Subnational Government Climate Finance Hub



Given the urgency of the climate crisis, it is more important than ever to improve our understanding of the financial role of subnational governments in the transition, to track the progress regions and cities are making towards achieving the Paris Agreement commitments and other green objectives, and to identify areas where further action is needed to align their expenditure, investment and revenues with their climate goals and mobilise additional sources of finance.
