Building lifecycle carbon emissions considerably contribute to global warming, and urban renewal affects regional emissions and sustainability. Assessing these emissions is vital for low-carbon strategies. Existing studies often focus on single buildings rather than city scales due to the availability of qualified data. This study assesses the carbon emissions during building renewal and to predict future with the scenarios of renewal strategies, demolition, and reconstruction. The central area of Tokyo was selected for case study, where the buildings are undergoing a dramatic renewal. GIS is used to manage the database from multiple sources including building footprints, land uses, structure type etc. Carbon emissions was estimated by integrating the geospatial data with AIJ-LCA database. Results show different renewal strategies greatly impact emissions, providing insights for low-carbon planning and offering data and suggestions for low-carbon strategies in urban renewal projects.
