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 (CO 2 ) emissions from industrial and residential activities in the Sukorejo Village affect the air quality in Gresik City. This study calculated the CO 2 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 CO 2 emissions. Calculation of the CO 2 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 CO 2 emission absorption was based on the area of green open space in the Sukorejo Village, Gresik. The results of the study show that the CO 2 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 CO 2 emissions of 129.19 tons/year. These results indicate that the vegetation in the green space is still not able to absorb the total CO 2 emissions from industrial and residential sources. Therefore, it is necessary to add vegetation or private green open space to absorb all the CO 2 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 CO 2 emissions. In turn, scenario 5 requires the addition of several types of plants.
