• Over 4 billion people live in cities.

• Cities account for more than 80 percent of global GDP (McKinsey Global Institute 2011). 

• Cities consume more than two thirds of global energy and account for 70 percent of global emissions (World Bank 2010, p.15; UNFCCC 2017, p.8).

• Cities provide basic infrastructure and services, but often lack the fiscal resources to maintain and expand them.

• Curbing the negative impacts of climate change depends on cities providing sustainable urban infrastructure and services.
