ESTIMATION OF INDIRECT EMISSIONS IN EACH MUNICIPALITY AND COMPARISON TO DIRECT EMISSIONS

Abstract

The serious further efforts on CO₂ and other green house gases emission reduction by global climate change mitigation remain as an urgent global issue to be solved. In order to consider the global warming mitigation measures at local level, both direct and indirect CO₂ emissions should be estimated at the municipal level and compared the spatial distribution with each other. The objective of this study is to estimate both direct and indirect emissions by municipalities in Japan and compare these geographical distribution. From the viewpoint of the emission responsibility, this study focuses on the indirect emission which means CO₂ emission from different CO₂ emitting regions of each sector whereas indirect emission means CO₂ emission from the regions where the commodities are consumed according to expenditure of money on the items for household's daily life. As the result, the spatially explicit emissions are mapped as area cartogram from the viewpoint of both direct and indirect CO₂ emission. The result of indirect emission is especially important in view of the emission responsibility.
