France Declares All New Rooftops Must Be Topped With Plants Or Solar Panels

French environmentalists cheered as France passed a law mandating all new buildings being built in commercial zones must be partially covered in either plants or solar panels. This law will stimulate the trend of "green roofs" that provide multiple benefits for both the building they are stationed on and for the environment. These roofs help regulate temperatures on the building and lowers heating/cooling costs. They also capture and retain runoff water while providing a place for birds to live in an urban landscape. How can laws like this be implemented in other places like North America?
