These are Asia’s 22 greenest metropolises!



22. Karachi

Karachi, Pakistan’s largest city and commercial capital, generates a GDP per capita of $5,400. With an urban population of about 14.5 million, it is one of the world’s fastest-growing metropolises.

In the index, it ranks well below average overall. Its best performance is in the water category, mainly for a low rate of per capita water consumption.

Karachi has its biggest challenges in the transport and air quality categories. There are several projects underway to improve transport, sanitation, water and waste infrastructure.
