Linking green transportation and technology, and environmental taxes for transport carbon emissions

Climate change and global warming pose severe environmental challenges globally, with transportation and industrialization significantly contributing to CO2 emissions. This study investigates the interplay between green transport initiatives, environmental taxes, and CO2 emissions in energy transition countries from 1990 to 2020. Utilizing the Method of Moments Quantile Regression (MMQR), Fully Modified Ordinary Least Squares (FMOLS), and Feasible Generalized Least Squares (FGLS), the study reveals that environmental taxes (ETax) and green transport (GT) are strongly negatively correlated with CO2 emissions. These results underscore the potential of increasing environmental taxes and advancing green transportation technologies as effective strategies for mitigating environmental degradation. This study highlights that improvements in energy efficiency and renewable energy adoption further contribute to reducing CO2 emissions, while globalization (GI) also plays a role in decreasing emissions. This research adds to the existing literature by providing robust empirical evidence on the effectiveness of green policies and sustainable practices in reducing CO2 emissions, thereby offering policy recommendations for governments to enhance green transportation and promote environmental sustainability in the long term.
