What is ISO 14040 / 14044?

What is ISO 14040 / 14044?

ISO 14040 is the international standard that sets out the principles and framework for life cycle assessment. Published by the International Organization for Standardization, it defines the four phases of an LCA, the core concepts, and the methodological principles every credible assessment must follow. It works hand in hand with ISO 14044, which provides the detailed requirements and guidelines. Together they form the foundation for virtually all standardised LCA work.

Why ISO 14040 matters

ISO 14040 matters because it is the difference between an environmental claim and a credible one. Without a common framework, anyone could call any calculation an "LCA." ISO 14040 establishes the principles, including a life cycle perspective, an environmental focus, scientific rigour, and transparency, that a study must respect to be taken seriously by regulators, customers, and reviewers.

It is also the reference point that downstream methods build on. EF 3.1, ISO 14067 for carbon footprints, and EPD programme rules all assume an ISO 14040/14044 foundation. Compliance with the regulation usually starts here.

What ISO 14040 defines

ISO 14040 establishes the four-phase structure of an LCA, covering goal and scope definition, life cycle inventory, life cycle impact assessment, and interpretation, and the principles that govern them: a life cycle perspective spanning cradle to grave, a focus on environmental aspects, methodological transparency, scientific soundness, and the priority of clear, honest reporting. It sets the conceptual framework; ISO 14044 then specifies how to meet the requirements in practice.

ISO 14040 versus ISO 14044 and ISO 14067

These standards are easy to confuse. ISO 14040 provides the principles and framework, the "what and why." ISO 14044 provides the requirements and detailed guidance, the "how." ISO 14067 is a separate standard specific to the carbon footprint of products, building on the 14040/14044 framework but narrowing the focus to greenhouse gas emissions. A full multi-impact LCA cites 14040/14044; a product carbon footprint typically cites 14067 as well.

ISO 14040 and regulatory compliance

When a regulation or an OEM asks for a "compliant" LCA, ISO 14040/14044 is almost always the baseline being referenced. An EU Battery Regulation carbon footprint, an EPD, or a CBAM emissions figure all expect an assessment built on these principles, often with an independent critical review to confirm conformance. Citing the standard is not a formality. It signals that the study followed a recognised, defensible method.
