Il New York Times (link alternativo) parla degli obiettivi di Milano su verde e sostenibilità ambientale.

The project to make Milan greener includes an ambitious plan to transform a disused freight railway network into a series of seven parks, with 25,000 new trees every year. It also includes planting greenery on 10 million square meters (108 million sq. feet) of flat rooftops and planting trees in 2,300 school courtyards.
