A Study on How to Develop Decarbonization Measures with the Decentralised Energy System Utilizing Public Space

A Case Study in Sapporo City Center

Abstract

In recent years, the Japanese government has been promoting the development of energy centers in the construction of energy networks to reduce CO2 emissions. On the other hand, the amount of renewable energy in urban areas is low, making it difficult to achieve decarbonization through onsite environmental measures alone, and there is a need to develop measures in conjunction with offsite environmental measures. The purpose of this study is to clarify how to develop decarbonization measures in conjunction with the construction of energy networks that utilize public space. As a result, it was found that the introduction of off-site measures such as renewable electricity supply in collaboration with other regions and the expansion of support for environmental measures such as subsidies are important to achieve decarbonization in conjunction with the construction of energy networks utilizing public space.
