SIST EN ISO 14020:2024/oprA1:2026 is a CEN draft amendment to ISO 14020 on environmental statements and programmes for products. It updates the shared principles and general requirements used for self-declared environmental claims, ecolabels, environmental product declarations (EPDs) and footprint communications, so suppliers, programme operators and buyers can use the same basic language and checks.

What does SIST EN ISO 14020:2024/oprA1:2026 specify?

SIST EN ISO 14020:2024/oprA1:2026 updates the common principles and general requirements for environmental statements for products and the programmes that support them. The amendment is organized as replacement text for the Introduction and selected definitions in Clause 3.

The updated Introduction explains the purpose of environmental statements, the role of programme operators, and the place of ISO 14020 within the ISO/TC 207/SC 3 family of documents. The Clause 3 changes refine the meanings of core terms such as environmental statement, self-declared environmental claim, EPD, ecolabel and verification.

What are the key requirements of SIST EN ISO 14020:2024/oprA1:2026?

SIST EN ISO 14020:2024/oprA1:2026 keeps the focus on trustworthy environmental communication. Its key messages are that statements must be accurate, transparent and based on documented, scientifically sound assessment methods, because vague or deceptive claims can mislead the market.

The main principles in the updated Introduction

• Environmental statements should communicate accurate and relevant information about a product’s environmental aspects or potential environmental impacts.
• Assessment methods should be transparent, scientifically sound and documented. In practice, this means the evidence behind a claim should be traceable and checkable.
• Statements should help increase demand for products that place less stress on the environment. For a user, that means the statement should be meaningful in purchasing and product comparison.
• The document also links environmental statements to continual environmental improvement in products, so programmes should support progress rather than one-off marketing claims.

How the document positions the main statement types

SIST EN ISO 14020:2024/oprA1:2026 describes ISO 14020 as the common base for several statement types: self-declared environmental claims, ecolabels, EPDs and footprint communications. That matters because the same product can be communicated in different ways, but the underlying principles should stay consistent.

What it says about programmes and cooperation

The amendment says environmental statement programme operators are encouraged to cooperate and harmonize where relevant at regional, national and international levels. In practice, this is meant to improve consistency between schemes, reduce conflicting requirements and make claims easier to understand across markets.

How environmental statements can be communicated

The updated Introduction says an environmental statement can appear as a label, symbol, logo, electronic product label or machine-readable code. It can also be communicated through web-based product data or advertising. That gives organizations flexibility, but the claim still needs support wherever it appears.

What terms does SIST EN ISO 14020:2024/oprA1:2026 define?

SIST EN ISO 14020:2024/oprA1:2026 defines the terms that sit behind environmental statements. These definitions matter because they separate the different claim types and the roles of the parties involved.

• Environmental aspect - an element of a product or organization’s activities that interacts or can interact with the environment.
• Environmental statement - information about one or more environmental aspects or impacts of a product intended to inform and influence the market.
• Self-declared environmental claim - an environmental statement made outside a third-party programme by the product supplier or another party that benefits from the supply.
• Ecolabel - an environmental statement showing that a product meets the requirements of an ecolabelling programme.
• Environmental product declaration (EPD) - an environmental statement that presents product environmental data using predetermined indicators from life cycle assessment (LCA), plus additional information where relevant.
• Environmental statement programme - the rules and procedures for providing an environmental statement.
• Ecolabelling programme - a third-party, multiple-attribute environmental statement programme that assesses overall environmental preferability within a product category based on life cycle perspectives.
• Conformity assessment - confirmation, through objective evidence, that specified requirements have been met.

Who uses SIST EN ISO 14020:2024/oprA1:2026?

SIST EN ISO 14020:2024/oprA1:2026 is used by organizations that prepare, verify or manage environmental statements for products. That includes manufacturers, importers, distributors, retailers and marketers, since the responsible party can be any of them along the supply chain.

It is also relevant to third-party programme operators, ecolabelling bodies, EPD programme operators, auditors, verifiers and procurement or quality teams that need to judge whether a product claim is clear, comparable and properly supported. Buyers use it when they need to understand what a claim means before relying on it.

What changed in SIST EN ISO 14020:2024/oprA1:2026 from the previous edition?

SIST EN ISO 14020:2024/oprA1:2026 amends ISO 14020:2022 by updating the Introduction and selected definitions. The amendment states that the main changes are the revised introductory text and selected definition updates.

The definition updates cover environmental aspect, environmental statement, self-declared environmental claim, ecolabel, environmental product declaration (EPD), responsible party, environmental statement programme, ecolabelling programme, conformity assessment and environmental statement verification. The Introduction is also expanded to state the goals of environmental statements and to show where ISO 14020 sits in the ISO/TC 207/SC 3 document structure.

Which standards are used with SIST EN ISO 14020:2024/oprA1:2026?

SIST EN ISO 14020:2024/oprA1:2026 is linked to several other ISO documents that provide the detailed rules behind specific statement types and methods.

What does the SIST EN ISO 14020:2024/oprA1:2026 document contain?

SIST EN ISO 14020:2024/oprA1:2026 contains replacement text for the Introduction and revised definition entries in Clause 3. It also includes notes to entry and source notes that connect the terms to related ISO documents.

The amendment text refers to the structure of the ISO/TC 207/SC 3 documents on environmental statements and identifies how the family of standards is organized. In practical use, the document serves as the updated wording base for environmental statement schemes, claim preparation and verification work.

Environmental statements and programmes for products —
Principles and general requirements
AMENDMENT 1
Pages vi to viii, Introduction
Delete the Introduction and replace with the following text:

Introduction
0.1  This document contains principles and general requirements for environmental statements and
environmental statement programmes for products. The validity and accuracy of such statements is
essential to avoid unfair competition that can arise from vague, unreliable and deceptive environmental
statements (e.g. greenwashing). When assessment methods used by those who make environmental
statements are transparent, scientifically sound and documented, those who purchase, or will potentially
purchase, products can be assured of the validity and accuracy of the statements.
0.2  The overall goals of environmental statements are to:
a) communicate accurate and relevant information about the environmental aspects or potential
environmental impacts of products;
b) encourage the demand for and supply of products that cause less stress on the environment;
c) stimulate market-driven continual environmental improvement in products.
0.3  This document is one of the documents developed by ISO/TC 207/SC 3 that provide principles,
requirements and guidance for different types of environmental statements about products. These
documents include the following:
— ISO 14020 (this document), which provides common terms and definitions, principles and general
requirements for all environmental statements (e.g. self-declared environmental claims, ecolabels,
EPDs and footprint communications) and associated programmes that enable the communication of
environmental aspects and potential environmental impacts of products.
— ISO 14021, which provides principles, requirements, and guidance for environmental statements in the
form of self-declared environmental claims.
— ISO 14024, which provides principles, requirements, and guidance for environmental statements in the
form of ecolabels.
— ISO 14025, which provides principles, requirements, and guidance for environmental sta
