Creation of carbon footprint originating from road transportation in Turkey and digital mapping of it

In this study, the carbon footprint created by the greenhouse gases originating from road transportation in Turkey was calculated. In emission calculations, the methodology recommended by the Intergovernmental Panel on Climate Change and determined by the tier-1 and tier-2 approaches was used. As a result of the study, it was observed that the CO2 emission, which was 95,689 GgCO2 in 2018 according to the tier 1 method, decreased to 92,424 GgCO2 in 2020, and the CO2 emission, which was 417,359 GgCO2 in 2018 in the tier-2 method, decreased to 404,631 GgCO2 in 2020. Among the fuels used, it was determined that the diesel fuel type had the highest CO2 emission in both methods. Among the provinces, it was determined that Istanbul, Ankara and Izmir have the highest CO2 emissions, respectively. CO2 emissions were calculated for each province and presented visually on maps prepared using the ARCGIS method.
