLang=en) chain early**: Primary data from key suppliers significantly improves the accuracy of your PEF study and reduces reliance on generic secondary data. Begin supplier data collection conversations as early as possible. - **Do not treat PEF as a one-time project**: Build annual data collection routines from the outset. PEF results become more valuable, and more defensible, when they can show improvement over time. - **Distinguish PEF results from a carbon footprint in all communications**: A PEF score reflects 16 impact categories. Presenting it as a simple CO₂ figure is technically incorrect and creates regulatory risk under the Empowering Consumers Directive. - **Seek expert support for verification**: Third-party verification is not generally required by law, but it is what makes a public claim defensible. Engaging an experienced consultant early avoids costly rework at the verification stage and shortens the path to market-ready claims. ## Frequently Asked Questions 1\. Is PEF mandatory for all companies in the EU? No. PEF is a Commission Recommendation (EU) 2021/2279. The one binding use so far is the EU Battery Regulation, whose carbon footprint declaration for electric vehicle and industrial batteries is calculated on a PEF basis once the methodology act applies. The Green Claims Directive, which would have referenced PEF, was not adopted. Battery manufacturers face the earliest deadlines. Companies in electronics, food, and construction have more time but should begin preparation now given the complexity of a full PEF study. How this plays out in practice: [Digital Battery Passport and LCA Requirements: Implementation Guide for EU Battery Regulation 2023/1542](https://www.fiegenbaum.solutions/en/blog/eu-battery-regulation-digital-product-passport-lifecycle-assessment?hsLang=en). 2\. How long does a PEF study take? A full PEF study for a single product typically takes 3 to 9 months, depending on data availability, supply chain complexity, and whether a finalized PEFCR exists. Companies with well-structured internal data and experienced external support can work toward the lower end of that range. Verification adds additional time and should be planned for from the outset. 3\. Can SMEs conduct PEF studies? Yes. The European Commission has developed simplified guidance and toolkits specifically for small and medium-sized enterprises. Industry associations in several sectors also provide shared secondary datasets and training materials to reduce the cost and complexity of compliance for smaller companies. Sector-level initiatives and collective PEF programs are emerging in apparel and food as practical entry points for SMEs. 4\. What is the difference between PEF and an Environmental Product Declaration (EPD)? Both are based on LCA methodology, but they serve different purposes and markets. EPDs (based on ISO 14025 and EN 15804) are widely used in the construction and infrastructure sector for B2B procurement and tender processes. PEF is the methodology the Commission recommends for product-level environmental footprints. An EPD does not automatically count as a PEF study, so check which of the two the customer or the applicable rule actually asks for. ## Conclusion: Act Now to Stay Ahead of PEF Requirements The EU Product Environmental Footprint is still a recommended methodology, with the Battery Regulation as its first binding use. Companies that begin PEF compliance now, identifying applicable PEFCRs, building data collection infrastructure, and conducting their first studies, will be better positioned to substantiate environmental claims, access EU procurement markets, and meet incoming regulatory deadlines without disruption. Waiting until enforcement arrives is a high-risk strategy. Penalties for misleading environmental claims under national consumer law are real, and the lead time for a credible, verified PEF study is measured in months. The companies that build PEF capability today will use it as a competitive differentiator tomorrow, in procurement processes, investor communications, and consumer-facing sustainability claims.
