Collection figures, recycled content and rental contracts describe different activities. Credible circular economy claims connect those activities to measured outcomes, fair comparisons, and the consumer rules now applying in the EU.
A company can collect more products without returning more useful material to production. It can increase recycled content while selling substantially more material overall. It can replace sales with subscriptions while adding transport and cleaning. None of these possibilities makes circular business models inherently ineffective. They show why the claim must identify the change being measured.
This is a practical issue for research teams, manufacturers and buyers. A promising intervention needs a measure that reveals whether it works, while a customer needs enough context to understand the benefit. When the same percentage is used for collection, recycling and environmental improvement, information is lost at each step.
A stronger approach starts with the product or service delivered, follows the relevant material flows and compares the environmental consequences. It allows a company to report a useful improvement without implying that every aspect of its business has become sustainable.
A percentage needs a clearly defined denominator
Consider a hypothetical take-back scheme that reports collecting 80% of eligible products. That figure raises several questions. Does eligibility refer to products sold in the same year, products reaching an estimated end of life or customers enrolled in the programme? Are returned accessories included? The number can be accurate while answering a narrower question than a reader assumes.
The next stage needs its own account. Some collected products may be reused, others dismantled, and others rejected. A recovered component may enter another product, while a sorted material may still fail a buyer’s specification. Recording these transitions makes the result more useful than presenting the collection rate as the fraction successfully recycled.
Mass is also only one perspective. Preserving a small functional component can have a different value from recovering a larger quantity of low-grade material. An evaluation should state the intended outcome and use measures appropriate to it, rather than assume that the heaviest stream necessarily represents the greatest benefit.
For repeated reporting, the method should remain comparable. If the eligible population or measurement boundary changes, the company should explain the effect on its trend. Otherwise, an apparent improvement could arise from a new calculation rather than better physical performance.
Lifecycle comparisons reveal trade-offs
The Commission’s Environmental Footprint methods build on life-cycle assessment and cover 16 environmental impact categories. They combine general methods with product or sector rules intended to support comparisons between similar activities. Climate impact is one category alongside pressures associated with resources, water, land and other effects.
A useful comparison therefore needs an equivalent function. Comparing one reusable container with one disposable container would miss the service delivered over repeated uses. Comparing materials without accounting for the amount required to achieve the same performance could be equally misleading. The reference should reflect what the customer needs, not simply the object that is easiest to count.
Assumptions about lifetime, recovery and replacement deserve particular attention. A longer technical life only creates the expected benefit if the product remains in use. A high potential recycling rate matters differently from a measured recovery rate. Publishing sensitivity to these assumptions helps identify which operational conditions must hold for the claimed advantage to materialise.
Lifecycle analysis is a structured comparison, not a guarantee that every effect has been measured perfectly. The relevant uncertainties should remain visible when the result moves from a research report into a sales presentation.
A service contract is a mechanism rather than a result
A December 2025 Joint Research Centre case study examined a handheld vacuum cleaner offered through a subscription model. Its material-flow comparison used a 100% return rate for the service scenario against 41% for purchased products, alongside higher component extraction and reuse. The analysis found lower material requirements under its assumptions. These are results for a specified case, not observed return rates guaranteed by every subscription contract.
The example identifies what needs to be tested in another business. Does ownership retention actually bring products back? Are components suitable for another life? Does maintenance extend useful service? A rental model that achieves these outcomes has a different environmental account from one that replaces stock frequently or relies on extensive transport.
The OECD’s analysis of circular business models also identifies uncertainty about rebound effects, where changes in costs or behaviour offset part of an expected environmental saving. Its discussion supports examining the consequences of greater consumption as well as efficiency per use. It does not establish that rebound eliminates every circular benefit.
An assessment should therefore retain both scales: performance per unit of service and total activity. A more efficient offer can be a real improvement while the business’s overall resource demand still rises. Reporting both gives customers and managers a clearer basis for judgement.
The new consumer rules are already applying
The EU’s Empowering Consumers for the Green Transition Directive had a national transposition deadline of 27 March 2026, with application from 27 September 2026. That application date has passed. The Commission now identifies the amendments as applicable within the unfair commercial practices framework; businesses must consider the relevant national implementation.
The amended blacklist addresses generic environmental claims without recognised excellent environmental performance relevant to the claim, sustainability labels not based on an appropriate certification scheme or established by public authorities, and whole-product or whole-business claims based on only one aspect. It also prohibits claiming, on the basis of emissions offsets, that a product has a neutral, reduced or positive environmental impact in terms of greenhouse gas emissions. These rules concern defined commercial practices, not a ban on communicating every specific, substantiated environmental improvement.
In June 2026, consumer enforcement authorities agreed a common understanding on old stock. The Commission describes possible phased enforcement where genuine transitional difficulties arise, alongside an expectation of timely, good-faith adaptation. This is not a blanket exemption for old packaging or a postponement of the application date.
The practical implication is to review the impression created by the complete communication. A narrowly accurate footnote may not explain a broad headline, image or label clearly enough. Evidence should be connected to the claim where the audience encounters it.
A pending proposal is different from current law
The separate Green Claims Directive proposal concerns substantiation and communication of explicit environmental claims. As checked in October 2026, the Commission’s official page still labels its status as pending. Proposed verification arrangements should therefore not be presented as enacted requirements already applying to every claim.
That distinction does not create an evidence-free interval. Existing consumer law and the newly applicable amendments already matter. A company can also choose a relevant established scheme: the Commission explains that EU Ecolabel criteria are product-group-specific, consider lifecycle performance and are reviewed over time. A licence relates to the applicable criteria, not an unlimited endorsement of every company activity.
For technical teams, the stronger habit is to define the statement before commissioning the calculation. Specify the product, comparison, time period and outcome. Then ask whether the available evidence supports that statement, rather than assemble a broad claim around whichever favourable number happens to be available.
Keep the evidence connected to the decision
A practical claim record would retain the calculation, source data, assumptions and version of the product assessed. It would identify who can approve changes and what triggers a reassessment, such as a new material supplier or a different recovery route. This turns substantiation into an ongoing business process. It also gives commercial teams a clear point at which to pause a claim if a supplier, manufacturing process or collection arrangement changes.
The most useful reporting would also explain shortfalls. A lower-than-expected return rate or a rejected recycling fraction can identify where the next intervention belongs. Concealing those losses behind a single circularity score deprives operational teams of information they need to improve.
Credible circular economy claims do not need to promise perfection. They need to say what changed, how it was measured and where the conclusion applies. That precision makes genuine progress easier to recognise and gives the next customer or research team something concrete to test.
