The Institute of Energy Economics, Japan

Purpose of IEEJ/Our Vision


The Institute of Energy Economics, Japan was established in June 1966 and certified as an incorporated foundation by the Ministry of International Trade and Industry in September that year. The aim of its establishment is to carry on research activities specialized in the area of energy from the viewpoint of the national economy as a whole in a bid to contribute to sound development of the Japanese energy-supplying and energy-consuming industries and to the improvement of people's life in the country by objectively analyzing energy problems and providing basic data, information and reports necessary for the formulation of policies. With the diversification of social needs, IEEJ has expanded its scope of research activities to include such topics as environmental problems and international cooperation closely related to energy. In October 1984, the Energy Data and Modeling Center (EDMC) was established as an IEEJ-affiliated organization to carry out such tasks as the development of energy data bases, building of various energy models and econometric analyses of energy. In July 1999, EDMC was merged into IEEJ and began operating as an IEEJ division under the same name, i.e., the Energy Data and Modeling Center.
IEEJ has provided data and information related to energy, environment, Middle East, and so on as non-profit organization by using funds from over 100 member companies so far.

Our Mission

Mapping the Energy Future

Our Purposes

The Institute of Energy Economics, Japan has been conducting specialized research activities in the areas of environment and energy economics for 50 years. According to the 2015 Go To Think Tank Index from the University of Pennsylvania, the Institute progressively gained recognition and now ranks Best Energy Think Tank in the World.

The global energy situation is changing constantly, often in dramatic and very complex ways. For example, the Great East Japan Earthquake of 2011 has given rise to serious difficulties in the formulation of energy and nuclear power policies not only for Japan but for many countries around the world.

A stable and secure supply of energy is the bedrock of our daily lives and economic activities. It is therefore crucial to pursue a multi dimensional equation that would simultaneously maximize Energy security, global Environmental issues, economic Efficiency, as well as Safety measures and overall Macro-economic impact (”3E’s+S+M”).

IEEJ dedicates a portion of its resources to meet the particular needs of its member companies. The Institute also provides numerous timely reports and studies regarding the challenges facing the world in general, often leading to policy and company strategy recommendations, both domestically and internationally. As such the Institute is constantly Mapping the Energy Future by adopting a neutral and scientific stance, through a series of comprehensive studies and recommendations that would incorporate fact-based researches on energy and environmental issues, as well as geopolitical and economic analysis. With the support of highly skilled professionals and strategic advice from distinguished fellows from around the world, IEEJ is actively involved in a wide range of researches and will continue to provide policy solutions and/or recommendations in research fields such as:
Energy (fossil fuels, electricity, renewable energy and nuclear energy),
Environment (global warming, energy efficiency),
Energy Economics and Modeling (supply and demand analysis and energy data), and
Geopolitical and Strategic Research (Middle East and worldwide developments).

IEEJ constantly reviews and identifies current issues for researchers to pursue and to write about. IEEJ’s regular activities include the provision of several short- to long-term Outlooks throughout the year. The Institute regularly publishes analysis of market developments (such as shale gas, the Russian situation, LNG prices etc…). IEEJ also holds and organizes domestic & international conferences and seminars and often prepares short summaries of the event’s objectives held within its premises.

Through these activities IEEJ intends to serve as a world leading think tank, located in Japan, representing the interests of the global community within a world in constant evolution.

Our Vision

We would like to announce that “IEEJ Vision” has just been established and we have started work to implement it from this April. The “IEEJ Vision,” subheading “Considering the Energy-Environmental Issues of Japan and Asia from a Global Perspective and Proposing Policy Solutions,”(revised on October 1, 2008) defines “5 focusing research areas” together with 3 main points, “active fields, expertise that we should develop and organizational operation.” We aspire to become the “No 1 Think Tank” and the leading voice in Japanese and Asian energy-related issues and global environmental subjects. We greatly look forward to your continued support of our institution.
