Abstract

<p> In this paper, we created a regression equation to calculate the annual emission per capita for each third-order mesh using individual data of household CO2 statistics survey by MOEJ. This made it possible to show the current per capita emissions from the use of residential and passenger-car by each third-order mesh. Regression formulas were created separately for residential and passenger-car, and the prediction performance was evaluated based on comparisons with emission estimation models from previous studies, using statistics for each prefecture as verification values. By using the regression equation of the hous-ing created in this study and the model for estimating automobile emissions of Chen et al. (2018), the per capita emissions by mesh, which is highly consistent with the statistics by prefecture, can be obtained. The value obtained by adding the emissions per capita the use of residential and passenger-car has many meshes centered around 3t-CO2, and the ratio of the passenger-car emission to the added value is 15-65%. The result is consistent with the analysis result of each municipality conducted by Matsuhashi et al. (2018).</p>
