Dubai aims for superlatives: it's now racing to become one of the planet’s most sustainable cities. The emirate will showcase its efforts as host of Expo 2020, also known as the world’s fair, a six-month exhibition with sustainability as one of its themes. A decade ago Dubai had one of the largest ecological footprints of any city in the world. By 2050 it wants to have the smallest. Can it get there? My work revolves around the making of the future, how our society transitions through new ways of living, and how technology is changing our approach to the environment and to our cities.
