Including these sustainability expectations in contractor requirements can help the entity effectively implement its policies for sustainable development projects, particularly when they become enforceable through written contractual agreements.

Input: How do I complete this indicator?

Select yes or no. If yes, select all applicable sub-options.

Percentage of all projects: Provide the percentage of all projects covered. The numerator is the floor area of the projects for which the applicable requirements are in place. The denominator is the total floor area of all projects reported in DR1.
