Stefano Boeri’s ‘Vertical Forest’ consists of two high-rise apartment blocks whose many reinforced balconies overflow with around 700 trees and 20,000 shrubs and plants. The award-winning, sustainable design not only absorbs huge amounts of CO₂ and emits oxygen, but it also helps to mitigate pollution and moderate internal temperatures and noise. The project was so successful that Boeri is now designing a forest city in Liuzhou, China.
