According to Clause 3.2: Clarification of structure & terminology

The clause structure and some of the terminology of ISO 14001 have been changed to improve alignment with other management systems standards.

There is, however, no requirement in ISO 14001:2015 for its clause structure or terminology to be applied to an organization’s environmental management system documentation.

There is no requirement to replace the terms used by an organization with the terms used in ISO 14001:2015.
Organizations can choose to use terms that suit their business, e.g. “records”, “documentation” or “protocols”, rather than “documented information”.

According to Clause 3.3: Clarification of concepts

In addition to the terms and definitions given in Clause 3 of ISO 14001:2015, clarification of selected concepts is provided below to prevent misunderstanding:

  • In ISO 14001:2015, the use of the word “any” implies selection or choice.
  • The words “appropriate” and “applicable” are not interchangeable.
    “Appropriate” means suitable (for, to) and implies some degree of freedom, while “applicable” means relevant or possible to apply and implies that if it can be done, it needs to be done.
  • The word “consider” means it is necessary to think about the topic but it can be excluded; whereas “take into account” means it is necessary to think about the topic but it cannot be excluded.
  • “Continual” indicates duration that occurs over a period of time, but with intervals of interruption (unlike “continuous” which indicates duration without interruption). “Continual” is therefore the appropriate word to use when referring to improvement.
  • The word “effect” is used to describe the result of a change to the organization. The phrase “environmental impact” refers specifically to the result of a change to the environment.
  • The word “ensure” means the responsibility can be delegated, but not the accountability.
  • This International Standard uses the term “interested party”: the term “stakeholder” is a synonym as it represents the same concept.

ISO 14001:2015 uses some new terminology. A brief explanation is given below to aid both new users and those who have used previous editions of ISO 14001.

  • The phrase “compliance obligations” replaces the phrase “legal requirements and other requirements to which the organization subscribes” used in ISO 14001:2004. The intent of this new phrase does not differ from that of ISO 14001:2004.
  • “Documented information” replaces the nouns “documentation”, “documents” and “records” used in ISO 14001:1996/2004.
  1. To distinguish the intent of the generic term “documented information”, ISO 14001:2015 now uses the phrase “retain documented information as evidence of….” to mean records, and
  2. “Maintain documented information” to mean documentation other than records.
  3. The phrase “as evidence of….” is not a requirement to meet legal evidentiary requirements; its intent is only to indicate objective evidence needs to be retained.
  • The phrase “external provider” means an external supplier organization (including a contractor) that provides a product or a service.
  • The change from “identify” to “determine” is intended to harmonize with the standardized management system terminology.
  • The word “determine” implies a discovery process that results in knowledge. The intent does not differ from that of previous editions.
  1. The minimal intended outcomes include enhancement of environmental performance, fulfilment of compliance obligations and achievement of environmental objectives.
  2. Organizations can set additional intended outcomes for their environmental management system. For example, consistent with their commitment to protection of the environment, an organization may establish an intended outcome to work towards sustainable development.
  • The phrase “person(s) doing work under its control” includes persons working for the organization and those working on its behalf for which the organization has responsibility (e.g. contractors).
  1. It replaces the phrase “persons working for it or on its behalf” and “persons working for or on behalf of the organization” used in ISO 14001:2004.
  2. The intent of this new phrase does not differ from that of the previous edition.
  • The concept of “target” used in ISO 14001:2004 is captured within the term “environmental objective”.
