Audits and Auditors

As the Green Tier program requires participants to both develop and audit an Environmental Management System, this information is provided to give participants and auditors a full understanding about the Green Tier audit process.

When do audits occur?

Who performs the audit?

Green Tier law requires that a DNR approved outside environmental auditor must perform all external or outside audits.

Our goal is simple -- to ensure that Green Tier auditors are a strong resource for you! We are working hard to keep our approved auditors proactively engaging with the Green Tier program and together we are making program improvements.

Approved Auditors

How to become a DNR approved outside environmental auditor

Green Tier law notes approved environmental auditors must be either accredited by an International Organization for Standardization (ISO) accreditation body or meet criteria concerning education, training, experience, and performance that the department determines are equivalent to the criteria of the ISO standard.

Guidelines for becoming a DNR-approved outside environmental auditor are available.

Exemplar Global Certification

The department has chosen Exemplar Global’s EMS Auditor certification as the primary standard for Green Tier approved auditors. Exemplar Global’s program ensures that auditors meet or exceed the qualification guidelines for management systems described in ISO 14001:2015 and ISO 19011:2018.

Requirements for Exemplar Global Certified Auditors

If an auditor is Exemplar Global certified as a Management Systems Auditor, Lead Auditor or Master Auditor with either an Environmental Management Audit or ISO 14001:2015 audit scope, the DNR will recognize they have met the requirements of an outside environmental auditor under Green Tier law.

To apply to be an approved Green Tier auditor, the auditor should supply:

  • A resume
  • An audit log from the most recent year
  • copy of their certification from Exemplar Global

All applicants must successfully complete the Green Tier Auditor E-Learning Training course for final approval by the Department.

Requirements for non-Exemplar Global Certified Auditors

  • A certificate of successful completion of a certified environmental auditor course
  • Work experience in a technical or managerial role with direct environmental management responsibilities in two of the last four years
  • At least 20 audit days of environmental management system audit experience

All applicants must successfully complete the Green Tier Auditor E-Learning Training course for final approval by the Department.
