Madrid is drawing up lans to plant gardens on the rooftop of the city’s buses and bus stops.
The authorities in the Spanish capital have come up with the proposals as a novel way of tackling CO2 emissions, The Local reported. The gardens are also intended to soak up heat, noise and pollution.
A garden on a bus rooftop will cost 2,500 Euros (£2,143.35). Those on the top of bus shelters will be rather cheaper.
The project, known as “Muévete en verde” , is one of six schemes designed to improve the city’s environment. They were chosen out of 800 entries.
