Abstract:

Environmental problems are on the agenda of all countries since they have reached severe levels and are a global problem. It is seen that countries need to take various measures to solve environmental problems. The aim of this study is to measure the environmental performances of twenty-four OECD and EU member countries that are among the top fifty in the world in gross domestic product with CRITIC and MABAC methods, which are multi-criteria decision-making methods, taking into account the criteria in the Climate Change Performance Index (CCPI) and Environmental Performance Index (EPI). The importance levels of the Climate Change Performance Index and Environmental Performance Index criteria for 2021 were calculated separately with the CRITIC method. Then, the environmental performances of selected countries for 2021 were calculated by applying two methods: integrated CRITIC – MABAC and equally weighted criteria – MABAC. Finally, the environmental performances of the countries were measured by evaluating the criteria in both indices together. The results obtained were compared with the rankings in the index reports and the applicability of the methods used in these indexes was examined.
