Japan’s Contribution to Cool Earth


  • Kikkawa, Takeo


The purpose of the “Cool Earth 50 Plan” announced by the Japanese Government is to cut global greenhouse gas emissions to half the current level by 2050. This paper focuses on the following two points: (i) How compatibility between environmental protection and economic growth could be made, and (ii) How Japan should contribute to “Cool Earth” on a long-term basis. In regard to point (i), this paper makes clear the validity of energy conservation and technological innovation. One of the most important innovations is CCS (Carbon Dioxide Capture and Storage) / EOR (Enhanced Oil Recovery) technology. In regard to point (ii), this paper introduces two unique Japanese methods for cutting global greenhouse gases, those are the “Top Runner Program” and the “Sector by Sector Approach”. The former is effective in the residential, commercial, and transportation sectors, and the latter is valid in the industrial sectors.
