CO2 is the primary contributor to global warming, and also most significant anthropogenic emission gas in cities. This study investigates near-surface spatiotemporal variability patterns at community scale address critical gap urban high-resolution measurement promote carbon neutrality. Combining fixed mobile monitoring across five representative communities (1-km2 coverage) with two-hour temporal precision 20 m spatial resolution, results revealed average concentrations of 440–480 ppm, exhibiting bimodal diurnal cycles highlighting divergent behaviors. Three peaked during 17:00–19:00 LT, while two 08:00–10:00 LT. Spatial correlation analysis identified dominant patterns: road-adjacent “externally dominated” hotspots “internally zones elevated intra-community levels. Spearman analysis, Random Forest, Geographically Temporally Weighted Regression models quantified morphology element contributions, demonstrating that building exerted time-varying impacts communities. Meanwhile, external traffic contributed 18–39% concentration variability, internal energy consumption drove localized peaks. The findings indicated apart from sources, micro-scale design elements regulate distribution. approach provides actionable insights for optimizing layouts infrastructure mitigate emissions, advancing neutrality targeted planning.

Decarbonizing the transportation sector is critical for sustainable development, particularly in rapidly urbanizing countries like Turkiye. This study analyzes fuel demand elasticities diesel, gasoline, and LPG across 12 NUTS-1 regions of Turkiye 2022, using a panel random effects SUR approach. The model accounts regional variation interactions, producing robust estimates that uncover significant spatial temporal differences consumption patterns. Uniquely, diesel displays significantly positive price elasticity, challenging conventional assumption inelasticity. Gasoline moderately price-sensitive, while appears relatively unresponsive. Strong cross-price elasticities—especially between gasoline—point to substitution can inform more adaptive policy frameworks. Seasonal fluctuations Istanbul’s outsized impact also shape national trends. These findings underscore need differentiated region- fuel-specific strategies. While higher gasoline taxes may effectively reduce demand, lowering use will require complementary measures such as infrastructure upgrades, behavioral incentives, accelerated adoption alternative fuels. advocates regionally adjusted carbon pricing, removal implicit subsidies, targeted support electric hybrid vehicles. Aligning fiscal tools with actual behavior enhance both efficiency equity transition low-carbon system.
