Abstract

Climate change is a global concern driven by increasing pollution through rising CO2 emissions and growing ecological footprint from human activities. This research investigates how environmental quality (proxied by CO2 emissions and ecological footprint) in Indonesia is affected by multiple factors, including natural disasters, fossil fuels, renewable energy consumption, economic growth, and capital formation from 1965 to 2022. The analysis employs the Autoregressive Distributed Lag (ARDL) model, with robustness ensured using Dynamic Ordinary Least Squares (DOLS), followed by Granger causality tests to examine dynamic relationships between variables. The findings show that natural disasters, fossil fuel consumption, and economic growth contribute to increasing CO2 emissions in the long run, while renewable energy consumption helps reduce them. Natural disasters exhibit a negative but insignificant impact on the ecological footprint. Economic growth increases the ecological footprint, whereas capital formation helps reduce it in the long run. In the short run, fossil fuels are found to increase CO2 emissions, while renewable energy reduces them. Natural disasters are found to increase the ecological footprint. Additionally, the Granger causality test confirms a unidirectional relationship from both natural disasters and economic growth to environmental quality. This study recommends that Indonesia implement integrated strategies focused on accelerating green energy adoption and enhancing disaster resilience to achieve environmental quality.

Abstract

The energy transition from fossil fuels to renewable energy is underway to achieve a sustainable society based on carbon neutrality. However, there is an ongoing debate about how the implementation of such energy technologies will affect sustainability (social, economic, and environmental aspects). This review outlines research trends on the effects of renewable energy deployment on sustainability from the perspectives of income inequality, energy inequality, human capital, energy education, gender, health, and community, focusing on high-profile papers for the period 2014-2024. Renewable energy and income inequality are negatively related, and promoting renewable energy innovation through R&D subsidies is expected to decarbonize and alleviate poverty. Human capital promotes decarbonization through the diffusion and consumption of renewable energy, but in some cases, the effects are not apparent. However, energy education can be effective in addressing human capital shortages in the renewable energy sector. Gender inequality and energy inequality are closely linked, with women with poor energy access suffering health problems due to smoke pollution from cooking. Women's participation in society will encourage the spread of renewable energy and improve health standards. Local communities with voluntary citizen participation, rather than state initiative, are expected to be the actors that encourage decarbonization through renewable energy.
