With 'City Oases' you can now discover the cool sides of Vienna. 'City Oases' was developed by the environmental protection organization Global 2000 together with the International Institute for Applied Systems Analysis (IIASA) and the Federal Environment Agency. "What you can see at a glance is that especially the places that have greenery are cool. Of course, places that combine greenery and water are particularly attractive," Martin Wildenberg of Global 2000 told Radio Wien. "City Oases" is available for both Android and Apple devices.
