Assessment of carbon stocks and CO2 sequestration rate through urban trees in city Faisalabad, Pakistan

Urban trees serve as CO2 emissions absorbers resulting from activities of human in the city, as well as an indicator of atmospheric quality and a pollution scouting device. The importance of trees in the planning process for the sustainable development of cities cannot be overstated. The purpose of this study was to assess the potential of “carbon stocks” and tree stands in Faisalabad that had the highest carbon stock and CO2 sequestration rates. The study was carried out in September-November 2019 in the Faisalabad city area covering 20 locations. The biomass calculation and carbon stock estimation is based on Diameter at Breast Height (DBH) is measuring by utilizing an “allometric equation B = 0.11 ρ D (2+0.62)”. Allometric equations containing the definite wood density of each tree species are used in data processing. The findings depicted, potential of “carbon stocks” in Faisalabad trees is 34.782 + 41.84 kg/ha with Jinnah Park, and Razabad is 5.033 + 2.70 kg/ha. Overall, the maximum CO2 sequestration rate is 16.096 + 16.37 kg/ha/year and the minimum in Razabad with 1.893 + 1.13 kg/ha/year
