Belgrad forest carbon sequestration and life cycle carbon footprints of İstanbul
İnci Çağlayan, Aysel Sadak Mercan, Fatmagül Kılıç GülIncreases in the carbon dioxide (CO2) concentration in the atmosphere is one of the most important environmental problems of today. In addition to the increases due to industry, human activities such as heating, transportation, and electricity consumption contribute to this increase gradually. There are different measures to reduce the amount of carbon concentration in the atmosphere, one of which is the use of terrestrial ecosystems such as forests, which gain importance due to their carbon sequestration potential. On the other hand, the values of greenhouse gas emissions (GHGs), especially CO2, and the carbon values of forest sinks and sequestrations (FS) also vary spatially. We examined the quantities of the human activities' annual carbon footprint (CF) with the FS carbon value of the largest forest area of İstanbul’s two districts as a sample calculation. CF values were calculated by using life cycle survey data made for another study in 2014. The survey applied to geomatic engineers concerning six categories: houses, flights, cars, motorbikes, bus and rail, and secondary data (food, clothing, services, trade, etc.). The sink value and the annual carbon sequestration for the Belgrad forest were calculated using the formulas set by the Intergovernmental Panel on Climate Change (IPCC) and the values of local coefficients and forest plans inventories. According to the results of the study, approximately 6 475 500 t CO2e was released annually in two neighboring districts. The forest continues to store an average of 13 171 tons of carbon or 48 294 tons of CO2e each year.
