Sustainable Cities

As the world increasingly urbanizes, cities must be at the forefront of global efforts to reduce greenhouse gas emissions and climate change risks. Cities not only account for 70% of global CO2 emissions from energy use, they are also at the forefront of climate change vulnerability, with a majority already experiencing harmful impacts to their citizens and infrastructure as a result of extreme weather events. To address this, trillions of dollars in finance for climate action in cities is needed – highlighting a significant investment gap in urban climate solutions.

CPI is Secretariat for the Cities Climate Finance Leadership Alliance (CCFLA), the only multi- level and multi-stakeholder coalition aimed at closing the investment gap for urban subnational climate projects and infrastructure worldwide. CCFLA provides a platform to convene and exchange knowledge among all relevant actors dedicated to urban climate action. It also publishes research encompassing key topics including the state of cities climate finance, scaling finance for zero carbon buildings, and urban adaptation finance.
