In a new law passed in March this year, the French are set to join Germany and Australia in yet another environmental advancement: green rooftops.
Passed by French government officials, the law rules that buildings in commercial zones of France must either be partially covered in plants or solar panels. The law has less scope than the original plan put forward by environmental activists to completely cover rooftops, and was made less onerous for businesses by ruling that only part of the roof be covered in greenery, and giving people the choice of installing solar panels to generate electricity instead.
The green rooftops have an isolating effect, meaning that they help reduce the amount of energy needed to heat a house in the winter and keep it cool in the summer. The panels and greenery also retains rainwater, and - according to ecologists - aids biodiversity, as well as giving birds a place to nest.
