Sustainability rating schemes

Waka Kotahi is committed to delivering positive environmental, social and cultural outcomes as part of the planning, design, construction and operation of our infrastructure projects. To help achieve these outcomes Waka Kotahi adopted the Infrastructure Sustainability Council sustainability rating scheme to drive, measure and recognise sustainability performance and outcomes on our high-value projects.
