Stefano Boeri, the renowned Italian architect famous for his tree-clad Bosco Verticale skyscraper complex in Milan, has a new, greener vision for pollution-plagued China. His next project, in the eastern Chinese city of Nanjing, will consist of two neighbouring towers covered with 23 species of tree and more than 2500 cascading shrubs.

Currently under construction and set for completion next year, this is just the beginning of Boeri’s bold plans for China. His aim is to create ‘forest cities’ – a life-changing transformation for a country that is famous for smog and environmental destruction.

Boeri said, “We have been asked to design an entire city where you don’t only have one tall building but you have 100 or 200 buildings of different sizes, all with trees and plants on the facades. We are working very seriously on designing all the different buildings. I think they will start to build at the end of this year. By 2020 we could imagine having the first forest city in China.”

His Milan-based practice claimed the buildings would suck 25 tonnes of carbon dioxide from Nanjing’s air each year and produce about 60 kg of oxygen every day. “It is positive because the presence of such a large number of plants, trees and shrubs is contributing to the cleaning of the air, contributing to absorbing CO2 and producing oxygen. And what is so important is that this large presence of plants is an amazing contribution in terms of absorbing the dust produced by urban traffic.”

“Two towers in a huge urban environment [such as Nanjing] is so, so small a contribution – but it is an example. We hope that this model of green architecture can be repeated and copied and replicated.”
