Why the Environmental Footprint method matters
Before the EF method, two honest assessments of the same product could produce very different numbers simply because they used different impact models. That made comparison meaningless and environmental claims hard to trust. The EF method fixes the rules, covering categories, factors, and data quality requirements, so results become comparable. This is precisely why the EU has been building EF into regulation, from battery carbon footprints to EPDs and Digital Product Passports.
What the Environmental Footprint method covers
The EF method assesses environmental impact across a defined set of categories, 16 in the current EF 3.1 version, spanning climate change, acidification, eutrophication, freshwater ecotoxicity, human toxicity, resource depletion, water use, and land use. It prescribes how to model the product or organisation, which characterisation factors to apply, and how to assess and report data quality through the Data Quality Rating. The most recent version, EF 3.1, aligns climate change with IPCC AR6 factors.
PEF versus OEF
The two strands answer different questions. The Product Environmental Footprint (PEF) measures the impact of a specific product or service, guided by Product Environmental Footprint Category Rules (PEFCRs) for particular product groups. The Organisation Environmental Footprint (OEF) measures the impact of an entire organisation's activities. Most regulatory and customer-facing work in industrial supply chains uses PEF, because the unit of interest is a product.
EF, PEF, and EF 3.1: clearing up the terms
These terms are often used loosely. "EF method" is the overall framework. "PEF" is the product-level application of it. "EF 3.1" is the current version number of the method, defining the specific impact categories and characterisation factors in force. A practitioner producing a regulated footprint works within the EF method, applies the PEF approach to their product, and uses the EF 3.1 factors.
The Environmental Footprint method and regulation
The EU Battery Regulation's carbon footprint methodology is built on the PEF method and its category rules. EPDs are increasingly expected to use EF factors. Digital Product Passports will carry EF-based data. For any company producing a regulated environmental figure in the EU, the EF method is the foundation the numbers must stand on.
