ISO 14020 and environmental statements explained

ISO 14020 is the international standard that sets the principles and general requirements every environmental statement about a product has to meet, from a claim printed on a pack to an ecolabel or an environmental product declaration.

Its 2022 edition replaced a document people still quote by its old name, and changed both the vocabulary and the rules.

The words most of us still use here are the ones ISO retired. Type I, Type II and Type III are all deprecated in the 2022 edition, and so is "environmental claim" as a catch-all term.

The facts on ISO 14020

Here is the short version of what the document is and where it came from.

ISO 14020 is the core document of a family of seven standards. The other six each take one type of statement and give it detailed rules, so this one is written to be read alongside them rather than on its own.

What an environmental statement actually is

An environmental statement is information about the environmental aspects or impacts of a product, put out to inform someone and influence the market for that product. In plainer words, anything you tell a buyer about what your product does to the environment.

That is broader than it sounds. It covers a word on a label, a symbol, a logo, a QR code, a line in a web shop and a line in an advert.

Two other terms carry real weight in the 2022 edition, and the rest of the standard leans on both.

1. The responsible party. Whoever is responsible for providing the statement. Usually the supplier, but the standard explicitly names a distributor, a marketer and even a social media influencer.
2. The intended audience. Whoever the responsible party has identified as relying on that statement to make a decision, such as a purchaser, an investor or a regulator.

The 2022 edition also renamed the four kinds of statement. If you have used the Type I, Type II and Type III labels for years, this is the translation.

The word "claim" has not disappeared, it has been narrowed. It now refers only to a self-declared claim, the kind you make about your own product with nobody else signing it off.

How the 2022 edition rewrote the 2000 one

The 2000 edition was guidance and said so. It set out nine principles, numbered Principle 1 to Principle 9, and stated outright that it was not intended as a specification for certification purposes.

Principle 1 asked that labels be accurate, verifiable, relevant and not misleading. Good intent, nothing behind it.

The 2022 edition kept the principles, grew them to ten, then did what the old one never did. It pulled the requirements out of the principles and gave them two clauses of their own, one for programmes and one for statements. The picture below is the shape of that change.

Two of the four changes ISO lists in its foreword are about language. Two new concepts arrived, the environmental statement and the environmental statement programme, along with definitions that hold across every type of statement instead of only inside one standard.

The ten principles behind every environmental statement

Clause 4 carries ten principles, each written as a short principle followed by the reasoning behind it. They apply to every type of statement in the family.

1. Credibility. The reason anyone acts on a statement at all.
2. Evidence-based methodology. The 2022 wording for the old scientific-methodology principle.
3. Transparency and availability. The method behind a statement should be findable.
4. Confidentiality. Transparency has a limit where commercially sensitive data is concerned.
5. Life cycle perspective. Look at the whole product, not one convenient stage.
6. Environmental performance improvement and innovation. Statements should pull the market forward.
7. Accessibility and avoidance of unnecessary information and administrative demands. Do not bury the reader or the supplier.
8. Interested parties and consultation. Programmes get built with the people they affect.
9. Voluntary. Nothing in ISO 14020 is compulsory of itself.
10. Regionality. What counts as environmentally significant differs by place.

Two of those are easy to misread. Voluntary means the standard imposes nothing by itself, which is not the same as nobody being able to require it of you. Confidentiality is there so a supplier is not forced to publish a recipe in order to back up a statement.

What ISO 14020 requires

The requirements sit in two separate clauses, and it helps to know which one you are in. Clause 6 governs the programme behind a statement. Clause 7 governs the statement itself.

Requirements for the programme

The biggest change for a producer is that ISO 14020 expects every environmental statement, including one you declare yourself, to be made inside an environmental statement programme.

That sounds heavy, and the standard says plainly it need not be. A programme can be an extensive set of scheme rules or a simple internal process, and Annex A gives a worked example of the simple kind.

Whatever its size, a programme has an identifiable owner or operator, and that owner settles five things up front.

1. Which type of statement the programme covers.
2. The requirements, criteria and method behind it.
3. Who assesses it, and whether that is you or an outside party.
4. The format and media it gets communicated in.
5. How long it stays valid, and any ongoing checks.

Clause 6 then adds requirements on consulting interested parties, on data quality and reporting, on conformity assessment, and on what happens when the rules change.

Requirements for the statement itself

Clause 7 is the one that reaches the wording on your packaging. It gives general requirements, then takes the five cases that cause the most trouble one at a time.

1. Vague or non-specific statements.
2. Statements of sustainability.
3. Comparative statements that set your product against someone else's.
4. The supporting information you give alongside a statement.
5. The use of symbols and graphics.

Read that list again and it is a map of how greenwashing actually happens. Vague wording, an unqualified sustainability claim, a comparison with no stated basis, a symbol that implies more than it says.

Who ISO 14020 is written for

Two groups, and most producers are in the first. If your team decides what goes on a pack, in a product listing or in a tender response, ISO 14020 describes the discipline behind that wording.

If you run a scheme other companies apply to, an ecolabel or an EPD programme, clause 6 is aimed straight at you.

An example makes the split concrete. A drinks brand printing "made with 50% recycled plastic" is a responsible party making a self-declared claim, so ISO 14021 gives them the detailed rules while ISO 14020 gives them the principles and the programme expectation.

The body running the EU Ecolabel sits on the other side of the line. They are a programme operator, so clause 6 governs how they run the scheme.

Where ISO 14020 meets the PPWR rules on environmental claims

The EU's Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, applies from 12 August 2026 and gives environmental claims an article of their own. Article 14 is short and it bites in two places.

1. You may only claim what you beat. Where the regulation already sets a legal requirement on a packaging property such as recyclability, recycled content or reusability, you can claim that property only if your packaging exceeds the minimum required, measured by the regulation's own methods. Hitting the legal minimum is not something you get to advertise.
2. You have to say what the claim covers. Namely the packaging unit, part of it, or all packaging you place on the market. Compliance is demonstrated in the Annex VII technical documentation, the same file behind your EU declaration of conformity.

Here is the honest limit. PPWR never names ISO 14020, so following the standard is not compliance with Article 14 and it will not move an EPR fee. What it gives you is a defensible method for the part the law leaves open, which is how a statement was substantiated and how carefully it was worded.

Consumer law is moving the same way through Directive (EU) 2024/825, which applies from 27 September 2026 and restricts generic green wording and self-invented sustainability labels.

How ISO 14020 relates to the rest of its family

ISO 14020 sets the common ground and each of the others takes it from there.

The rename did not stop with ISO 14020. New editions of ISO 14024, ISO 14021 and ISO 14025 all arrived in 2026, each taking the same "environmental statements and programmes for products" title and dropping Type I, Type II and Type III from its own cover.

The old numbering is now gone from the whole family, not just from the core document.

One confusion is worth clearing up because it comes up constantly. ISO 14001 is the certifiable standard in this neighbourhood, and it covers how you manage your organisation, not what you say on a product. ISO 14020 has no certificate attached to it at all.

Frequently asked questions about ISO 14020

Short answers to what people ask most about the standard.

What is ISO 14020?

ISO 14020 is the international standard setting the principles and general requirements for every environmental statement made about a product, from self-declared claims to ecolabels and environmental product declarations. It is the core document of its family, currently in the 2022 edition.

Is ISO 14020 a certification?

No. There is no certificate for ISO 14020 and no auditor issues one. You conform to it and reference it. Conformity assessment does appear in the standard, but as something a programme does to a statement, not something a body does to your company.

What edition of ISO 14020 is current?

The 2022 edition, published in December 2022 as the third edition. It cancelled and replaced ISO 14020:2000, which is now withdrawn. In Europe the identical text is published as EN ISO 14020:2023.

What changed in the 2022 edition of ISO 14020?

Four things. The title changed, and two new concepts arrived, the environmental statement and the environmental statement programme. The principles grew from nine to ten, and general requirements were added in two clauses the 2000 edition never had.

Is it still correct to talk about Type I and Type II labels?

Everyone will know what you mean, but ISO 14020 marks those terms as deprecated. The current wording is ecolabel for Type I, self-declared environmental claim for Type II, and environmental product declaration for Type III.

Is ISO 14020 mandatory?

No. One of its ten principles is that it is voluntary, and no EU packaging law names it. Even so, PPWR Article 14 and Directive (EU) 2024/825 both regulate environmental claims directly, so the substance it asks for is increasingly required by law anyway.

Do I need a programme just to put a recycled content claim on my packaging?

Under ISO 14020 yes, but a programme can be a simple internal procedure rather than a scheme you join. Write down the claim, the criteria and method behind it, who checks it and how long it holds. Annex A shows that lightweight example.
