Shanghai gets it! In an article in China Daily, it was reported that "The Shanghai landscaping administration bureau said more than 95,000 sq m of rooftops have been covered in grass and shrubs, very close to the annual target of 100,000 sq m. The city's annual construction of green areas will be about 200,000 sq m this year, the bureau said."
This is fantastic news. Shanghai's air pollution is the third worst in China, only behind Guanzhou and Beijing. The overall commitment to improve the cityscape with green roofs is real, although annual budgets aren't very high. From the article, "The city will spend 5 million yuan ($710,000) this year on the campaign."
Like other government sponsored green roof projects, like those of Chicago, the focus is primarily on government buildings. What is positive to note is scale and commitment of putting green roofs in Shanghai. Again, from the article, "Since the campaign began in 2003, at total 500,000 sq m of Shanghai's rooftops have been covered, more than 80 times the size of Fuxing Park, a popular recreational area in downtown Shanghai."
Let's hope that with the rapid construction in Shanghai, builders and government can work together to get green roofs on as many buildings as possible.
