Quality Infrastructure Investment Database

The Quality Infrastructure Investment Database is an initiative of the G20 under the 2019 Japanese Presidency, in collaboration with the Global Infrastructure Hub, the OECD and the World Bank.

The database includes resources and facilities relevant to Quality Infrastructure Investment under the principles of Sustainable Growth & Development, Economic Efficiency, Environmental Considerations, Building Resilience, Social Considerations, and Infrastructure Governance.

In 2021, the Global Infrastructure Hub published the findings of a survey of G20 members that collected case studies and examples of projects or programs that demonstrate the benefits of QII or exemplify good practice in their countries or in recipient countries. This survey was undertaken at the request of the G20 Infrastructure Working Group (IWG). It can be accessed here.
