ISO 14001 Internal Audit — Clause 9.2 for Environmental Management
Just like its quality sibling, ISO 14001 requires internal audits at planned intervals under Clause 9.2. For an EMS the audit lens is different: it centers on significant environmental aspects (Clause 6.1.2) and compliance with legal and other requirements (Clause 9.1.2).
Clause 9.2 in the EMS context
Clause 9.2 mirrors the quality requirement: planned internal audits that confirm the EMS conforms to the organization’s own requirements and to ISO 14001. The audit scope, however, must be driven by the significant environmental aspects, the compliance obligations, and the results of previous audits.
Auditing aspects and compliance
A strong EMS audit checks whether the controls for each significant aspect (Clause 6.1.2) are operating, and whether the organization can demonstrate compliance with legal and other requirements (Clause 9.1.2) through permits, monitoring and calibration of emissions equipment. This is where EMS audits differ most from generic QMS audits.
Typical EMS findings
Common gaps: an aspects register that hasn’t been updated after a process change; missing evidence of permit compliance; and corrective actions (Clause 10.2) that don’t trace back to the aspect they were meant to control.
Frequently asked questions
Does the same auditor model apply as ISO 9001?
Yes — Clause 9.2 requires objective, impartial auditors who don’t audit their own work. The subject matter differs (environmental aspects and compliance rather than product conformity).
How do environmental aspects drive the audit plan?
Your significant aspects register and compliance obligations are the risk basis for the audit program. Higher-risk aspects and sites with poor compliance history get audited more frequently.
Are ISO 14001 and ISO 9001 audits usually combined?
Increasingly yes. Because both use Annex SL, many organizations run integrated audits covering Clauses 4–10 for both standards, which auditors accept when the auditor is competent in both.
