France passed law making rooftop solar or gardens mandatory on new commercial buildings

Two months ago, France passed a law that requires the rooftops of new commercial buildings to be partially (at least) covered by solar panels or plants. The law, passed back in March, was a compromise with French environmentalists and more conservative* members of society.

The law approved by parliament was more limited in scope than initial calls by French environmental activists to make green roofs that cover the entire surface mandatory on all new buildings.The Socialist government convinced activists to limit the scope of the law to commercial buildings.

This isn’t a first. Places like Australia and Germany already have green roofs as a part of their urban landscape. Toronto has had by-laws since 1998 mandating green rooftops (1).
