DIN EN ISO 14025 (often shortened to ISO 14025) “Environmental Trademarks and Declarations – Type III Environmental Declarations – Principles and Procedures” is the basis for environmental trademarks in compliance with Type III. ISO 14025 regulates, among other things, how Type III Environmental Declarations and Type III Environmental Declaration Programmes are created and in particular, specifies the application of the DIN EN ISO 14040 series of standards for their creation. This enables comparisons between products that have the same function – on the basis of quantified environmental information from the life cycle of a product.
