Singapore, already one of the greenest cities in Asia, now has the distinction of having the world's tallest vertical garden - the 24-story Tree House condominium.

Asia may not have the equivalent of a completely green city such as Vancouver in Canada, which started on this path 10 years ago, but there are some cities in the region making the right moves.

The Chinese government is already moving toward building eco-cities - places where people can live healthier and economically productive lives while reducing their impact on the environment.

Steffen Lehmann, a sustainable design and behavior specialist with the University of South Australia, says that the idea behind eco-cities is to live with the environment and resources".

"Eco-cities strive to cut greenhouse gas emissions by producing energy through renewable sources such as solar, wind and biomass, and using low-carbon public transport," Lehmann says, adding that resources are conserved through waste management techniques such as natural bio-filtration of storm water.

"There are even plans to grow food and plant new green areas within the boundaries of the city," he says. "The ambitious ultimate goal of these cities is self-sufficiency."

Ramola Naik Singru, one of the region's leading urban development experts, says there is an urgent need for Asia to focus on making cities more livable and greener.
