While global financial capital is abundant, it flows into corporate investments and real estate rather than climate change actions in cities. Political will and public pressure are crucial to redirecting funds. Studies of economic impacts underestimate the costs of climate disasters, especially in cities, so they undermine political commitments while understating potential climate-related returns. The shift of corporate approaches towards incorporating environmental, social, and governance (ESG) impacts offers promise for private-sector climate investments but are recently contested. Institutional barriers remain at all levels, particularly in African cities. Since the Global North controls the world's financial markets, new means of increasing funding for the Global South are needed, especially for adaptation. Innovative financial instruments and targeted use of environmental insurance tools can upgrade underdeveloped markets and align urban climate finance with ESG frameworks. These approaches, however, require climate impact data collection, programs to improve cities' and countries' creditworthiness, and trainings.
