Agencies will need to document if the project or program is sustainable. Agencies must demonstrate they have scoped and evaluated the social, economic and environmental impacts (negative and positive) that are a result of the options.

Agencies need to address the following areas only if applicable, and if they have not already been included in other areas of analysis such as 4.3 Costs and Benefits.
