Cool Earth-Energy Innovative Technology Plan

Last updated: 24 August 2021
This is Japan’s national energy technology strategy that sets out the innovative and essential technologies to be developed and promoted toward the year of 2050. The development of innovative technology is essential in achieving the long-term target of halving global greenhouse gas emissions by 2050 from the current levels under Cool Earth 50, proposed in May 2007. Based on awareness of this issue, an investigative commission comprising key intellectual figures, organized under Akira Amari, Minister of Economy, Trade and Industry, announced the Cool Earth Innovative Energy Technology Program. The commission selected 21 innovative technologies whose development and deployment should be prioritised to achieve the target. In the program, roadmaps with an outlook extending to around 2050 were prepared along with examinations on the effectiveness of the technologies and measures toward dissemination. In addition, the Program aims to strengthen international co-operation to accelerate innovative technology R&D, through existing international frameworks such as the Carbon Sequestration Leadership Forum (CSLF) and APP on clean coal; GNEP and GIF on nuclear; IPHE on fuel cells and IEA implementing agreements generally as well as through exploring new areas for cooperation.Technologies included are:High efficiency natural gas and coal fired power generationIntelligent transport system, fuel cell vehicles, plug-in hybrid/electric vehiclesInnovation to increase efficiency of industrial processing and materials productionInnovation in iron and steel-makingHigh-efficiency housing and building technologies, as well as lighting technologiesStationary fuel cellsHigh-efficiency heat pumpsHighly efficient information device and systemsHigh-performance power storage systemsHEMS/BEMS and local-level Energy Management SystemsThe full report and technology roadmap are available, in English, at:
