Cities occupy a fraction of the Earth's surface but produce almost two-thirds of greenhouse gas emissions. A new approach to developing townships is mitigating this.

Across Asia Pacific, cities are feeling the weight of rapid urbanization. More than half of the global population currently lives in a city, with 54% of these in Asia. The region is already home to most of the world's megacities, which house more than 10 million people, and each year more are joining the list. By 2050, the urban population in Asia is expected to double, which would represent an additional 1.2 billion people migrating to the region's cities.
