By 2050, two-thirds of the world’s population will live in cities. Urbanization is happening faster than at any time in human history.

Globally, 900 million people are living in slums. Cities can’t add housing fast enough. Today, an estimated one billion vehicles are already bringing urban areas to a standstill. Cities consume three-quarters of the world’s energy each year and are responsible for around 50% of greenhouse gas emissions. 

These are challenges our cities have been facing for decades.   

But now some city leaders, businesses, and even citizens are taking new approaches to tackle these old problems. They’re transforming their cities with technology.
