Abstract
This paper provides an overview of greenhouse gas (GHG) emissions in Japan and, as an example of a major city, GHG emissions in Kitakyushu City. It highlights issues in current methods for estimating GHG emissions at the municipal level. Specifically, the current approach, which allocates national or prefectural emissions based on local activity levels, fails to appropriately reflect or analyze the impacts of municipal policies and citizen initiatives. In
response, the paper reviews efforts and technological trends aimed at detailed monitoring of energy consumption across the residential, commercial, and transportation sectors. Achieving carbon neutrality requires starting with the collection and analysis of accurate data.
