Global environmental problems, especially global warming caused by the accelerative accumulation of carbon dioxide in the atmosphere, are of great importance for humans. The world's population is now approaching 6 billion, and is still increasing. Developments in communication systems and transportation tools have made the circulation of information, technologies and materials easier, which results in rapid economic growth, particularly in the East and Southeastern Asian countries. Increased affluence leads to an increased consumption of fossil fuels. Inevitably, this leads to an increase in carbon dioxide emission and environmentally hazardous materials which in turn precipitates climatic changes on a global scale. Recent studies showed that the increase in carbon dioxide emission for last year was the highest in the past seven years, and the total amount of carbon dioxide emission from all over the world reached 6.5 billion tons. Furthermore, one cannot overlook the report which appeared recently in Nature, that the floor-area of the iceberg in the South Pole has already decreased by 25% in the past five decades. Over 260 scientists and engineers from 21 countries who had a strong interest and wished to contribute to solve the carbon dioxide problem attended this conference. The papers presented in this volume cover most of the possibilities of the chemical conversion of carbon dioxide.
