The international research exchange project is to promote research exchange to solve the global environmental problem by NEDO with cooperation with RITE in inviting researchers from overseas to Japan and sending Japanese researchers overseas. As to global environmental related technology, to make broad research exchange between advanced overseas researchers and Japanese ones, eight researchers were invited and a joint research was made. Also, eleven researchers from Europe and the U.S. were invited to the West Pacific electrochemistry symposium, the international workshop on nitrous oxide emissions, and the international forum on environmental catalysis. To make effective promotion of researches of Japanese researchers and grasp the trend of research development overseas, five researchers were sent to universities and research institutes in Europe, and at the same time thirteen researchers were sent to international conferences and symposiums on global environmental industry technology. As a result, found is how fundamental studies on global environmental technology are progressing overseas. It is thought to be important to make further efforts for international exchanges. 107 refs., 105 figs., 24 tabs.
