Özet:

The rapid increase in industrialization in societies causes environmental problems to emerge as an important problem. In all societies, the approach to the environment is becoming more sensitive and it is observed that studies on environmental performance have started to increase. The Global Green Growth Index (GGGI), an important measure of environmental performance, has been publishing reports comparing countries' performance scores since 2005. This study examines the changes in the rankings in the post-2010 period by using the Global Green Growth Index data to determine the environmental performance rankings of G7 countries and Turkey. The main objective of the study is to contribute to the realization of sustainable development by determining the position of G7 countries and Turkey according to GGGI. In the study, the performance ranking of the countries for the years 2010-2020 was made by using the ENTROPI and CRITIC weighting methods, which are among the Multi-Criteria Decision Making methods (MCDM), and the EDAS ranking method. In addition, sensitivity analysis was performed to determine the importance of criterion weights affecting performance rankings. While Germany exhibits the best performance in general, it is observed that Turkey performs lower than developed countries. It has been determined that the indicator of efficient and sustainable resource use has a significant impact on the environmental performance of countries.
