近年,UNEP(国連環境計画)は,持続可能な発展は持続可能な生産と同時に持続可能な消費によって可能となるとして,消費の見直しを呼びかけている.また,エネルギー経済学者達の間でリバウンド効果(エネルギー効率改善目的の技術進歩がかえってエネルギー消費を増加させてしまうという効果)の議論も盛んになっているが,こうした流れの中で,われわれがかねて取り組んできた産業連関的環境家計簿分析は,新たな分析目的を持つようになった.本論では1985-90-95接続環境分析用産業連関用を用いてこの新たな分析課題に取り組むため,家計消費が引き起こす環境負荷の変化を3つの効果-消費構成比変化の効果,所得増加の効果,技術変化の効果-に分解し,持続可能な消費の問題にアプローチした.

<p>The objective of this study is to analyze, from a comprehensive perspective, the economic and environmental effects induced by constructing and operating hydrogen utilization systems presented by METI's roadmap. We focused on a marine transport system for hydrogen produced offshore, hydrogen gas turbine power generation, fuel cell vehicles (FCVs) and hydrogen stations, as well as residential fuel cell systems (RFCs). In this study, using an Input-Output Table for Next Generation Energy Systems (IONGES) with newly established renewable energies and hydrogen-related sectors, we evaluated the induced output, labor and CO₂ from construction and operation of these hydrogen technologies using a uniform approach. Initial investments in facilities based in foreign countries that produce hydrogen, transport it through organic hydride, and supply it to a power station of 1 GW capacity yield an induced production of 2.7 times. This investment can exploit a new opportunity for the utilization of unused renewable energy sources that are abundantly available in foreign countries and reduce significant CO₂ emissions. Additional investments in domestic hydrogen supply systems, FCVs, and RFCs yield an induced production of 2.6 times each. From a comprehensive point of view, the construction of a hydrogen utilization system may result in cost and CO₂ reductions.</p>
