The Beijing Environmental Protection Bureau may try to go the last-resort avenue to reduce air pollution for the Olympics. On high pollution days and depending on the weather, some cars would be banned from operation. (SCMP 4/27). This is, of course, all being planned in conjunction with traditional environmental regulatory measures, such as emissions controls. Cars kept off the road would be higher emission vehicles, most likely older vehicles.
Also, pollution levels in the Three Gorges reservoir, created by the Three Gorges Dam, is likely to become a significant public health and environmental problem. While pollution control have been stepped up, Professor Shu at a research institute of a PLA's Medical Hospital has said that only 20% of polluted water inflows are treatd. Shu just received an environmental protection award from the central government on Three Gorges reservoir water quality issues. (SCMP 4/27).
