France decrees new rooftops must be covered in plants or solar panels
Rooftops on new buildings built in commercial zones in France must either be partially covered in plants or solar panels
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.
The law was also made less onerous for businesses by requiring only part of the roof to be covered with plants, and giving them the choice of installing solar panels to generate electricity instead.
