This document establishes principles, specifies requirements and gives guidance on self-declared environmental claims about products and their environmental statement programmes, including claims that also cover related social and economic aspects that are affected by environmental conditions or the environmental performance of a product.

This document defines selected terms commonly used in self-declared environmental claims and provides qualifications for their use, as well as describing the documentation and methodologies required for assessing self-declared environmental claims.

This document is applicable to self-declared environmental claims that predominantly take the form of words, but can also be symbols or graphics on product or package labels, or appear in product literature, technical bulletins, advertising and publicity, including on digital platforms.

This third edition cancels and replaces the second edition (ISO 14021:2016), which has been technically revised. It also incorporates the Amendment ISO 14021:2016/Amd 1:2021.

The main changes are as follows:

- elements that are common to all the documents on environmental statements developed by ISO/TC 207/SC 3 have been removed and are now in ISO 14020:2022;
- the document has been restructured to correspond with the structure of ISO 14020;
- self-declared environmental claims are now required to be part of a documented “programme”;
- enhanced requirements have been included for documentary information to be retained to demonstrate the validity/veracity of the self-declared environmental claim; 
- new requirements have been added to disclose the effect of attribution of characteristics where it impacts the reliability of some self-declared environmental claims; 
- guidance has been added about the role that maintaining a chain of custody plays in assessing certain self-declared environmental claims, such as recycled content; 
- the specific claims included in Clause 8 have been updated to reflect changes in the market and additional claims have been added to Clause 8; 
- guidance for use of the Mobius loop symbol has been changed to address current marketplace confusion;
- identification of environmental statements that are not appropriate for self-declared environmental claims and listing of other standards that can be used for these claims has been added; 
- reference documents have been updated and some terminology has been updated to reflect general usage.
