Assessment of financial development on environmental degradation in KSA: how technology effect?

Financial development and environmental quality in developed countries: a systematic literature review

Studying the effect of financial development on environmental quality has become imperative in the modern world due to the climate change challenges. Hence, this systematic literature review provides a comprehensive overview of the existing body of knowledge on the nexus of financial development and environmental quality in developed countries. Three databases: Web of Science, Scopus, and Google Scholar were used to search the relevant articles in this domain. Finally, 20 journal articles qualified for the systematic literature review based on the pre-defined article inclusion criteria as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) framework. We found that a range of econometric approaches were used in all examined papers, employing a diverse range of proxy variables to model the relationship between financial development and environmental quality. Overall, the findings of the examined papers imply mixed evidence of this nexus in developed countries. We highlight the knowledge gap in this research domain examining the financial development and environmental quality link from different proxies.

Carbon neutrality challenges in Belt and Road countries: what factors can contribute to CO2 emissions mitigation?

As climate warming is intensifying, CO2 emission reduction has aroused the great attention of many governments and scholars. Compared with traditional industrial times, the influencing system of CO2 emission in modern society has taken great changes due to technological advancement, improvement in energy efficiency, and the popularity of the internet. But the current literature has not reached a consensus on this theme. Our study tends to investigate the nexus between international trade, international trade taxes, energy intensity, internet usage, renewable energy, and CO2 emission while incorporating income levels by using the data from Belt and Road countries in the 2008-2020 period. For this purpose, we applied the unit root test, CSD, Granger causality test, AMG, CCMG, and CS-ARDL methods. The results show that energy efficiency, GDP, and internet use have significantly negative effects on CO2 emission, while GDP has significant positive impacts on CO2 emission. By classifying 65 countries along Belt and Road into four groups of low-income level, low-middle income level, upper-middle income level, and a high-income level, the regional heterogeneities of influencing factors of CO2 emission is confirmed. Furthermore, this empirical study provides new insights to policymakers to reduce CO2 emissions through technology innovation, international cooperation, and human capital investment without deteriorating economic growth.

Are globalization, urbanization, and energy consumption cause carbon emissions in SAARC region? New evidence from CS-ARDL approach

This study examines the impact of energy consumption, urbanization, and globalization on environmental degradation proxied by carbon emissions (CO₂) in the South Asian Association for Regional Cooperation (SAARC) countries, namely Sri Lanka, Pakistan, Maldives, Nepal, Bhutan, Bangladesh, and India using data over the period 1990-2018. The cross-sectional autoregressive distributed lag (CS-ARDL), pooled mean group (PMG), and Dumitrescu and Hurlin (D-H) Granger causality techniques are employed for the empirical analysis. First and second-generation panel unit root tests are used to determine the stationary level of all data series which reveals mixed order of integration. The empirical findings show that urbanization, gross domestic product (GDP) per capita income, energy consumption, industrial growth, globalization, and financial development cause CO₂ emissions, while the other variables, namely arable land and innovation, put negative effects on CO₂ emissions. Moreover, the D-H heterogeneous test results exhibit that bi-directional relationship exists between CO₂ and arable land, urbanization, industrial growth, and financial development, while a unidirectional causality exists between CO₂ emissions and GDP per head income. These findings suggest that planned urbanization, investment in renewable energy sources, and effective strategies regarding the economic and financial integration with the global economies are required for a clean and green environment.
