Abstract
Recently many municipalities and governments have stated that they will promote a compact urban layout as one of countermeasures for reducing CO2 emissions. It should be easy for municipalities to confirm environmental effects of compact urban layout, but quantitative information about CO2 reduction caused by compact urban layout, based on present state and redevelopment projects, are not yet completely available. An objective of this study is to evaluate the various compact urban layout scenarios that use SLIM CITY model from the viewpoint of CO2 reduction. Overall, this study shows that a corridor type urban layout scenario is significant from sustainable point of view.
