Abstract

Urban areas globally are escalating contributors to carbon dioxide (CO) emissions, challenging sustainable development. This study proposes a novel micro-scale approach utilizing GIS to quantify CO emission spatial distribution, enhancing urban sustainability assessment. Employing a “bottom-up” methodology, emissions were calculated for various sources, revealing Isfahan’s urban area emits 13,855,525 tons of CO annually. Major contributors include stationary and mobile sources such as power plants (50.61%), road and rail transport (17.18%), and residential sectors (21.78%). Spatial distribution mapping showed that 81.68% of CO emissions originate from stationary sources, notably power plants. Furthermore, mobile sources, including road transport, contribute 17.16%, with emissions concentrated in main urban arteries. Agricultural machinery adds 1.14% of emissions, spatially distributed across Isfahan’s agricultural lands. Integration of emissions maps depicts the city’s total CO emissions, highlighting sectoral contributions. Despite limitations in data granularity, this study provides valuable insights into urban CO emissions dynamics, facilitating targeted mitigation strategies. Quantitative achievements include precise CO emission quantification and spatial distribution mapping, crucial for formulating effective urban sustainability policies.
