The Hasanuddin University Faculty of Engineering in Gowa is the largest engineering campus in South Sulawesi. The lecture activities are very complex which are not only teaching and learning but also households and offices activities. Therefore, it is important to know the mapping of existing carbon footprint on the campus due to the complexity of the campus activities. The purpose of this study is to determine the level and mapping of the carbon footprint on campus. The method used is to halve emissions into primary and secondary carbon footprint emissions. The results of this study indicate that the greatest emissions is generated from the secondary carbon emissions which is electricity consumption amounting to 1,315,429.63 KgCO2/Year, and the lowest emissions is resulted from the use of paper at 49.39 kgCO2/Year. For the buildings the highest CO2 emissions is generated from the Architecture Department building at 289,176.26 KgCO2/year and the lowest CO2 emissions is generated from the Naval B Department building at 20,599.20 KgCO2/year. The mitigation scenario in reducing CO2 emissions effectively is by implementing Earth Hour for 1 hour every month which can reduce electricity consumption by 582,541.78kWh/Year and CO2 emissions at 164,428.70 KgCO2/year. The effective scenario to decrease waste is by implementing 3R with 2% waste reduction which is 167,332.79 Kg/Year and emissions CO2 are 4,772.41 KgCO2/Year.

The economic growth will increase the transportation sectors roles in supporting the achievement of development goals. But transportation activities have negatives impact, where one of the negative impact of transportation activities is the high levels of pollutants due to emissions or release of smoke from motor vehicles. This study aims to determine the capability of green open space that exists, especially in the ability of trees and shrubs in absorbing carbon monoxide and carbon dioxide emissions generated by motor vehicles operating in Balai Kota Makassar. The research is qualitative. All data required for the analysis of the research are primary data or data obtained directly in the field. Primary data in this research are data obtained by counting the number of vehicles and the area cover by vegetation canopy. In this research, zonation system is applied because each area has different green open space requirement based on the emission load generated by motor vehicles passing in the area so that the research location is divided into 4 zones. To calculate the vehicle’s emission, it applies the equation of emission strength, and to calculate the emission absorption by vegetation is use vegetations area covers. The results showed in zones 1, zone 2 and zone 3, green open space existing already can absorb 100% carbon dioxide emissions and carbon monoxide. But in zone 4, green open space existing cannot absorb 100% carbon dioxide emissions and carbon monoxide.
