A Massive Plan to "Decarbonize" Chicago

The architecture firm Adrian Smith + Gordon Gill are working on a massive plan to "decarbonize" Chicago's Loop. The project incorporates a halt in new building; a retrofit of half of the area's existing structures; an effort to bring residences into old office buildings; and plans for better transportation, water management, and waste collection.
