Now, in Tokyo, the so-called “2003 problem” has become the big center of attention. It came to the urban redevelopment last in the Yamanote Line inner side which became the forerunner of the “2003 Problem” of the 20th century, and the environmental load by which the major urban redevelopment in the Tokyo newly emerging city center brings Yebisu Garden Place in an area to an example by thispaper, and quantitive consideration was tried in it. For the environmental load which a major urban redevelopment brings about, various things, such as air pollution, noise, vibration, water pollution, greenhouse gas, a wind damage, sunshine prevention and so on can be considered. This paper considered environmental load by making air pollution (nitrogen dioxide, nitrogen oxide) into a representation index. Consequently, it is before and after enforcement of a redevelopment project, and it turns out that automobile traffic increases twice and the environmental load of the air pollution resulting from an automobile exhaust gas increases 1.8 times. Furthermore, it also turns out the influence area of high concentration air pollution, and that it increases centering on a place along the route more sharply than development before.
