ISO 14025:2006

Overview

ISO 14025:2006 - "Environmental labels and declarations - Type III environmental declarations - Principles and procedures" defines principles and procedures for developing Type III environmental declaration programmes and Type III environmental declarations (often known as Environmental Product Declarations or EPDs). The standard requires use of the ISO 14040 series (LCA principles and requirements) and sets rules for transparent, comparable, life-cycle-based environmental information primarily for business-to-business communication, with provision for business-to-consumer use under specific conditions.

Key topics and requirements

• Life cycle basis (LCA/LCI): Declarations must be based on life cycle assessment (LCA) or life cycle inventory (LCI) data in accordance with ISO 14040/14044.
• Product Category Rules (PCR): PCRs specify the parameters, data modules, and reporting rules for product categories; programmes must define procedures for PCR development and review.
• Programme operator responsibilities: Operators (companies, trade associations, public bodies or independent organizations) manage the programme, define scope, administer PCRs, and ensure harmonization and comparability.
• Transparency and modularity: Information must be transparent and may be presented as information modules covering unit processes or parts of products to support composability.
• Verification and review: Declarations require verification; independence of verifiers and competence requirements are specified. Third-party verification is particularly expected for business-to-consumer declarations.
• Comparability and harmonization: The standard encourages mutual recognition and harmonized programme instructions to enable fair comparison between products.
• Voluntary nature and legal compliance: Participation is voluntary; ISO 14025 does not replace statutory labeling or legal requirements.

Applications and who uses it

ISO 14025 is used to produce credible, comparable environmental data for products and services. Typical users include:

• Manufacturers and brand owners preparing EPDs for procurement or supply chains.
• Programme operators (industry bodies, certification bodies, NGOs) establishing Type III programmes.
• LCA practitioners and environmental consultants compiling LCAs and PCRs.
• Independent verifiers and review panels assessing declaration compliance.
• Public procurement agencies, architects, specifiers, and large buyers using EPDs to inform sustainable purchasing.
• SMEs seeking to demonstrate environmental performance in B2B markets.

Related standards

• ISO 14021 / ISO 14024 - Type II and Type I environmental claims and labelling (contextual references).

ISO 14025:2006 is essential for organizations seeking robust, LCA-based Environmental Product Declarations (EPDs), ensuring transparency, comparability and independent verification across product supply chains.
