In seeking a basic solution to global environmental problems, efforts to reduce greenhouse gas emissions must occur in conjunction with an expansion of the "3 Es": energy security, environmental protection, and economic efficiency and sustainable economic growth. A steady supply of energy and the maintenance of the environment must be combined to form two sides of the same coin. Achieving such a balance is the key to realizing sustainable economic growth on both a domestic and a global scale. Japan's high-end energy-saving and environmentally friendly technologies could contribute much toward solving these problems throughout Asia, where energy consumption is increasing. In fact, regional revitalization is currently underway in Japan, which has effectively begun to construct a recycling-oriented society that thrives on natural energy. Mitsubishi Heavy Industries, Ltd. (MHI) is actively engaged in developing technologies that transform and use energy in harmony with the environment and that facilitate environmental conservation, restoration, and creation through an expansion of the 3E approach for creating a sustainable global society.
