The “Sustainable Infrastructure Tool” term used by the Navigator is based on a broad understanding of instruments that support the integration of sustainability considerations into infrastructure planning and delivery. They can include both quantitative and qualitative instruments that are applied during the different phases of the infrastructure lifecycle and across all infrastructure sectors. Accordingly, “Sustainable Infrastructure Tools” are, on the one hand, Rating Systems, Benchmarks, Modelling Tools, among other, that are directly applicable to and assess the sustainability of infrastructure projects in a quantitative or qualitative manner. On the other hand, the definition also encompasses Principles, Guidelines and Standards that provide an overview of sustainability criteria for infrastructure planning and development more broadly.
