AI-generated editorial illustration; not an actual certification or test.
“Circular” is useful only when a business explains what happens to its products and materials. A collection scheme, repair service or recycled component can be a starting point, but none alone proves that an entire business has closed every resource loop. Standards provide a vocabulary and a measurement structure for more precise decisions.
Which ISO documents answer which questions?
ISO’s circular-economy catalogue identifies ISO 59004:2024 for vocabulary, principles and implementation guidance; ISO 59010:2024 for business-model and value-network transitions; and ISO 59020:2024 for measuring and assessing circularity performance. They serve related purposes and should not be treated as interchangeable labels.
Read the scope and publication status before purchasing or specifying a document. A reference in a sales presentation is not evidence that the company has measured its performance or obtained a relevant certification.
Define the system before choosing a number
ISO 59020 addresses measurement within defined economic systems, including boundaries and indicators. That helps expose a common problem: a percentage calculated for one component can be mistaken for a claim about an entire product or company. Keep the unit, period and included processes visible.
Consider this hypothetical example: a business repairs reusable delivery boxes. Counting the boxes repaired is useful, but a fuller assessment would also record how many return, how long they remain usable and what happens to damaged material. This is an illustration of questions to ask, not a reported company case study or a formal application of the standard.
Build a small, auditable record
- Name the product or service and the problem you want to address.
- Map incoming materials, use, returns and outgoing material.
- Select indicators and record their definitions.
- Keep source data, assumptions and exclusions together.
- Compare later results on the same basis and explain changes.
Circularity and environmental impact are different assessments
A circularity measure does not answer every question about energy, water, emissions or social effects. ISO 14044 describes requirements for life-cycle assessment. Use an appropriate additional assessment when a claim concerns overall environmental impact rather than material flows alone.
What changed in this article?
We removed broad company success stories that were not supported by adequate evidence here and replaced them with a clearly labelled example. We also updated the standards overview. No standard is presented as automatic proof of legal compliance, guaranteed savings or an entirely sustainable product.
