In this study, it was examined whether CO2 emissions, which are the main cause of climate change, show convergence behavior with data for the period of 1946-2019 in 17 European countries. In the study, ADF linear unit root test, LNV (1998), KSS (2003) and Sollis (2009) nonlinear unit root tests and Nahar-Inder (2002) technique which allows convergence even in the case of unit root were used. According to the findings obtained, 12 countries exhibited convergence behavior in ADF test, 6 in LNV (1998) test, 10 in KSS (2003) test and 9 in Sollis (2009) test, while convergence behavior was observed in 16 of 17 countries according to Nahar-Inder (2002) technique. Based on this, it can be said that the Nahar-Inder (2002) technique gives stronger results compared to unit root tests. This determination can be assessed in the form that countries that are parties to international agreements aimed at preventing environmental degradation related to the use of fossil fuels can implement common policies. Within this framework, it is presented as a policy proposal of the study that international agreements on combating climate change should be expanded and provisions and institutions that will increase the power of sanctions should be created.
