We develop methodology and set of modeling tools to determine tradeoff s associated with different mix of greenhouse gas emission countermeasure technologies to reduce the net emission due to the activities linked with an urban environment. To apply the methodology and tools are applied to Liaoning province in China, we analyze the CO2emission structure in the region by utilizing input-output tables. The result indicates steel and power generation industries have large potential of CO2reduction. Construction demand induces large CO2emissions in various industries. We also apply the analysis to SO2 emissions considering the environmental situation in the region. Since the measures of emission reduction are related between each other, the total effect of multiple measures should be consistently evaluated.
