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.
This report sets out several of the recent advances, and suggests the most promising approaches, to the quantification and valuation of some of the wider economic benefits that flow from transport-related development.
