This report includes of a selection of case studies that illustrate each of the ten guiding principles which are featured in the first publication of this series on International Good Practice Principles for Sustainable Infrastructure. 

Together, the publications aim to inform the forthcoming wave of global infrastructure investment. Collectively, they specify and demonstrate how environmental, social, and economic sustainability must be integrated right across infrastructure policymaking at the systems-level. The individual principles and case studies were developed via ongoing global consultation and inputs from experts and UN Member States, as part of implementation of the UN Environment Assembly (UNEA) Resolution 4/5 on Sustainable Infrastructure.
