The Climate Change Budget Integration Index (CCBII) has been developed by UNDP as a tool for measuring the level of integration of Climate Change (CC) into national Public Financial Management (PFM) systems. The assessment of the level of integration of CC in the PFM systems will bring a more systemic approach to, and objective validation of, the progress towards a CC-integrated PFM system. It can also set a baseline, help with the formulation of a prioritized reform agenda for CC integration; facilitate cross-country comparison; and build a platform for cooperation with development partners.
