Committees play a critical role in GCF governance. Since 2019, the Co-Chairs have had an outstanding mandate to consult with the Board and propose measures to enhance their efficiency. At B39, the Co-Chairs proposed to advance a phased approach for addressing related Committee issues. In line with that approach, this document reviews the findings and recommendations of the 2019 independent review of Committees, past Board concerns and proposals on Committees, and a recent benchmarking review of Committee operations in a broad group of comparators. On that basis, this document advances the CoChairs proposed priority changes to better support the Committees’ ability to meet and to enhance Committee transparency and Board input into Committee considerations. The CoChairs also propose that the Board give a continued mandate for incoming Co-Chairs to consult on measures to support continuous improvement in Committee efficiency and effectiveness, including considering issues related to Committee structure and practices.
