While energy is a required factor in any kind of economic activity, most environmental problems, such as acid rain precipitation, greenhouse-gas emissions, and exhaustion of nonrenewable resources, seem to be related to overuse of primary energy. It is therefore important to consider energy within the framework of an integrated analysis of natural resources, economy, and the environment. In recent years, many scholars have studied this issue (see, for example, Balistreri & Rutherford, 2000; Jiang, 2002; Lin & Polenske, 1995; Xu et al.,2002; Zhang & Folmer, 1997) in the light of different but traditional input-output models. One kind of theoretical green input-output table, focused on energy, is designed on the basis of our Green Input-output Accounting Framework of Natural Resources-Economy- Environment. Scenario forecasting and analysis for China in 2020 are made. Coal used, without further transformation, mainly for power generation, is the major source of SO2 and CO2 emissions in China, and it will remain so without changes to the final and intermediate demand structures.
