鉄鋼部門の地域別エネルギー効率の評価

抄録

The steel production in China has rapidly increased since 2000. India also would strengthen their capability of steel production in the early stage. Under the situations, the improvement of energy efficiency in the steel sector is one of the most important measures for mitigating climate change. The global communities are now recognizing that "sectoral approach" will strongly support the diffusion of energy efficient technologies. The "sectoral approach" can be one of the effective frameworks after 2013; however, comparable indicators of energy efficiency among global countries/regions are needed for the discussion of the framework. This paper evaluates regional energy efficiency in iron and steel-making sector, i.e., energy consumption per ton of crude steel production. IEA indicates that there are some issues, e.g., system boundary, allocation, and data availability, for directly estimating regional energy efficiency under current IEA statistics status. This study overcomes these issues by using many sources and multistage frameworks. The estimated regional energy efficiency is useful and essential to discuss concrete measures for energy efficiency improvement in the global iron and steel sector.
