Overview
EN ISO 14021:2026, titled Environmental statements and programmes for products - Self-declared environmental claims (ISO 14021:2026), is an international standard developed by CEN and ISO. This standard establishes clear principles, requirements, and guidance for self-declared environmental claims-frequently referred to as Type II environmental labels-regarding products. EN ISO 14021:2026 addresses claims made by manufacturers, importers, distributors, retailers, and other entities, ensuring these environmental communications are accurate, relevant, and verifiable.
Self-declared claims can appear as text, symbols, or graphics on product packaging, in marketing literature, technical documents, advertising, and digital platforms. The main focus of this standard is to prevent misleading statements (greenwashing), increase consumer confidence, and foster sustainable product choices.
