As the center of human activity, a city needs supporting infrastructures. One of the essential city infrastructures is the road to provide transportation and mobilities within the city. A motor vehicle is one of the famous transportation modes in the city. In a developing country like Indonesia, motor vehicles such as private passenger cars and motorbikes are still becoming the primary selection of transportation modes. The number of car and motorbike are always growing every year, especially in metropolitan cities such as Jakarta, Surabaya, Medan, and Semarang. This circumstance will have an impact on environmental condition like degradation in air quality, escalation in air surface temperature, and health issues. Carbon emission from fossil fuel combustion will increase the concentration of greenhouse gasses in the atmosphere. In more extended time, it will contribute to global warming and changes in urban climatic condition. This study is being conducted to show the open green space distribution and to the carbon sequestration capability, especially towards the carbon emission from motor vehicles. This study uses Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Atmospherically Resistant Vegetation Index (ARVI) generated from Landsat OLI-TIRS and Sentinel-2 imageries to map open green space distribution. Tree stand parameters like diameter breast height (DBH) and tree height collected from field observation are being utilized in the allometric equation to extract biomass and carbon stock information. The results from this study are expected to describe the condition of open green space and its capability to sequestrate carbon from the motor vehicle in Semarang.
