This study focuses on uncovering the effect of country risks and renewable energy consumption on environmental quality. In this context, the study examines Mexico, Indonesia, Nigeria, and Turkey (MINT) nations; takes economic growth, trade openness, and urbanization into account; includes data from 1990 to 2018; applies cross-sectional autoregressive distributed lag (CS-ARDL) as the main model while common correlated effects mean group (CCEMG) and augmented mean group (AMG) for robustness checks. The empirical results show that (i) economic growth, political risk, urbanization, and trade openness contribute to an increase in ecological footprint; (ii) economic and financial risks as well as renewable energy use have a positive influence on environmental quality; (iii) a unidirectional causality exists from economic risk, financial risk, political risk, economic growth, urbanization, and trade openness to the ecological footprint: (iv) the validity of the EKC hypothesis for the MINT economies is verified; (v) the robustness of CS-ARDL results are validated by CCEMG and AMG approaches. Based on these results, policymakers should promote a sustainable environment to lessen the ecological footprint. Additionally, governments should firmly support investments in green technology as well as economic and financial stability to boost energy efficiency and promote the adoption and usage of energy-saving products., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Climate change, one of the biggest threat of global life, is continuously triggered by greenhouse gases released into the atmosphere due to human activities. Carbon dioxide (CO2), one of the most important greenhouse gases, has revealed the concept of carbon footprint, and efforts to take mitigation measures by calculating it have become widespread. With sustainable campus studies, universities, where science and innovations are created, lead other institutions by creating the necessary database for measuring and managing greenhouse gas (GHG) emissions and calculating the corporate carbon footprint. This study calculated and compared the carbon footprints of Sakarya University Esentepe Campus for 2019 and 2020 when distance education was carried out during the Covid-19 pandemic. Greenhouse gas emissions resulting from activities on campus were calculated and converted to a CO2 equivalent. GHG emission factors and the Tier-1 method of the Intergovernmental Panel on Climate Change (IPCC) were used in the calculations. As a result,the carbon footprint was 13273.38 tCO2e in 2019 and 6338.72 tCO2e in 2020. It was determined that the largest share of carbon emissions was due to the use of electrical energy. The results obtained for both years were compared, and a 47.7% reduction in total emissions was evaluated. In the light of current studies on carbon emission reduction, suggestions and measures need to be taken are summarized in this research. [ABSTRACT FROM AUTHOR]

The primary aim of this paper is to provide fresh evidence by testing the linkage between renewable energy consumption, financial development, and external debts in Turkey, using the Bootstrap ARDL test (McNown et al. 2018). The Bootstrap ARDL test is desired over traditional co-integration tests due to its ability to predict when resolving power and size limitation issues, and its corresponding features, which have not been addressed by traditional co-integration tests. The ARDL testing model is employed to investigate the coefficients amongst the selected variables. The findings from the ARDL test illustrate that there is a positive linkage between renewable consumption and Turkey's financial development. Furthermore, the outcomes illustrate that the coefficient of external debt is negative and significant. The results indicate that policymakers in Turkey must use the growth of the financial sector to minimize environmental degradation by promoting investment in energy and production through renewable energy sources. Furthermore, the research suggested that Turkey's policy-makers should reformulate the external debt policy to reduce the negative influence of external debt on sustainable energy development. This could potentially be achieved by removing any restrictions on international capital flow or barriers on foreign capital and foreign investment. Hence, the findings of this paper provide valuable conclusions and recommendations for Turkey heading to sustainable and green financial sector., Competing Interests: The authors have declared that no competing interests exist.

This paper contributes to the growing literature regarding the role of Information and Communication Technologies as well as Innovation on driving the level of carbon dioxide emissions and economic growth in context of the 21st conference of the Parties to the Climate convention (COP21). Drawing the data from 13 selected G-20 countries (including Argentina, Canada, China, France, Germany, Italy, Japan, Mexico, Republic of Korea, Russian Federation, Turkey, United Kingdom, United States) during the period of 15 years, our study achieves significant results. First, only five factors impede the carbon emissions namely energy price, foreign direct investment, technology, spending on innovation and trade openness while the remainder of determinants contribute to contamination of environment, including financial development. Second, when it comes to economic growth, information and communication technological and financial development are positive driving factors. Our results do reject the absence of Environmental Kuznets Curve (EKC) from our sample. Finally, our study empirically suggests that the work of controlling consumption of oil and environmentally friendly process including manufacture-trading in these economies will limit the amount of pollution., (Copyright © 2020 Elsevier Ltd.

Maritime transportation is a major source of climate change and air pollution. Shipping emissions cause severe impacts on health and environment. These effects of emissions are emerged especially in territorial waters, inland seas, canals, straits, bays, and port regions. In this paper, exhaust gas emissions from ships in Izmir Port, which is one of the main ports in Turkey, are calculated by the ship activity-based methodology. Total emissions from ships in the port is estimated as 1923 ton y⁻¹ for NO(x), 1405 ton y⁻¹ for SO₂, 82753 ton y⁻¹ for CO₂, ton y⁻¹ for HC, and 165 ton y⁻¹ for PM in the year 2007. These emissions are classified regarding operation modes and types of ships. The results are compared with the other studies including amounts of exhaust pollutants generated by ships. According to the findings, it is clear that the ships calling the Izmir Port are important air polluting causes of the Izmir city and its surroundings.

In this paper, effect of electricity consumption, growth and trade openness on CO2 emission in Turkey between 1970-2014 was analyzed. As an econometric method, ARDL (Auto Regressive Distributed Lag Model) bounds test approach was applied. The increase in electricity consumption, GDP and trade openness by 1% increases carbon dioxide emission by 0.15%, 0.60%, 0.17%, respectively. Error correction coefficient is negative and statistically meaningful. The impact of the variables on carbon dioxide emission clearly show that measures to be taken on environmental pollution in Turkey have become mandatory. [ABSTRACT FROM AUTHOR]

Canakkale Strait (Dardanelles), is one of two straits that have Turkey with Bosphorus. This strait, which has a length of 38 miles, provides the connection of countries with a coast to the Black Sea to the Mediterranean. 43454 ships pass through the strait annually. According to 2019 data, 45.33% general cargo ship, 21.43% bulk carrier, 21.78% tanker, 6.43% container, 0.65% ro-ro, and 0.61% passenger ship, and 3.77% other type of ship passed. Therefore, by including the Canakkale 1915 bridge which will be completed in 2023, the six most frequent ship types were examined and their emission values were calculated in this study.
