Özet:

The aim of this study is to examine the impact of innovations in environmental technologies on CO2 emissions. Based on the 1990-2018 observation period, an empirical study was conducted for Turkey, which is classified as a developing and newly industrializing country (NIC). CO2 emissions, financial development index, GDP, and total environmental technology are included in the empirical model. First, the ADF and PP unit root tests were used to determine whether the model contained unit roots. As a result, it was determined that all variables had unit roots at the level values but were stationary at the first difference values. The ZA unit root test with structural breaks was used to avoid ignoring structural breaks. In line with the findings, it was discovered that under structural breaks, all variables had unit roots at their level values but became stationary at the first difference values. The ARDL bounds test and the Toda-Yamamoto causality test were used to investigate the relationship between the variables. According to the study's findings, innovations in environmental technologies have a preventive effect on global warming by lowering CO2 emissions. Additionally, no causality could be determined from innovations in environmental technologies to CO2 emissions.
