ISO 14021:2026

Overview

ISO 14021:2026 is the internationally recognized standard for self-declared environmental claims about products. Developed by the International Organization for Standardization (ISO), this document provides essential principles, requirements, and guidance for organizations making claims about the environmental aspects of their products. The scope of the standard covers verbal, symbolic, and graphic claims, whether made on packaging, in product literature, on advertising materials, or through digital channels.

The standard helps businesses communicate accurate, transparent, and verifiable information about the environmental performance of their products. It aims to harmonize the language and methodology for self-declared environmental claims, reduce the risk of greenwashing, and promote global consistency in environmental communications.

Key Topics

• Principles for Environmental Claims
  ISO 14021 sets out guiding principles to ensure claims are meaningful, substantiated, and not misleading. Clarity, accuracy, and relevance are core requirements.

• Terminology and Definitions
  The standard defines key terms commonly used in environmental communications, providing consistency across industries and markets.

• Documentation and Methodology
  Organizations must document methodologies and data used to support claims, ensuring transparency and traceability for verification.

• Claim Qualification
  The standard outlines qualifications and limitations on the use of common claims (e.g., “recyclable,” “biodegradable,” “compostable”) and requires the use of supporting information or explanatory text as appropriate.

• Programme Requirements
  Self-declared environmental claims must be managed within an organized programme, which includes programme operators, defined processes, and requirements for stakeholder engagement, scope, and intended audiences.

• Use of Symbols and Graphics
  Guidance is provided on the appropriate use and limitations of environmental symbols on products, such as the Mobius loop, to avoid consumer confusion.

• Social and Economic Considerations
  The document considers related social and economic impacts connected to a product’s environmental performance, supporting holistic sustainability communication.

Applications

ISO 14021:2026 is widely applicable across industries and sectors for organizations seeking to communicate environmental attributes of their products. Key practical applications include:
