Published jointly with the Modern Energy Cooking Services (MECS) programme, this report is the fourth in the Financing Clean Cooking series which examines financing trends in the sector with the overall aim of unlocking more investment. Clean Cooking: Results-Based Financing as a Potential Scale-up Tool for the Sector evaluates past and ongoing Results-Based Financing (RBF) programmes in order to identify the key success factors for using RBF as a tool for scaling up modern energy cooking solutions. It also explores opportunities to maximise impact through linking energy access and clean cooking RBF programmes more closely and scaling up further investment by tapping into carbon financing.
