Pathways to Carbon Neutrality: The Role of Environmental Governance, Environmental Technology, Renewable Energy Transition, and Economic Policy Uncertainty in Africa
研究了1990-2022年五个非洲国家中环境治理、环境技术、可再生能源转型和经济政策不确定性对碳中和目标的影响，发现可再生能源转型有助于实现碳中和，而其他因素则起阻碍作用。
ABSTRACT As climate change and environmental deterioration continue to escalate due to substantial CO 2 emissions, nations worldwide are implementing approaches to alleviate CO 2 emissions and accomplish carbon neutrality (CNE) goals. The current study examined CNE objectives for five selected nations in Africa, spanning from 1990 to 2022. This paper assessed the effects of economic policy uncertainty (EPU), renewable energy transition (RET), environmental technology (ENT), and environmental governance (ENG) on CNE. The paper employed the Fully Modified OLS (FMOLS), DOLS, as well as the Fixed Effects regressions. The findings of the paper show that RET assists in enhancing the CNE objectives in the chosen five African countries. Furthermore, the paper's results show that ENG, ENT, and environmental policy uncertainties are disruptive to CNE progress. Accordingly, the pairwise Granger causality outcomes indicated a unidirectional causality between ENG, ENT, and CNE, whereas there exists a bidirectional causality between EPU, RET, and CNE. Lastly, this research offers policymakers, governments, and stakeholders with valuable recommendations and insights for fostering resilience and ecological quality in the understudied African region.
