Challenge: In recent years, China has been plagued by smog and the PM2.5 is highly stubborn. However, since many people have become accustomed to this kind of environment, they do not take any protection measures, which is currently a major social problem.
Solution: Beijing Dentsu CDC China and Kobayashi Pharmaceutical Company jointly developed the "Air Pollution Discount" website, which is linked to China's domestic air quality index (AQI) in real time. According to the location information indicated by the GPS on a smartphone, it accesses the region's real-time PM2.5 data. The more serious the air pollution is in the area, the greater the discount will be, so that everyone can buy Kobayashi's masks at lower prices. While enjoying the benefits, it increases the likelihood of people paying attention to and using air pollution prevention measures.
