China, like several other countries, is exploring the creation of sustainable urban areas, or “ecocities” as they are known.
Around the world, ecocities are beginning to emerge from the drawing board, from Masdar City in Abu Dhabi to PlanIT Valley in Portugal.
Aimed at being the world’s largest of its type, Tianjin Eco-city is a collaborative project between the Chinese and Singaporean government that will house 350,000 people in a low-carbon, green environment around half the size of Manhattan by 2020.
