Abstract

Tenggilis Mejoyo Sub-district, Surabaya, has significant potential for Green Open Spaces (GOS) to support carbon emission reduction in urban areas. This study aims to analyse the carbon stock potential of GOS in the area and evaluate their role in carbon emission mitigation. Primary data were collected through field surveys measuring tree diameter and height using the allometric method, while secondary data were obtained from relevant literature. The results show that the total area of green lanes in Tenggilis Mejoyo is 33,227.5 m², with a carbon storage capacity of 275.35 tonnes. This capacity can only absorb 0.33% of the total carbon dioxide (CO₂) emissions from the transport sector in 2019, which amounted to 83,336.73 tonnes, leaving 83,061.38 tonnes/year unabsorbed. An additional 145.97 hectares of GOS are required to offset the remaining carbon emissions. This study also shows that active parks were not included in the carbon stock analysis, which are likely to increase the overall contribution to carbon sequestration. Therefore, further research on carbon stocks in active parks within Tenggilis Mejoyo is highly recommended. The results of this study are expected to serve as a basis for environmental policy planning and more effective GOS management in Surabaya.

Abstract

Green belts play an important role in reducing greenhouse gas emissions in urban areas. This study aims to determine the total carbon stock and carbon absorption capacity of vegetation along the green belt of Dr. Ir. H. Soekarno IIC Road (MERR) in Surabaya, and to analyze the extent to which vegetation can reduce carbon dioxide (CO₂) and carbon monoxide (CO) emissions produced by motor vehicles. The method used in this study involves direct measurement of vegetation parameters such as tree diameter and height, which are then processed using biomass estimation and carbon stock conversion factors. In addition, CO₂ emissions are estimated based on traffic volume data and emission factors for each type of vehicle. The results show that the vegetation in the MERR IIC green belt is able to store a certain amount of carbon and has potential in absorbing CO₂ emissions, although it is still not proportional to the total emissions produced by motor vehicles per day. Therefore, improving the quality and quantity of vegetation in urban green belts is crucial to support air pollution control efforts in urban areas.
