The purpose of this study is to make a comprehensive assessment of the measures for reducing CO_2 emissions from man's future global energy system through the use of a global energy model New Earth 21. In the framework of the energy model built here, the whole world is geopolitically divided into ten regions so that it can explicitly evaluate the differences in regional economic and geological conditions. The model can assess the various technology options up to 2050 by optimizing the sum of the total energy system cost. As specific technology options, the model takes into account energy conservation in end-use and conversion sectors, utilization of various renewable energy resources, disposal and recycle of CO_2 recovered, and innovative system technologies. The results of the study suggest that the CO_2 problem can not be easily settled by any single technology option. However, they also suggest that if those options are reasonably combined with one another, there exist great CO_2 emission reduction potentials to stabilize annual global CO_2 emissions at the present level.
