Assessing the environmental sustainability corridor: linking oil consumption, hydro energy consumption, and ecological footprint in Turkey

Examining substitution and income effects of oil prices through the Environmental Kuznets Curve framework

This paper focuses on the decomposition of the substitution effect (SE) and income effect (IE) of oil prices within the framework of the EKC hypothesis. The objective is to analyze the contemporaneous impact of oil price shocks on other panel variables. Using panel data for G20 countries covering the period 1985-2022, the paper employs the PSVAR method for empirical analysis. Our results show that the EKC hypothesis is confirmed in G20 countries. Moreover, the SE is estimated to be negative and significant in the model where income is held constant, and oil price changes are allowed. In the model where oil prices are held constant and income changes are allowed, oil behaves as an inferior good at the beginning of economic growth. However, as economic growth progresses and income reaches a critical threshold, oil becomes a normal good. Substitution and income effects can foster sustainable growth by mitigating the environmental consequences of oil price fluctuations.

Does green innovation reduce environmental degradation? A panel threshold analysis for BRICS countries

In this present age, innovation has become inextricably tied to both long-term economic growth and environmentally sound development. In this context, the impact that environmentally focused technological advancements or innovations have on environmental quality is of the utmost importance. Therefore, the main goal of the present study is to determine how Green innovation (GI) affects environmental degradation in the BRICS countries from 1992 to 2021. The ecological footprint (EFT) is an indicator used in the study to measure environmental degradation. The study divides the components that contribute to the explanation into two categories: the GI threshold variable and the independent variables RE, GDP, and population (POP). Additionally, this study investigates the indirect impact of RE, GDP, and POP through the threshold effect of GI. The stochastic impacts of the explanatory factors are explored using sophisticated panel data estimation methods and a panel threshold model. According to the findings of the study, an improvement in environmental quality occurs when the threshold level of GI is achieved, which indicates that innovation in the form of a lower EFT is responsible for the improvement. In light of the findings, recommendations for policymakers and stakeholders in BRICS countries are to promote RE and drive GI.

Disaggregated energy consumption, industrialization, total population, and ecological footprint nexus: evidence from the world's top 10 most populous countries

High population, energy consumption, industrialization, and environmental degradation are inherently linked, making the study of ecological footprints in the most populous countries crucial for understanding their environmental impact and guiding efforts to minimize ecological degradation through sustainable resource management and conservation. Therefore, this study examines the effects of disaggregated energy consumption, industrialization, and total population on the ecological footprint of the world's top 10 most populous countries namely Bangladesh, Brazil, China, India, Indonesia, Mexico, Nigeria, Pakistan, Russia, and the USA, using data for the period of 1990-2020. The research employs Kao and Pedroni techniques of cointegration to determine whether the variables are cointegrated in the long run. The long-term equilibrium association is measured utilizing panel autoregressive distributed lag/pooled mean group (ARDL/PMG), and method of moment quantile (MMQ) regression methods. Furthermore, to test for the causal relationships between the selected variables, we used the Dumitrescu and Hurlin (D-H) panel causality method. The findings of the study reveal that renewable energy consumption, as well as GDP square, have a significant negative influence on ecological footprint, implying that renewable energy and GDP square reduce ecological footprint and thus enhance environmental quality. Furthermore, non-renewable energy, industrialization, total population, and GDP have a detrimental impact on environmental quality by increasing ecological footprint. It is also found that there is a one-way causality from non-renewable energy and industrialization to ecological footprint and a bidirectional causal relationship between ecological footprint and total population, GDP, and GDP2. Important policy implications are drawn based on the findings.

Sustainable green revolution through the development of solar power projects in Pakistan: a techno-economic analysis

Energy is essential to a recent way of life that needs to be addressed in economic and environmentally supportable improvement negotiations. The economic output of solar energy development has become the primary concern, particularly in emerging nations like Pakistan. The present research estimates a techno-economic analysis and sustainable green revolution by improving this country's solar energy projects (SEP). The study observes the moderating role of top management and risk factors of the procedures between financial management procedures and the economic output of SEP. A comprehensive opinion poll assessment accomplishes the investigation on facts from 61 respondents (finance executives, financial managers, shareholders, and owner investors). Partly least squares structural equation modeling (PLS-SEM) evaluates the hypotheses. The findings indicate that a techno-economic analysis and green revolution favor the ecological improvement of solar energy installations. The cash-flow analysis significantly contributes to the SEP's improved economic output. In addition, the results reveal that the role of top management and risk factors suggestively moderate the relationship between financial management procedures and the economic output of SEP. These outcomes give policymakers, competent authorities, and regulators an excellent guide to upsurge cleaner fabrication and ecological improvement of SEP.

Nexus between macroeconomic uncertainty, oil prices, and exports: evidence from quantile-on-quantile regression approach

International trade is key to boosting the economic growth and development of an economy. Hence, it becomes critical to analyze its determinants. The present study attempts to empirically analyze the determinants of trade exports of Pakistan with its top-5 trade partners. The prior literature suffers from biased findings due to deploying the aggregate data and ignoring the likely asymmetries in the drivers of the exports. The present study has used the monthly data of oil prices and macroeconomic uncertainty in order to empirically investigate the determinants of exports. For the purpose of analysis, several advanced econometric (quantile unit root, cointegration, and granger causality) tests and (quantile-on-quantile regression) techniques are utilized to handle the issue of asymmetries in the modeled series. The findings reveal a positive and significant relationship between oil prices in Pakistan and exports. Furthermore, macroeconomic uncertainty has a significantly negative impact on the country's exports. Based on the results, key policy implications are provided.

Role of nuclear energy in carbon mitigation to achieve United Nations net zero carbon emission: evidence from Fourier bootstrap Toda-Yamamoto

In this communication, the time series data of three major countries USA, France, and Japan from 1965 to 2020 for CO₂ emission, GDP, and nuclear energy (NE) are evaluated. It also analyzed and validated the EKC hypothesis while using nuclear energy for electricity generation. Fourier ARDL is used to investigate the hypothesis criteria, and the Fourier bootstrap Toda-Yamamoto (FBTY) causality test is used for causal linkage between the variables as well as the wavelet coherence; it is also presented the time and frequency dependency of the variables. The CO₂ mitigation by using the NE is also assessed for all three countries and assessed that the France, Japan, and USA mitigated the CO₂ per year is 0.0463 million metric ton (MMT), 0.0239 and 0.0728 MMT per year respectively. Similar to that the SO₂ is reduced by using the NE is 24.322, 43.527, and 132.592 MMT/year, and NOx is reduced by approximately 0.2847, 0.147, and 0.4478 MMT/year by France, Japan, and USA respectively by applying the NE for power generation. The evidence of the EKC, Fourier bootstrap and Toda-Yamamoto clarifies the important role of nuclear energy in terms of carbon mitigation to achieve UN net zero carbon emission by 2050. Hence, in order to meet the UN target of net zero carbon emission by 2050, the USA and Japan should increase the production of nuclear energy as France meets its 74.1% energy demand through NE by validating the EKC hypothesis; on the other hand, all the three countries should increase the production of tidal energy due to their geographical location as tides are much more predictable than wind and sun keeping in consideration to the expenses incurred and a full proof plan for disposing NE residuals in a safe place as NE residuals are highly radioactive and contains traces of thorium and uranium.

Investigating the nexus between carbonization and industrialization under Kaya's identity: findings from novel multivariate quantile on quantile regression approach

Developing nations aim to industrialize and grow sustainably often ignoring the environmental consequences. However, few empirical studies have looked at the influence of industrialization-driven economic transition on carbon footprint in developing nations using a non-parametric approach. In this milieu, on the ground of Kaya's identity and the novel multivariate quantile-on-quantile regression (QQR) (extension of Sim and Zhou's (2015) bivariate QQR model), the present research studies the impact of industrial value-added (IGVA), population, energy intensity, and carbon intensity on CO₂ emissions in India. This study is one of the first in the literature to evaluate the industrialization-carbonization nexus in the context of Kaya's identity for the Indian economy utilizing an innovative multivariate QQR approach, which makes a methodological and empirical addition to the literature. The outcomes of the multivariate QQR technique demonstrate that economic and environmental development requires continual long-run strategies. The empirical findings revealed that there is no authentication that India's carbon emissions increased due to its industrialization, which exhibited that IGVA has a negative and significant connection with CO₂ emissions. In some quantiles, population size positively impacts CO₂ emissions. On the other hand, carbonization in the Indian economy is asymmetrically affected by GDP per capita and energy and carbon intensity. The quantile Granger causality study further supported the aforementioned results. The current analysis also offers policy suggestions for environmentally friendly sustainable economic growth and to achieve the sustainable development goals (SDGs) of India.

Does political stability contribute to environmental sustainability? Evidence from the most politically stable economies

The study evaluates the effect of political risk on CO₂ emission in the top 10 most politically stable economies (Australia, Canada, Germany, Finland, Denmark, Norway, Netherlands, New Zealand, Sweden, and Switzerland) from 1991/Q1 and 2019/Q4. To the investigators' understanding, this is the first empirical analysis that inspects the effect of political risk on CO₂ emissions in the top 10 most politically stable economies. Therefore, the current paper fills a gap in the existing literature. Innovative quantile-on-quantile regression and quantile causality approaches are applied to explore this nexus. The quantile-on-quantile regression results reveal that in the majority of the quantiles, political risk enhances environmental quality for the case of Norway, Sweden, Canada, and Switzerland. Moreover, political risk degrades the quality of the environment in Australia, Germany, and Denmark, while the outcomes were mixed for the rest. Since political stability has encouraged international corporations to invest. As a result, guaranteeing political stability will attract more foreign investment, pressuring the governments of these countries to treat the climate catastrophe more urgently. Moreover, reforms should be aimed at sustaining existing environmental policies related to the green economy, while local and international firms should vigorously pursue investments in renewable energy sources and energy-saving-efficient technologies.
