    Analysis of the relationship between tourism, green technological innovation and environmental quality in the top 15 most visited countries: evidence from method of moments quantile regression

    Global warming, climate change and environmental pollution are considered among the important developments that threaten all world economies. In this context, the transition to a zero-emission economy remains one of the environmental sustainability goals of policymakers. The literature investigating the tourism-environmental pollution relationship has limited emphasis on the role of green technological innovation. Therefore, this study explores the effect of tourism and green technological innovation on CO2 emissions in top 15 most visited countries during the period of 1995-2019. Renewable energy consumption, financial development and economic growth are integrated into the CO2 emissions equation as control variables. The cointegration tests verify the existence of a cointegration between variables. The long-run estimaters reveal that tourism, green technological innovation and renewable energy consumption serve to improve environmental quality by reducing CO2 emissions. Contrary to these findings, financial development and economic growth play a role in the increase of CO2 emissions implying a deterioration in environmental quality. The bootstrap causality analysis points to a bidirectional causality between tourism and CO2 emissions and between green technological innovation and CO2 emissions. The findings will make important contributions to policy makers in these countries in meeting their CO2 emissions reduction targets. Graphical AbstractThe long-run findings

    Nexus between technological innovation and environmental pollution in selected OECD countries
    (Wiley, 2024) Cetin, Murat; Ozturk, Ilhan; Sarigul, Sevgi Sumerli; Murshed, Muntasir; Kilavuz, Emine
    Addressing environmental pollution is fundamental to establishing sustainable development across the globe. While navigating the Fourth Industrial Revolution, it is of critical relevance for economies worldwide to come up with innovative measures that can withstand the factors driving environmental pollution. On that note, this study explores the technological innovation-environmental pollution linkages in the context of 10 members of the Organization for Economic Cooperation and Development (OECD) using data spanning from 1994 to 2018. Notably, considering ecological footprints as the environmental proxy, the analysis controls for the corresponding levels of economic growth, financial development, and renewable energy consumption in the concerned countries. In addition, the long-term estimates are investigated using Augmented Mean Group, Common Correlation Effects Mean Group, Fully Modified Ordinary Least Square, and Dynamic Ordinary Least Square techniques while the causality relationship is determined by Dumitrescu-Hurlin panel bootstrapped causality test. The results establish the long-term cointegrating linkages among the variables considered. It is also observed that economic growth increases the ecological footprint level, while technological innovation, renewable energy consumption, and financial development reduce it. Moreover, the results reveal that technological innovation and ecological footprint causally influence each other, while there are one-way causalities moving from economic growth and financial development to ecological footprint. Furthermore, a two-way causality concerning renewable energy consumption and ecological footprint is also detected. Considering these results, it is pertinent for the selected OECD countries to improve energy efficiency rates, scale investment for developing the renewable energy sector, and execute policies that support investments in initiatives concerning low-carbon technological development. Additionally, these countries should look to implement policies that are compatible with the objectives of establishing green growth so that low-emission development can take place to tackle climate change-related problems.
