Environmental Auditing

Environmental auditing is a sub-theme of environmental management.

Implementing and maintaining an environmental management system (EMS) has been shown to bring huge benefits to companies (cost savings, greater resource efficiency, reputation, etc.). Environmental auditing is necessary to ensure an EMS is correctly applied to support individual business needs. It provides assurance of an organization's capability, helping with its legal compliance and better equipping it to deal with incidents.

The number of reports published continues to increase and many national governments have introduced some form of mandatory reporting requirements.



Standards on environmental auditing verify whether objectives and targets are being met, whether part of environmental performance evaluation or an EMS.

Just as with environmental performance evaluation, environmental auditing helps with:

  • Price/ cost management
  • Compliance
  • Competitive advantage
  • Brand/ reputation
  • Attracting investment
  • Mitigation of environmental issues
  • 'Due diligence'
  • Competency assessment

Audits deliver consistency and robustness of claims that regulators can rely on.
