Urban areas produced an estimated 34 percent of global final energy demand. Projections indicate they will account for 80 percent of global energy demand in the future. Cities generate roughly 80 percent of global GDP on just 3 percent of ice free land while shortfalls persist in sanitation and housing access.

- Urban areas contribute about 80% of global GDP according to World Bank estimates
- The OECD estimates that 40% of global economic output is produced in metropolitan areas with more than 1 million people
- In 2019, the global market for smart city solutions was estimated at $410.2 billion and projected to reach $1 trillion by 2030 (IoT/ICT research)
- In 2023, global fixed broadband subscriptions reached about 1.3 billion (ITU data)
- In 2022, the IEA estimated that electrification of transport is key for urban emissions reductions; EV sales reached about 10 million in 2022 (IEA)
