The authors have developed the ALICE model, which calculates reduced air pollutant emissions by the greenhouse gas mitigation measures. The model developed here has been applied to a local government in order to estimate the concrete, effects on air quality from the mitigation measures until 2010. Main findings are as follows: 1) The measures in the most intensive case, which will reduce CO₂ emission by 23% with compared to a reference case in 2010, would have effects decreasing both NO_X emission and PM emission by 11-12%. 2) The voluntary action program by steel industry and the dissemination of hybrid cars would have significant effects on the emission reduction of CO₂ and NO_X. 3) In transport sector intensive measures, which would reduce CO₂ emission substantially, don't have similar effects on PM emission.
