Despite recognition of its importance, reliable methods for mechanisms for ensuring that climate and development finance reaches women and marginalized groups are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
