Sahin Macit, Nazife
This study analytically assesses the climate change and environmental sustainability performance of G20 countries using data from the 2024 Climate Change Performance Index (CCPI) and Environmental Performance Index (EPI) reports. The analysis employs Sum-Weighted Information (SWI) and Ranking Alternatives with Weights of Criterion (RAWEC), which are Logarithmic Decomposition of Criteria Importance (LODECI)-based multi-criteria decision-making (MCDM) methods. The study created three separate decision matrices, taking into account the CCPI and EPI criteria individually, as well as their combination. The criterion weights were determined using the LODECI method; greenhouse gas emissions, climate policy, and air quality were the most significant criteria. The results show that China and Saudi Arabia demonstrate strong environmental performance in CCPI-based rankings, while Germany, the United Kingdom and France demonstrate strong performance in EPIbased evaluations. In the integrated analysis, Germany ranked first using both methods. The consistency of the rankings obtained using the SWI and RAWEC methods was high, which supports the reliability of the analyses. However, some differences in ranking were observed depending on the method used, the distribution of criteria and the country sample. Overall, the study emphasizes the pivotal role of methodological diversity and data-driven approaches in multidimensional environmental assessments for policy-making, while demonstrating the robustness of the findings through sensitivity and comparative analyses.

Purpose: Motivated by the criticality of transportations system in tourism activities, this study further uncovers the effect of the main transportation modes arising from inbound tourism activities on the ecological footprint across the panel of selected coastline Mediterranean countries (CMC). Design/methodology/approach: The study considers a suitable econometric approach for the case of CMC with the dataset that covers the period 1998–2022. Findings: While the result reveals that all the modes of transportation except air deteriorate environmental sustainability by increasing ecological footprint in the long run, higher impact of environmental woe is associated with the land transportation. Similarly, the findings further show that economic expansion and conventional energy utilization in the examined panel and in each country spurs ecological footprint, thus worsening environmental quality. Meanwhile, for the country-specific observations, ecological footprint is (1) mitigated by tourism activities associated with air, water and land transports in Spain, (2) triggered by tourism activities associated with land transport in Croatia and (3) spurred by land transport in Italy. Originality/value: Policy inference from these results suggests the need to scale up the adoption of a low-emission transportation system in the countries.

The need for transportation is increasing with the effect of globalization in the developing economic system. The transportation sector, which is essential for economic development, may pose some threats to a sustainable environment. Although European countries have achieved various successes in reducing carbon emissions, they are struggling to reduce carbon dioxide (CO2) emissions from transportation. To overcome this difficulty, European countries are using various policy instruments such as environmental taxes. In this context, this study investigated the impact of disaggregated environmental taxes (pollution, energy, and transport), structural change, and institutional quality on transport-related carbon emissions (water, air, and road transport) in 24 European countries over the period 2008-2022. To this end, the study uses the novel half-panel jackknife estimation and the bias-corrected method of moments. The results indicate that there is no long-term relationship between environmental taxes and water transportation-related CO2 emissions. In contrast, structural changes and pollution taxes are effective in reducing road and air transport-related CO2 emissions. These results suggest that European countries should focus on reducing CO2 emissions through effective pollution taxes and encourage carbon taxes instead of energy and transport taxes, thereby supporting the European Green Deal's goal of becoming the first climate-neutral continent.
