What factors cause ocean CO2? A panel data analysis.

Over the past three decades, industrial innovations and technological advancements have changed business dynamics, adversely devastating the overall environment. As a result, our oceans have been severely affected due to climate change and global warming. To address this issue, this study investigates the factors that cause ocean CO2 using a sample of 44 countries over 2012-2021 and explores a dynamic and causal relationship between economic growth, ocean carbon dioxide emissions, energy consumption, and control variables relating to the ocean industry. This study finds that increasing economic activity tends to increase ocean carbon emissions. The results support the evidence of the environmental Kuznets curve (EKC) hypothesis suggesting an inverted U-shaped association between ocean emissions and real income for the sample countries. Moreover, this study reports that ocean health index, maritime container transport, trade of fishery and ocean species, aquaculture production and marine species, and employment rate in the fishery processing sector are the significant factors of ocean CO2. Region-wise analyses suggest that real income positively influences ocean emissions and confirm the evidence of the EKC hypothesis in European sample countries but these relationships have an insignificant effect in Asia and the Pacific and the American regions. Furthermore, a short-run unidirectional panel causality flows from the production of aquaculture and other species to RD&D, from OHI and GDP to trade of fishery and other species, and from OHI to employment rate in the fishery sector. Likewise, bidirectional causality runs from energy consumption and maritime transport to ocean CO2 in the long term. Regarding the long-run causal association, the results determine that all of the estimated coefficients of the lagged error correction terms are statistically significant which explains that they are crucial in the adjustment process as they deviate from the long-run equilibrium.

Exploring the dynamic relationship between financial development, renewable energy, and carbon emissions: A new evidence from belt and road countries.

This empirical study examines the endogenous relationship between carbon emissions (CO2), financial development, renewable energy, globalization, and institutional quality in 64 belt and road initiative countries (BRI) using a two-step system generalized method of moments (GMM) approach with panel data over the period 2003 to 2018. Furthermore, this study used (Dumitrescu & Hurlin, 2012) causality test to estimate the variables' causal relationship. The results indicate that financial development significantly increases CO2 emissions and causes environmental degradation in BRI countries. However, renewable energy and globalization mitigate CO2 emissions and improve the quality of the environment. Institutional quality was positive in correlation with CO2 emission and indicates bad governance, corruption, weak bureaucracy, and improper implementation of environmental laws cause environmental degradation. Further, the study also reports a bidirectional relationship of financial development, renewable energy, and institutional quality with CO2 emissions and a unidirectional causality running from globalization to CO2 emissions in BRI countries. This study offers policymakers insight into restructuring the financial system, energy consumption pattern, and global integration and improving institutions' quality for a sustainable environment and the economy at the national and regional levels.
