Impact of coal rents, transportation, electricity consumption, and economic globalization on ecological footprint in the USA

Abstract

Over the last three decades, the world has been facing the phenomenon of the ecological deficit as the ecological footprint is continuously rising due to the persistent decline of the per-capita bio-capacity. Moreover, there is a substantial increase in globalization and electricity consumption for the same period, and transportation is contributing to economic prosperity at the cost of environmental sustainability. Understanding the determinants of ecological footprint is thus critical for suggesting appropriate policies for environmental sustainability. As a result, this study analyzes the impacts of economic globalization, transportation, coal rents, and electricity consumption in ecological footprint in the context of the USA over the period 1995 to 2018. The data have been extracted from “Global Footprint Network,” “Swiss Economic Institute,” and “World Development Indicators.” The current study has also applied the flexible Fourier form nonlinear unit root test to examine the stationarity among variables. For the empirical estimation, a novel technique, the “quantile auto-regressive distributive lag model,” is applied in the study to deal with the nonlinear associations of the variables and to evaluate the long-term stability of variables across quantiles. The study’s findings indicate that coal rents, transportation, and globalization significantly and positively contribute to the deterioration of ecological footprints at different quantile ranges in the short and long run. Electricity consumption is found to have a positive and significant impact at lower quantile ranges in the long run but not have a significant impact in the short run. The study suggested that lowering the dependence of the transport sector on fossil fuels, more use of hydroelectricity, and stringent strategies to curb coal consumption would be helpful to reduce the positive influence of these variables on ecological footprints in the USA.

The Role of Sustainable Energy, Technology Adoption, and Green Finance on the Environmental Sustainability in China

“…The results showed that technology adoption has a positive link with ES. These results are supported by Nathaniel, Yalçiner, and Bekun (2021); (Shah, Hussain, Nawaz, & Iqbal, 2021;Wenlong et al, 2022), which claims that the tendency of firms to adopt new technologies enables them to address and mitigate environmental issues and sustains environmental productivity. These results are also in line with the study of Jimoh and Lin (2019).…”

“…The findings proposed that a) wind power had the lowest energy consumption, less emission of carbon, and lowest possible environmental effect, b) according to an examination of ecological footprints at the provincial level, whilst the other provinces were in ecological surplus, with the majority of them having ecological areas above 50%, c) Of the three RE sources, only wind power reduced energy consumption as compared to thermal power generation, which used 1170.911 kJ/kWh. Currently, the most effective source of RE is wind power (Wenlong et al, 2022). Similarly, Apergis and Payne (2014) also worked on RE output along with ED through carbon emission.…”

Integrating non-renewable energy consumption, geopolitical risks, economic development with the ecological intensity of wellbeing: evidence from quantile regression analysis

“…However, it will not be helpful during the later stages. Wenlong et al (2023) used the ARDL approach. They discovered that coal transportation and rents both considerably and favorably contribute to the shortand long-term decline of ecological footprints at various quantile ranges.…”

Investigating the Impact of Green Natural Resources and Green Activities on Ecological Footprint: A Perspective of Saudi Vision 2030

“…In comparison, rare studies employed the ecological footprint as a proxy for the environmental deterioration. Analyzing ecological footprint variables has become crucial for establishing environmental sustainability [37]. The effects of human activity on ecosystems have persistently worried academics over the years.…”
