Drawing from a number of existing or proposed RBF programmes relevant to climate change, these triggers can include the number of natural gas connections made or solar-home systems installed (GPOBA, 2013), the number of technical assistance sessions held (IFC, 2012a), or the amount of fugitive methane emissions abated (MFSG, 2013). The first relates to the requirement of demonstrating verified results up-front. With an ex-ante assessment of mutually agreed outputs or outcomes, donors can more easily account for results to both taxpayers at home and development partners abroad. The second is how RBF approaches transfer risk from donors to service providers, thus creating a direct incentive to achieve the result more efficiently and effectively (World Bank, 2013a).
