Interlinkages of Fiscal Decentralization, Financial Development, and Carbon Emissions: The Underlying Significance of Natural Resources

Abstract

This study investigates a fresh perspective on how natural resource rents (NRR) and quantity of natural resources (QNR) modulate the influence of fiscal decentralization (FD) and the Financial Development Index (FDI) on energy efficiency (ENE) and carbon dioxide (CO2) Emissions. We draw upon the Stochastic Impacts of Regression on population, affluence, and Technology framework, taking the Brazil, Russia, India, China and South Africa (BRICS) countries as the subject of investigation from 1986-2021. Using a panel Method of Moments Quantile Regression with fixed effects, our results suggest that fiscal decentralization is favourable for environmental stability, particularly in BRICS countries with higher energy efficiency and CO2 emission levels. Increased FDI proves environmentally harmful, with pronounced effects in more energy-efficient nations. Regarding direct influences, NRR and QNR hinder energy and CO2 efficiency, notably in countries with lower energy efficiency and CO2 emissions.Regarding indirect effects, NRR and QNR positively steer the impact of fiscal decentralization and the Financial Development Index on energy efficiency and CO2 Emissions, exhibiting more potent effects in energy-efficient nations. Among other control variables, Eco-Innovation (ECO_INNO), Solar energy production (SEP), Population (POP), and Economic Growth (GDP) foster environmental stability. Fiscal decentralization should be based on a clear and responsible subnational government framework to counter rent-seeking behaviours and weak environmental conservation. Further, inclusive finance must strengthen the accessibility and cost-effectiveness of financial solutions for economic agents, promoting green consumption and investment initiatives to reach environmental stability and other Sustainable Development Goals.
