Keidanren Announces Results of Questionnaire Survey on
Energy and Low-Carbon Technologies
In the Japan Revitalization Strategy, the Japanese government
decided that “in order to formulate the Proactive Diplomatic Strategy on
Global Warming by which Japan would contribute to the world throughtechnology, the government develop a new Environmental Energy
Technology Revolution Plan at the Council for Science and Technology
Policy so as to promote research and development.” Based on thegovernment decision, the Council for Science and Technology Policy
established the Commission for the Environmental Energy Technology
Revolution Plan (Chairman: Kazuo Kyuma, full-time member of theCouncil for Science and Technology Policy), which is scheduled to compile
a new Environmental Energy Technology Revolution Plan near the end ofAugust.
Against this backdrop, the Keidanren conducted a questionnaire
survey among members of the Subcommittee on Policy of the Committee
on Energy and Resources and the Subcommittee on Global Environmentof the Committee on Environment and Safety addressing technology
fields which require special focus in terms of research and development
for practical application in 2050.
