Mitsui & Co., Ltd. ("Mitsui") participates in Perenia Pty Ltd, a Sydney based environmental consulting firm which aims to work with Australian businesses in realizing opportunities while managing risks as Australia progresses towards a low carbon economy with the introduction of the Carbon Pollution Reduction Scheme (CPRS). Perenia is a joint venture involving two of Australia's leading clean technology companies-Snowy Mountains Engineering Corporation ("SMEC") and Pacific Hydro-and Mitsui. With participation in Perenia, Mitsui takes the lead in entering into the Australian carbon market, which has high future growth potential.

Business practice in Australia needs to be changed because not only the new legislation but shareholders and the wider community are demanding companies and organizations take a proactive role in reducing their environmental impact. Perenia will assist businesses to reduce their emissions by tailoring solutions to find optimal strategies. Perenia will not only identify solutions but also apply the technical and financial resources of its shareholders to the successful implementation of abatement projects. As Australia is in a close business relationship with Japan, many Japanese firms have operations in Australia. Perenia aims to provide its services to these businesses as well.

The three partners in Perenia (Mitsui, SMEC and Pacific Hydro) are all experienced in developing renewable energy projects to reduce greenhouse gas emissions and are already realizing substantial international business opportunities from emissions trading. Using its experience and expertise, Perenia aims to develop renewable energy projects, under the Clean Development Mechanism (CDM) of the Kyoto Protocol, that create carbon credits, mainly in Asia-Pacific and South America

Since 2000, Mitsui has been active in developing CDM projects, and through Perenia, Mitsui aims to boost its effort to develop renewable energy CDM projects and to increase transactions of carbon credits generated from such projects. Mitsui will also continually search for opportunities to invest in renewable energy projects, such as solar and wind.
