4.1.1.5. Application of Article 12 of the UCPD to environmental claims

Article 12 of the UCPD clarifies that any claim (including environmental claims) should be based on evidence which can be verified by the relevant competent authorities. Traders must be able to substantiate environmental claims with appropriate evidence. Consequently, claims should be based on robust, independent, verifiable and generally recognised evidence which takes into account updated scientific findings and methods. There is no equivalent obligation in the UCPD for the trader to provide documentation or other supporting evidence to consumers. The burden of proof regarding the accuracy of the claim rests on the trader. Article 12(a) of the UCPD provides that enforcement authorities should have the power ‘to require the trader to furnish evidence as to the accuracy of factual claims in relation to a commercial practice’. The application of this requirement must take into account the legitimate interests of the trader, such as in the case of trade secrets or the protection of intellectual property, which authorities may have to treat confidentially. In order to ensure that environmental claims are substantiated, traders should either have the evidence necessary to support their claims from the time the claims are put into use or be certain that it can be obtained and presented upon request. Although a claim may be correct and relevant to a product when the claim is first made, it could become less meaningful with time. In order to ensure that they are in a position to provide necessary documentation to national authorities in line with Article 12 of the Directive, traders should make sure that documentation for claims is up to date for as long as the claims remain in use in marketing. The presented evidence should be clear and robust. Independent third party testing should be made available for the competent bodies if the claim is challenged. If expert studies give rise to significant disagreement or doubt over environmental impacts, the trader should refrain from the claim altogether. The content and scope of the documentation to be supplied will depend on the specific content of the statement. The complexity of the product or activity will be of relevance in this respect.
