Abstract: In order to reduce CO2 emissions, industrial enterprises try to utilise various methods such as obtaining energy from renewable power plants, afforestation and carbon offset. In this study, it was aimed to determine the most appropriate method to reduce CO2 emissions caused by the energy consumption of an automotive industry company. With this study conducted, analytical hierarchy and multimoora methods, which are among the multi-criteria decision-making techniques, were used together to select the optimum method among the CO2 reduction methods. As a result of the study that assesses the effectiveness of hydroelectric power station, solar electrical system, solar thermal energy system, afforestation and carbon offset alternatives from various angles, it is concluded that hydroelectric power plant is the most suitable option for ensuring CO2 reduction for the automotive company. It has been revealed that carbon offset, which is often preferred by companies, is not such an effective alternative.
