We establish the standard emissions of CO₂ from the work of construction, demolition/scraping and renewal /maintenance and get these following results.
1. We establish the standard emissions of CO₂ per area from the work of construction, demolition/scraping and renewal/maintenance of the urban facilities as well as buildings by calculating 5 years construction work in Nagaoka city to facilitate comparison of scenarios for the urban restructuring.
2. We create 3 scenarios for compactization for the urban image of Nagaoka in the year of 2050. They are Market Scenario, Monocentric Scenario and Polycentric Scenario.
3. By evaluating long-term CO₂ emissions which includes both the reconfiguration period and the following operation period, we conclude the polycentric Scenario is the most desirable toward compact city among three sceinarois.
