  • The climate finance innovation the Lab provides is essential because you cannot address the climate crisis unless you use every tool at your disposal. When it comes to these tools, we need to empower countries like Rwanda so they can be players and managers in the carbon market, not just providers of credits.”

    Dr. Jeanne d’Arc Mujawamariya

    Minister of the Environment

    Rwanda Ministry of Environment

  • Being able to build momentum, seek advice and have the support of the Lab was a really exciting opportunity. This has been such a helpful program, and we are excited to be taking things forward with The Fund for Nature. As Lab alumni, we are excited to continue engaging with and contributing to the community.”

    Kate Wharton

    Head of Natural Capital

    CrossBoundary LLC

  • Germany has been supporting the Lab since its beginning, and we have witnessed an impressive growing complexity of the projects the Lab moves forward. It reinforces the truly innovative nature of the Lab as it embraces the most difficult sectors where barriers for private finance are higher.”

    Vera Rodenhoff

    Deputy Director General, International Climate Protection and International Energy Transition

    German Federal Ministry of Economic Affairs and Climate Action

  • The Lab is unique in joining public and private investors with entrepreneurs advancing innovative projects in climate finance. FinDev Canada is proud to fund the Lab’s gender equality stream, as this long-standing initiative aligns with one of our key impact goals of promoting climate action.”
