The Mackenzie Valley Resource Management Act states that an independent audit of the environment must take place in the Mackenzie Valley at least once every five years. Similar requirements for environmental audits are described in the Sahtu, Gwich'in and Tlicho agreements.
Conducted by an independent auditor, the first-ever NWT Environmental Audit was completed in December 2005. Unique in Canada, this audit examined the overall health and future of the NWT environment by reviewing the effectiveness of programs and processes related to monitoring cumulative impacts and the effectiveness of the regulation of land and water use. The audit made recommendations for ways of improving the environment and how it is managed.
The second independent environmental audit was completed in 2010.
