These are Asia’s 22 greenest metropolises!



14. Nanjing

Nanjing, with a population of 7.7million, is a major manufacturing base with special focus on chemical and car production, but also a growing service economy.

Although the city boasts the largest inland port in China, it generates a GDP per capita of only $7,300 and therefore falls into the low-income range.

Nanjing ranks average overall in the index, but stands out in some aspects — especially in the water category, where it benefits from low levels of water leakage and robust policies on water quality and sustainability.
