The nexus between green finance and energy consumption in regional comprehensive economic partnership countries

Green finance has been valued and promoted by Regional Comprehensive Economic Partnership (RCEP) countries for its attribute of supporting green and sustainable development. However, the fossil fuel-centric growth pattern poses a threat to the sustainable development of RCEP countries. The existing literature remains inadequate regarding the relationship between green finance and fossil energy consumption. An in-depth understanding and empirical examination of the nexus between green finance development and fossil energy consumption in RCEP countries is key to successful policymaking and sustainable development. This study proposes a theoretical framework for analyzing the nexus between green finance and fossil energy consumption. Then, a green finance development index is constructed by using the entropy weight method based on green credits, green securities, and green investments. By utilizing method of moment quantile regression (MMQR), panel data of 10 RCEP countries from 2008 to 2020 are investigated. The results demonstrate a strong nonlinear pattern of green finance's impact on reducing fossil energy consumption. Conventional finance and fossil energy consumption from the preceding period significantly promote fossil energy consumption, while green technology serves as a mitigating factor for fossil energy consumption. However, the impacts of education and environmental expenditure on fossil energy consumption are limited and inconsistent. Hence, the relevant practitioners, including governments and policymakers, are encouraged to collaboratively promote the green finance policies, and devise tailor-made strategies based on countries' features. Additionally, this study recommends that the RCEP countries incorporate research and development of green technologies, as well as environmental and educational expenditures, into the policymaking process.
