ISO 14001 Guidance - 5. Checking

5.5 Internal audit

Internal audits of an environmental management system can be performed by personnel from within the organization or by external persons selected by the organization, working on its behalf. In either case, the persons conducting the audit should be competent and in a position to do so impartially and objectively. In smaller organizations, auditor independence can be demonstrated by an auditor being free from responsibility for the activity being audited.


NOTE 1 If an organization wishes to combine audits of its environmental management system with environmental compliance audits, the intent and scope of each should be clearly defined. Environmental compliance audits are not covered by this International Standard.


NOTE 2 Guidance on auditing of environmental management systems is given in ISO 19011.
