Shanghai is the city with the most air conditioners in China. While it cools the indoors, it is however, continuously releasing carbon dioxide, which in turn warms the city. When we say global warming, the root of the problem actually starts from the city. NRDC seeks to raise awareness about this increasingly problematic issue.We designed a special fan. Every blade of the wooden fan takes on the structure and shape of Shanghai’s most iconic buildings. When people use this fan, they will literally feel the breeze that the city brings. This simple analogy identified with over thousands of Shanghainese. The design of the fan received rave reviews. It allowed more and more people to believe in the natural good that the habit of using a fan can bring. It also brought across the message that, if we continue this habit, it can help reduce the emission of harmful gases and will be a contributed step for our efforts against global warming.
