Air pollution can be an unfavorable product raised by modern industrial civilization. There has been an increasing argument that establishment of urban environmental planning with emphasis on air pollutant emission process is essential to abate air pollution in urban life. To obtain fundamental informations for basis of urban environmental planning, we discussed emission of NO_x yielded by urban activity and thermal consumption of it, which will make causal chain pollution process shown in Fig. 1. Amount of NO* emission from various artificial sources in Japan and these thermal consumption were estimated (see Fig. 2), And emission structure which consists of combination ; emission, thermal consumption, and urban activity, was analyzed from the view point of four main factors ; furnace type, fuel and material type, type of emission source activity (for example, industry type of factory), and regional variance. The present study provided following conclusions. * Emission state from each type of source activity can be explained by component of mean emission factor and thermal comsumption (see Fig. 3). *Thermal consumption state of urban activity is determined by its activity amount (for example, monetary product output) and degree of dependency on thermal consumption (see Fig. 4). *There is a definite relationship between types of emission source activity and using furnaces, which is not influenced by regional variance, and a particular combination is seen in furnace type and using fuel and material type (see Fig.5-8). In this present study we showed that type of emission source activity is the comprehensive factor in determina-tion of emission state through the combination of furnace type and fuel and material type, and proposed the idea of classification of emission source activities (see Table 1). In our study, Part 2, we will discuss regional characteristics of emission, which is determined by compound location of emission source activity reflecting land use pattern.
