The Acros Fukuoka eco-building in Fukuoka, Japan boasts one of the world’s most famous green roofs. The GRIT Lab at the University of Toronto is working to bring green roofs to the city and beyond in order to combat climate change.
Green roofs could play a critical role in helping cities cope with extreme rainfall events in the age of climate change. The roofs essentially suck up stormwater like sponges if designed properly.
