The Ideas

The ideas featured on this page have been shortlisted as the most promising transformative green finance instruments from hundreds of submissions via an open call for ideas. At the beginning of each Lab cycle, Lab Members vote on the top several shortlisted ideas to move into development, benefiting from guidance from Lab Members and expert working groups, as well as from in-depth analysis provided by the Lab Secretariat. Depending on their development, at the end of each cycle, several instruments are endorsed by the Lab for launch and piloting. For more details about the Lab’s approach, visit how it works.
