Abstract: Increased
concentrations of greenhouse gases (GHG’s) are linked with the increased risk
of global climate change. Urban trees can reduce atmospheric carbon dioxide (CO2), the main
anthropogenic GHG. Urban forest is a widely known carbon reservoir. Woody vegetation, trees and shrubs, sequester CO2 through photosynthesis and store excess
carbon as biomass. Park is the second largest component of urban forest in
Bandung City, and is targetted to be the largest in 2030 .The potentials of carbon
storage and sequestration in city parks in Bandung have not been measured prior to this research. The research found the average density of CO2
storage
(DCS) of City Park is, 4.51 (95% CI, -1.98,
+2.56) ton CO2 per 100 square meter (tonC.100m-2) with total CO2 storage (CS) for parks in Bandung at, 39,278 (-17,244, +22,259) tonC. The average density of
CO2 sequestration rate (DCSR) is, 0.30 (-0.14, +0.21) ton CO2 per 100 square meter per year (tonC.100m-2.Yr-1), with CO2 sequestration rate (CSR) at 2,067 (-1,179, +1,816) tonC.Yr-1. Variables which
significantly affect DCS in City Parks in three
different regression models are, Shannon Diversity Index (H’), Elevation (E),
Sum Dominance Ratio of the Dominant Tree Species (SDRdm),
and Tree Density (TD). Meanwhile, variables which
significantly affect DCSR are, E, TD, and SDRdm. Three
storage and sequestration potential models (Pesimistic, Realistic, and
Optimistic scenarios), which were run for a ten year period, estimated areas
for additinal tree planting between 114,089 – 329,718 m2. The three modeling scenarios have the potential to
increase, within the next 10 years: DCS by, 0.1 – 13.4 tonC.100 m-2; CS, by, 116,3 – 5,126.1 tonC; DCSR by, 0.01 – 0.28 tonC.100 m-2.Yr-1; and CSR by, 13.4 – 863.9 tonC Yr-1.
