It rarely discusses indirect energy use and emissions. On the other hand, the responsibility to global CO2 emissions in Taiwan usually use production based calculation. The purpose of the study is to use hybrid-input-output analysis to calculate direct and indirect emissions per unit of output, and apply to industry, the issue of trade, and to clarify the production and consumption based measurement of the difference in CO2 emissions. 　　The analysis results as follows: 1. During 1986 to 2004, direct energy intensity, embodied energy intensity, direct CO2 intensity and embodied CO2 intensity in 26 industries declined in the first stage and arose in the second stage. 2. In six non-energy industries, traditional industries and basic industries clearly trended to low rates of added value and high CO2 emissions. 3. Within high energy intensity industries, textiles, midstream, and downstream petrochemical industries trended to deteriorate. 4. Exports CO2 intensity and imports CO2 intensity in Taiwan were roughly the same, but the emissions embodied in exports were higher than imports, and the gap has widened more and more. The consumption based computation CO2 emissions was lower than production based computation.
