Vertical Forests

Nanjing Vertical Forest, which is scheduled to be fully built by 2018, and will bring thousands of trees and shrubs into the highly populated Pukou District of the city, absorbing tons of CO2 and producing a wealth of oxygen at the same time.

The structure will have 1,100 large and medium-sized trees on its facades, along with 2,500 other plants and shrubs. The plants are expected to provide 60kg of oxygen per day while absorbing over 25 tons of carbon dioxide every year.

The architect M. Boeri has also designed and built similar forests in Milan, a pair of adjacent towers.

The New York Times reports that construction began in 2009 and was completed in 2014. The Nanjing project is much larger in scale and ambition, more than doubling the number of plants as well as increasing the total height of the towers themselves.

The Guardian‘s artist has a bigger fantasy:
