    Do patents, renewable energies and energy taxes in the transport sector reduce transportation carbon emissions in the European Union?
    (Taylor & Francis Inc, 2024) Pata, Ugur Korkut; Erdogan, Sinan; Pata, Selin Karlilar; Kartal, Mustafa Tevfik
    Transportation infrastructure plays a significant role in exacerbating climate change as it contributes to a substantial increase in carbon dioxide (CO2) emissions. The sole economic sector in which European countries have not succeeded in reducing greenhouse gas (GHG)emissions is the transportation industry. Therefore, reducing transport-related emissions is a primary focus of emphasis in the European Union's efforts to meet its climate targets. Accordingly, this study analyzes the impact of renewable energy use, patent development, and energy taxes in the transport sector on the three different modes of transport-related emissions (aviation, road, and rail) in the 10 highest-income countries of the European Union over the period 2008-2020. The study uses the novel half-panel jackknife estimator for this analysis. The results of the estimation show that patents contribute to the reduction of CO2 emissions in aviation and rail transportation, while renewable energies are only effective in rail transportation. In the context of road transportation, energy taxes are effective in mitigating CO2 emissions. Based on these findings, it is recommended that European Union policymakers promote the use of electric vehicles and eco- friendly means of transportation in road transport through energy taxes, increase the use of renewable energy sources such as biodiesel in rail transport, and reduce CO2 emissions by supporting patents that promote green innovations in the aviation sector.

    Identifying the influence of climate policy uncertainty and oil prices on modern renewable energies: novel evidence from the United States
    (Springer, 2024) Pata, Selin Karlilar; Balcilar, Mehmet
    The policy uncertainty surrounding climate change can intensify the urgency of implementing climate policies and influence investment decisions, thereby serving as a catalyst for policy transformation. In this context, given its withdrawal from and subsequent re-commitment to the Paris Agreement, the United States (US) may experience policy uncertainty over climate change. Given this backdrop, it is of paramount importance to explore how the uncertainties caused by shifts in climate policy affect clean energy. This study delves into the impact of climate policy uncertainty and oil prices on modern renewable energy sources, such as solar, wind, geothermal, and biofuels. The most recent monthly data from 1989 to 2023 are used by conducting the Residual Augmented Least Squares (RALS) methodology. The empirical findings show that the uncertainty surrounding climate policy is leading to a shift in the US energy composition, with a focus on solar energy, wind energy, and biofuels. Moreover, the fluctuation in oil prices has a significant effect on the deployment of wind and biofuels, but no discernible effect on solar power. These findings provide significant insights for aligning climate policy in the US with Sustainable Development Goal (SDG) 7, highlighting the crucial importance of encouraging investments in solar energy, wind energy, and biofuels.

    Navigating the role of transport and energy taxes on carbon neutrality in Poland: A Fourier-based approach
    (Sage Publications Ltd, 2024) Pata, Selin Karlilar; Erdogan, Sinan; Kartal, Mustafa Tevfik; Pata, Ugur Korkut
    As part of the Green Deal, European countries have set themselves the target of halving carbon emissions by 2050. Environmental taxes are a powerful tool of environmental regulations to minimize carbon emissions, and they can play a significant role in ecological development. Poland is one of the countries that generates the most environmental tax revenues among European countries. In this context, the study analyzes the impact of energy and transport taxes on carbon emissions for Poland within the framework of the environmental Kuznets curve (EKC). Accordingly, the study applies the Fourier autoregressive distributed lag approach to the data for the period 1995/Q1-2022/Q4. The results demonstrate that (i) the EKC hypothesis is valid for Poland, (ii) energy taxes support carbon neutrality targets, and (iii) transport taxes have no impact on carbon emissions. Compatible with the results, the study suggests that the Polish government should prioritize energy taxes over transport taxes and expand them to minimize carbon emissions.
