Types and Costs of Environmental Audits
We have already encountered environmental audit as part of an Environmental management system. We saw how the audit is used to assess how well the EMS is conforming to the programme and how effective the EMS is in fulfilling the organization’s environmental policy.
In order for an organization to effectively manage or control it’s environment, it has to be able to assess whether the systems already in place are effective.
In order to do this, the aim is to compare the prevailing conditions with baseline conditions or with set criteria. As we have already seen audits can be internal, external or third party audits. Environmental audits were adapted from Accounting Audits and usually lead to the identification of risks or of cost saving activities.
Environmental Audit has been defined by the International Chamber of Commerce as A management tool comprising a systematic documented and periodic and objective evaluation of how well environmental organization, management and equipment are performing with aim of helping to safeguard the environment by:
Facilitating management control of environment practices
Assessing compliance with company policies, which would include meeting regulatory requirements
This definition means that audits can be used to
Verify compliance with environmental requirements
Evaluate the effectiveness of EMSs already in place
Assess risk from regulated or unregulated materials and practices
EMS management standards such as the ISO have definitions which refer specifically to the EMS thus the Environmental audit has been defined by ISO as a systematic, independent and documented process for obtaining audit evidence and evaluating its objectivity to determine the extent to which the EMS audit criteria set up by the organization are fulfilled.
Environmental auditing involves a series of activities set up by management to evaluate the environmental performance of organizations. Legislative compliance checks as well as an assessment of all aspects of the organization that may impact the environment are carried out.
Environmental audit is a vital management tool that works as part of a process of continuous improvement. Audit was first used in the context of the environment in the U.S.A and developed from the audit procedure used for financial reporting.
