This type of architecture is the literal definition of green washing. It’s just a concrete tower with incredibly difficult to maintain trees. (Probably next to a 6 lane arterial road.)
Good question. Adding trees and other forms of applied solarpunk to concrete "buildings that have already been built" is different than prefabricated green skyscrapers which would surely be greenwashing. Images like the one in the article can be valuable to introduce new people to solarpunk ideas and positive visions of the future.
