Özet

This study employs the ASAN method to estimate the carbon storage capacity within the urban–rural tree canopies of Ankara’s central districts. The results have been compared with carbon storage estimations employing the methodology delineated by Myeong–Nowak–Duggin, aiming to ensure heightened data reliability. Çankaya has a relatively high carbon storage rate with 16.887,622 ton according to ASAN method and 22.323,044 ton according to the Myeong–Nowak–Duggin method. Etimesgut district has the lowest carbon storage capacity with 455.647 tons in the ASAN method and 495.391 tons in the Myeong–Nowak–Duggin method. To contextualize these findings within green area strategies, district-level population-based carbon emissions are compared with district-level carbon storage results obtained via the ASAN method. Carbon emissions are calculated based on literature-derived data regarding individual carbon output in activities such as transportation, shopping, food supply, and energy consumption. Notably, Keçiören district, with its high carbon storage rate, also demonstrates high carbon emissions. Given the highly limited spatial distribution of tree cover, particularly in densely populated areas of the district, urban policymakers should prioritize climate crisis interventions in Keçiören. The study underscores the importance of developing open and green space strategies at the district level to address the climate crisis. By utilizing the ASAN method for carbon storage calculations, local authorities can access vital information to formulate climate-oriented policies for urban–rural expansion.
