PurposeThe purpose of this paper is to examine the impacts of (non-renewable and renewable) energy consumption and trade on environmental pollution in an environmental Kuznets curve (EKC) setting in Turkey for the 1965–2016 period.Design/methodology/approachBesides conventionally used unit root tests, Zivot–Andrews unit-root test is also employed to account for a possible structural break. To investigate the interrelationships among the variables, the autoregressive distributed lag and the vector error correction methodologies are employed.FindingsThe results verify the EKC hypothesis. Moreover, increases in trade and non-renewable energy consumption rise carbon emissions in long run, while renewable energy consumption reduces it in both short- and long-run. The causality analysis reveals that there are bi-directional long-run causalities between non-renewable energy consumption and carbon dioxide emissions, and between trade and carbon dioxide emissions. Additionally, the neutrality hypothesis is valid for the renewable energy consumption-income nexus in both short- and long-run. For the non-renewable energy consumption-income nexus, the neutrality hypothesis holds only in short-run and the conservation hypothesis holds only in long-run.Originality/valueThis is the first study which incorporates both renewable energy consumption and trade into its environmental pollution model for Turkey. Moreover, by investigating short- and long-run causalities among the employed variables, more robust policy implications are put forward. Lastly, this study employs a longer sample period and considers a structural break in its models.

Abstract Green growth means promote economic development and growth, while certify that natural assets continue to provide the resources and ecological. This research analyzes that how green growth is affected by technological innovation for South Asia (Bangladesh, Pakistan, India, Sri Lanka, and Nepal) economies during 1990 to 2019. Basic econometric tests such as Cross-section dependence test, Panel unit root tests and Wester Lund co-integration test is applied. Furthermore, we use the FMOLS and DOLS models for estimating the impact of CO2 emissions on patent by resident, renewable energy consumption, foreign direct investment, and GDP per capita. The results of all panel unit root tests reveal that all the variables are stationary at a 1st difference. Westerlund panel co-integration test confirmed the long-run relationship. In both the FMOLS and DOLS models, the findings show that patent application by residents and renewable energy consumption have negative and statistically significant impacts on CO2 emissions. While GDP has positive and statistically significant effect on CO2 emissions and FDI has no effect on CO2 emissions in both the long run and short run. The results recommend that government needs to take sustainable energy related source, for instance, renewable energy consumption which are beneficial to ecosystem as it increases green economy.

Purpose: A level of education may change the energy consumption habits of people. Further, economic growth may also demand cleaner energy consumption for better environmental quality. This research explores the impacts of education and economic growth on the renewable energy consumption of Saudi Arabia. Methodology: This research utilizes the unit root test of Dickey & Fuller (1981), cointegration test of Pesaran et al. (2001), and bound testing values of Kripfganz & Schneider (2020). Main Findings: Income and secondary education increase Renewable Energy Consumption (REC) in the long and short run. Primary education reduces REC in the long run, and the lag of primary education has a positive effect on REC. Implication: This research recommends to increase the level of education to promote renewable energy consumption for a cleaner environment. Novelty: Educational level and renewable energy consumption nexus have not been investigated in Saudi Arabia. Therefore, we claim an empirical contribution.

Private Partnership

Environmental sustainability is an important issue for current scholars and policymakers in the East Asian and Pacific region. The causal and long-run effects of technological innovation, public–private partnership investment in energy, and renewable energy consumption on environmental sustainability in the East Asian and Pacific regions have not been comprehensively explored while taking into account the role of economic growth using quarterly data for the period 1992–2015. Therefore, the present study aims to close this literature gap using econometric approaches, namely Bayer–Hanck cointegration, autoregressive distributed lag (ARDL), dynamic ordinary least square (DOLS), and fully modified ordinary least square (FMOLS) tests. Furthermore, the study utilizes the frequency domain causality test to capture the causal impact of public–private partnership investment in energy, renewable energy consumption, technological innovation, and economic growth on CO2 emissions. The advantage of the frequency domain causality test is that it can capture the causality between short-term, medium-term, and long-term variables. The outcomes of the ARDL, FMOLS and DOLS show that renewable energy consumption and technological innovation mitigate CO2 emissions, while public–private partnership investment in energy and economic growth increase CO2 emissions. Moreover, the frequency causality test outcomes reveal that technological innovation, public–private partnership investment in energy, and renewable energy consumption cause CO2 emissions, particularly in the long-term. Thus, as a policy recommendation, the present study recommends promoting renewable energy consumption by focusing more on technological innovation in the East Asia and Pacific regions.
