Environmental problems are becoming more visible and this detrimental situation, negatively affecting the national economies. Therefore, the economic effects and costs of environmental problems have become an important research topic in the field of economics. In the literature, carbon dioxide (CO2) emission is generally used as an environmental pollution indicator. It is thought that renewable energy investments and innovative approaches to the environment can overcome environmental problems in the long run. In this study, the effect of environmental innovations (ETI), renewable energy (REC) and growth (GDP) on CO2 emission examined for 8 countries, listed according to the IMF's classification in the G-20 country group between 1993 and 2018. Durbin-H cointegration and FMOLS tests are used in the analysis, considering the cross-sectional dependency and heterogeneity. According to the analysis results, there is a long-term relationship between the variables. The effects of the variables considered on CO2 emission differ by country, the change in REC and GDP for the panel generally reduces CO2 emission, while the increase in ETI increases CO2 emission. |
