The development of sustainable infrastructure is recognized by policy makers globally as key to realizing the Sustainable Development Goals (SDGs) and the targets of the Paris Agreement. At the same time, the public and private sector still struggle to build and operate infrastructure that meets the four dimensions of sustainability: economic and financial, environmental, social and institutional. Increasingly, this problem goes back to an information gap regarding existing sustainability solutions. To provide stakeholders with adequate information, more and more tools applicable to different infrastructure sectors and different phases along the infrastructure lifecycle have been developed to assess the sustainability of infrastructure assets. Yet, for stakeholders it remains difficult to identify the right tool. By operating the Sustainable Infrastructure Tool Navigator, GIZ’s Infrastructure Solutions Incubator and UNEP’s Sustainable Infrastructure Partnership aim to bring clarity to the infrastructure sustainability arena and thereby increase uptake of innovative infrastructure solutions that meet sustainability principles.
