Associate Environmental Auditor

Registered Associate Environmental Auditors are typically active 'trainee' environmental auditors who are expected to have, as a minimum, a basic knowledge of environmental auditing.

Registered Environmental Auditor

Registered Environmental Auditors are expected to have a good appreciation of a range of environmental issues and environmental auditing techniques and to be competent environmental auditors in the areas in which they operate. However, their experience may be confined to a limited number of environmental audit types and sectors. Registered Environmental Auditors will typically be regular and active members of environmental audit teams.

Principal Environmental Auditor

Registered Principal Environmental Auditors are expected to have a wealth of environmental auditing expertise and will typically lead/manage environmental audit teams and liaise with senior management on a regular basis. They are expected to be able to take considerably greater responsibilities than registered Environmental Auditors and to have an excellent appreciation of the wide range of issues pertaining to environmental auditing.

EMS Auditor

EMS Auditors are expected to have a good appreciation of the EMS audit process and be qualified to be a member of an audit team to undertake specific duties that they have expertise in.

Lead EMS Auditor

Lead EMS Auditors are expected to have a thorough appreciation of all aspects of the EMS audit process and be qualified to lead an audit team.
