Absorption of Carbon Dioxide Emissions from Industrial and Residential Sources by Green Open Space in Sukorejo Village, Gresik

The Sukorejo Village is a mangrove ecotourism place on the coast of Gresik City and is also located in the Industrial Estate. The carbon dioxide (CO2) emissions from industrial and residential activities in the Sukorejo Village affect the air quality in Gresik City. This study calculated the CO2 emissions from industrial and residential sources in Sukorejo Village, Gresik. In addition, it also estimated the ability of green open spaces in the Sukorejo Village to absorb the CO2 emissions. Calculation of the CO2 emissions from industrial sources requires the data on fuel and electricity consumption, while from residential sources requires the data on population, LPG and electricity consumption. Calculation of the CO2 emission absorption was based on the area of green open space in the Sukorejo Village, Gresik. The results of the study show that the CO2 emissions from industrial sources are 20,224.15 tons/year, while from residential sources are 2,164.63 tons/year. Green open space in the Sukorejo Village which consists of mangrove trees and shrubs is able to absorb the CO2 emissions of 129.19 tons/year. These results indicate that the vegetation in the green space is still not able to absorb the total CO2 emissions from industrial and residential sources. Therefore, it is necessary to add vegetation or private green open space to absorb all the CO2 emissions from industrial and residential sources. There are several scenarios of adding vegetation. Scenarios 1 to 4 require the addition of 1 type of plant that has a high absorption capacity of the CO2 emissions. In turn, scenario 5 requires the addition of several types of plants.
