Buildings, from construction to operation, generate about 40 percent of annual global CO2 emissions. Architects worldwide are offering their solutions to transform these structures into sustainable, self-sufficient systems that can even help slow down global warming. From a vertical garden in Singapore or a bamboo arch in Indonesia to a 3D-printed house in Italy or giant timber “mushrooms” in Spain, here are carbon-neutral structures and prototypes with great design—visually and environmentally.
