Testing must be accurate and based on widely recognized scientific methodologies. The specific methodology depends on the type of claim to be made. For example, if I want to communicate a single characteristic—such as the percentage of recycled material in my product—I can refer to the guidelines in ISO 14021; or, if I want to make a more credible claim, I can opt for third-party certification on that topic (e.g., Plastica Seconda Vita). If I want to communicate that my product has a reduced environmental impact or is eco-friendly/green, I must provide evidence of“recognized excellence in environmental performance,”namely: compliance with Regulation (EC) No. 66/2010 of the European Parliament and of the Council (Ecolabel), a national or regional Type I eco-labeling system in accordance with EN ISO 14024, officially recognized in the Member States, or compliance with best environmental performance in accordance with other applicable provisions of Union law.
