The G20 Finance Ministers and Central Bank Governors endorsed the G20 Principles for Quality Infrastructure Investment (QII) in June 2019. The QII Principles are voluntary, non-binding principles that reflect a common strategic direction and aspiration for quality infrastructure investment. The Compendium of Quality Infrastructure Investment Indicators, developed for the G20, provides "a menu of voluntary, non binding, non prescriptive and customisable indicators" relevant to the QII Principles. This Guidance Note complements the Compendium.
