Disaggregated energy consumption, industrialization, total population, and ecological footprint nexus: evidence from the world's top 10 most populous countries.

High population, energy consumption, industrialization, and environmental degradation are inherently linked, making the study of ecological footprints in the most populous countries crucial for understanding their environmental impact and guiding efforts to minimize ecological degradation through sustainable resource management and conservation. Therefore, this study examines the effects of disaggregated energy consumption, industrialization, and total population on the ecological footprint of the world's top 10 most populous countries namely Bangladesh, Brazil, China, India, Indonesia, Mexico, Nigeria, Pakistan, Russia, and the USA, using data for the period of 1990-2020. The research employs Kao and Pedroni techniques of cointegration to determine whether the variables are cointegrated in the long run. The long-term equilibrium association is measured utilizing panel autoregressive distributed lag/pooled mean group (ARDL/PMG), and method of moment quantile (MMQ) regression methods. Furthermore, to test for the causal relationships between the selected variables, we used the Dumitrescu and Hurlin (D-H) panel causality method. The findings of the study reveal that renewable energy consumption, as well as GDP square, have a significant negative influence on ecological footprint, implying that renewable energy and GDP square reduce ecological footprint and thus enhance environmental quality. Furthermore, non-renewable energy, industrialization, total population, and GDP have a detrimental impact on environmental quality by increasing ecological footprint. It is also found that there is a one-way causality from non-renewable energy and industrialization to ecological footprint and a bidirectional causal relationship between ecological footprint and total population, GDP, and GDP. Important policy implications are drawn based on the findings.
