ISO 14021:2016 specifies requirements and guidance for self-declared environmental claims (Type II eco-labels) including: 'recycled content' (must state percentage and pre/post-consumer split), 'recyclable', 'refurbished', 'remanufactured', 'reclaimed', 'reduced energy/water consumption', and 'extended life product.' Claims must be accurate, verifiable, relevant, and not misleading. Adopted by reference in EU, UK, Australian, and Canadian environmental claims enforcement frameworks.

Type III declarations from Life Cycle Assessment data under ISO 14025 / EN 15804.

ISO 14040:2006 describes the principles and framework for life cycle assessment (LCA): definition of the goal and scope, the life cycle inventory analysis (LCI) phase, the life cycle impact assessment (LCIA) phase, the life cycle interpretation phase, reporting and critical review, limitations, the relationship between the LCA phases, and conditions for use of value choices and optional elements. It covers LCA and LCI studies. It does NOT describe the LCA technique in detail and does NOT specify methodologies for the individual phases — a study claiming a method on 14040's authority is claiming something 14040 declines to give. Edition 2, published 2006-07, 20 pages, ISO/TC 207/SC 5, ICS 13.020.10 / 13.020.60. Stage 90.93 — confirmed on review in 2022, so this version remains current. One amendment: ISO 14040:2006/Amd 1:2020.

ISO 14044:2006 specifies requirements and provides guidelines for life cycle assessment: definition of goal and scope, the life cycle inventory analysis (LCI) phase, the life cycle impact assessment (LCIA) phase, the life cycle interpretation phase, reporting and critical review, limitations, the relationship between the LCA phases, and conditions for use of value choices and optional elements. It covers LCA and LCI studies. This is the requirements half of the pair — 14040 states the framework, 14044 states what a study must actually do to conform. Edition 1, published 2006-07, 46 pages, ISO/TC 207/SC 5, ICS 13.020.10 / 13.020.60. Stage 90.93 — confirmed on review in 2022, so this version remains current. Two amendments: Amd 1:2017 and Amd 2:2020.

ISO 14067:2018 specifies principles, requirements and guidelines for quantifying and reporting the carbon footprint of a product (CFP), consistent with ISO 14040 and ISO 14044. Requirements for a PARTIAL CFP are also specified. It addresses only a single impact category: climate change. Carbon offsetting and the communication of CFP information are explicitly OUTSIDE its scope — a standard that quantifies a number is not a standard that licenses a label built on it. It assesses no social or economic aspect and no other environmental impact. Edition 1, published 2018-08, 46 pages, ISO/TC 207/SC 7, ICS 13.020.40. Supersedes the withdrawn ISO/TS 14067:2013.
