The dynamic impact of non-renewable and renewable energy on carbon dioxide emissions and ecological footprint in Indonesia

Abstract

The global trend of environmental degradation, marked by escalating carbon dioxide (CO2) emissions and expanding ecological footprints, poses a significant risk to the planet and leads to global warming. This decline in the environment is primarily attributed to the extensive use of non-renewable energy sources and substantial economic activities. This study investigates the dynamic impact of non-renewable energy (coal, gas, and oil), renewable energy, economic growth, and capital formation on CO2 emissions and the ecological footprint in Indonesia spanning from 1965–2022. Employing Fully Modified Ordinary Least Squares (FMOLS), Ordinary Least Squares (DOLS), and a robustness test with Canonical Cointegrating Regression (CCR) techniques, we seek to establish long-term associations among the studied variables. Preliminary findings, supported by our primary models, reveal that every increase in coal and gas directly results in higher CO2 emissions but does not affect ecological footprints. Conversely, every increase in oil affects the rise of ecological footprints but not CO2 emissions. Meanwhile, the rise in renewable energy will reduce both CO2 emissions and ecological footprints, consequently enhancing Indonesia's environmental quality. Furthermore, increasing economic growth will increase both CO2 emissions and ecological footprint, while the rise in capital formation reduces the ecological footprint. The Granger causality test showed unidirectional causality from CO2 emissions to renewable energy and also revealed bidirectional causality between ecological footprint and renewable energy. This study clarifies the patterns of energy emissions in Indonesia and provides policymakers with recommendations for maintaining environmental sustainability, including investing in renewable energy use and transitioning away from non-renewable energy, given the pressing climate challenges and the goal of achieving carbon neutrality.

“…Transitioning to renewables promotes mitigating environmental degradation [7,48]. The Green Solow Model (GSM) by Brock & Taylor [49] extends Solow's growth theory [50] by incorporating environmental factors.…”

“…By applying these three methods alongside our ARDL model, we aim to provide a comprehensive and robust analysis of the long-term relationships among the variables, strengthening the validity of our findings and allowing for more reliable policy implications and recommendations. This robustness test approach has also been applied by several researchers who tested their main models using FMOLS, DOLS, and CCR [3,7,61].…”

“…To preserve biodiversity, it is crucial to reduce carbon dioxide (CO2) and greenhouse gas (GHG) emissions, which are major contributors to the increasing ecological footprint and global environmental pollution [1][2][3][4][5]. Global efforts to limit temperature rise and mitigate the worst impacts of climate change require ambitious targets [6,7]. Humanity faces the challenge of achieving the new Sustainable Development Goals (SDGs), which aim to ensure access to affordable, reliable, sustainable, and modern energy for all [8,9].…”
