With the Olympics now just a short time away, it is appropriate to examine the city's cleanup progress to date. This article does so, and also quantifies some of the health benefits of these cleanup activities, placing an economic value on the gains. Results for air pollution cleanup indicate an economic gain of nearly 50 billion yuan over a ten-year period, with a potential annual gain of 3.5 billion yuan for reaching air quality standards. Water pollution results suggest a potential annual gain of another 2.6 billion yuan.
