Vertical gardens absorb gaseous pollutants and carbon-dioxide and breathe out oxygen, leading to reduced air-conditioning requirements and carbon emissions. They insulate buildings against noise and outside temperature changes, extending the building envelope life and provide protected spaces for birds, bees and butterflies, contributing to biological diversity. They directly reduce the Urban Heat Island Effect, a phenomenon caused by the centralised heat produced by our cities. The installation of Vertical Landscapes can earn property developers green building credits.
