    The relationship between China’s Airway Freight in terms of carbon-dioxide emission and export volume
    (International Economic Society, 2015) Kalayci S.; Koksal C.
    China is one of the leading economies in the world in terms of both exports and production, requiring a sophisticated logistical system. Given that transportation causes carbon-dioxide (CO2) emissions, this paper analyzes the impact of China’s Airway Freight industry on CO2 emissions through econometric models such as linear regression and the Johansen Co-integration tests, with the ultimate goal of understanding the extent of the freight industry’s influence on carbon dioxide emissions. The effect of airway freight on CO2 emissions has been especially studied between the years 1980 and 2011. © International Economic Society.

    Testing the transportation-induced environmental Kuznets curve hypothesis: Evidence from eight developed and developing countries
    (Econjournals, 2019) Ozkan T.; Yanginlar G.; Kalayci S.
    This paper focuses on the relationship between air transportation, economic growth, and carbon emissions in 8 developing and 8 developed countries during the period 1980-2013 by testing the Environmental Kuznets Curve (EKC) hypothesis. We use annual panel data from the World Bank in order to demonstrate environmental sensibility of both developed and developing countries. In this context, the research results demonstrate that environmental sensitivity is pretty low for both developed and developing countries in the period 1980-2000. Afterwards, the environmental issues of the two groups of countries are evaluated over the period from 2001 to 2013 and the research results indicate that their sensitiveness has increased remarkably, which supports the inverse-U shape of the EKC. These empirical results are also consistent with the Kyoto protocol’s political aims and goals. In addition, based on the Johansen co-integration test results, there is a long-term stable relationship between as air transportation, CO2 emissions, energy use, and gross domestic product for both developed and developing countries, with the exception of Colombia and Turkey. © 2018, Econjournals.
