Cities face critical issues like public safety, urbanisation, ageing, and more. We look at six of the world’s great cities. What are the issues they face—and how are they using smart technologies and human innovation to overcome them?

California

California has a traffic problem. Commuters in Los Angeles spend an average of 119 hours a year stuck in traffic.

Copenhagen

Although Copenhagen is known as a city of cyclists, car usage is on the rise. Car traffic shot up by 25% between 2010 and 2016.

New Delhi

New Delhi is set to become the world's most populated city by 2028. However, overcrowding is just one of its many challenges.

Kuala Lumpur

Malaysia has relatively high per-capita CO2 emissions compared to other ASEAN countries. Malaysians even produce more CO2 per capita, than China.

Guangzhou

Chinese cities are filled with skyscrapers. However, in Guangzhou, about 50,000 buildings have one basic problem: They do not have elevators.

Tokyo

With 37 million inhabitants, Tokyo is currently the largest city in the world. However, urban migration has also meant a rapidly shrinking rural population.
