Abstract
Recently, due to the importance of climate change issues, it has been studied from different angles, and as a result, numerous articles have appeared in the literature. Nevertheless, there are few works on the analysis of climate change problems based on multi-criteria decision-making methods. The application of multi-criteria decision-making methods in this issue ensures as accurate results as possible because the weighting coefficients of the criteria are determined mathematically, and not based on subjective assessment. With this in mind, this study analyses the climate change performance of the G7 countries based on the AHP (Analytic Hierarchy Process) and CODAS (COmbinative Distance-based ASsessment) methods. The method was implemented based on available data of CCPI (Climate Change Performance Index) criteria for 2024. According to the AHP method, the most important criterion is greenhouse gas emissions. By reducing greenhouse gas emissions, the negative effects of climate change on the G7 countries can be mitigated. In terms of climate change performance, Germany ranks first. Ranking after Germany: European Union, United Kingdom, Italy, France, Japan, United States and Canada. Climate change is greater in the European Union than in the United Kingdom, Japan, the United States, and Canada. Climate changes in Germany are greater than in Italy and France. Climate change in Italy is greater than in France. However, regardless of the differences in climate change among the G7 countries, in order to mitigate the negative effect of climate change, it is necessary to reduce greenhouse gas emissions, increase the use of renewable energy in total consumption, and define an adequate climate policy strategy.
