Special Interest Sections are Institute-wide groups that bring together members with a shared area of interest. These groups are open to all members and work towards improving environmental practice through information sharing, the development of guidance documents, seminars, workshops, and other activities.

Special Interest Sections generally focus on emerging opportunities or issues that require a dedicated focus over a period of time rather than ongoing committee business.

The Institute currently has the following Special Interest Sections:

• Climate Change
• Contaminated land (currently paused)
• Ecology
• Environmental Accounting
• Heritage
• Impact Assessment

Special Interest Sections are approved by the Board in accordance with the Institute's By-Law 15.
