Determinants of CO2 emissions in the MERCOSUR: the role of economic growth, and renewable and non-renewable energy

Abstract

The main objective of this study was to analyze the impact of energy consumption (divided into renewable and non-renewable sources) and income on CO emissions within the environmental Kuznets curve (EKC) model for the Southern Common Market (MERCOSUR). To do so, the annual panel data collected during the 1990-2014 periods was used. The CO variable, representing carbon dioxide emissions in metric tons per capita, was used as a proxy for the emission of pollutants. The annual data were obtained from the World Bank (World Development Indicators). The sample consisted of the five MERCOSUR member countries: Argentina, Brazil, Paraguay, Uruguay, and Venezuela, comprising a period of 25 consecutive years. The results showed that energy consumption from renewable sources had a negative impact on CO emissions, while the energy consumption from non-renewable sources had a positive impact. The positive impact of economic development on CO emissions was also seen. In addition, this study supports the validity of the EKC hypothesis for the MERCOSUR because GDP (real output) leads to environmental degradation while GDP reduces the level of gas emissions.

Determinants of material footprint in BRICS countries: an empirical analysis

“…Similarly, some of the papers which discussed the linkages between renewable energy, natural resources, urbanization, and environmental quality in BRICS economies are (Sebri & Ben-Salha, 2014;Zakarya et al, 2015;Wu et al, 2015;Adedoyin et al, 2020;Azevedo et al, 2018;Nathaniel et al, 2020b). There are many studies has investigated in different countries like Sub-saharan countries (Inglesi-Lotz & Dogan, 2018), for Turkey (Pata, 2018); for Latin American and Caribbean countries (Nathaniel et al, 2020a); for Europe (Al-Mulali et al, 2015;de Souza et al 2018); for Pakistan (Alam et al, 2007;Shaheen et al, 2020;Ali et al, 2020;Hassan et al, 2019), for India Alam et al 2019).…”

The Impact of Nonlinear Fiscal Decentralization, Green Energy, and Policy Uncertainty on Sustainable Environment? A New Perspective From Ecological Footprint in Five OECD Countries

“…Scholars recently have introduced several factors that can contribute to a sustainable environment; which include fiscal decentralization (H. Chen et al, 2018;Hao et al, 2020;Ji et al, 2021;Shi et al, 2018), green energy (Adams et al, 2020;Charfeddine & Kahia, 2019;de Souza et al, 2018;Majeed & Luni, 2019;Öztürk et al, 2020;Rasoulinezhad & Saboori, 2018;Riti & Shu, 2016), and reducing economic policy uncertainty (Adedoyin & Zakari, 2020;Anser et al, 2021;Pirgaip & Dinçergök, 2020;Ulucak & Khan, 2020;Yu et al, 2021) as an important factor to preserve our planet and thereby creating a sustainable environment.…”

“…The gradual shift from non-renewable to renewable energy solutions leads to continuous improvement in environmental sustainability. Thus to promote renewable energy and ecofriendly energy consumption is need of the hour to achieve economic-cum-environmental goals and objectives (Charfeddine & Kahia, 2019;de Souza et al, 2018;Lau et al, 2018;Ridzuan et al, 2020;Riti & Shu, 2016;Samuel Asumadu Sarkodie et al, 2020;Sharif et al, 2019;K. Zhang et al, 2017).…”

Calidad ambiental y crecimiento económico: análisis dinámico para América Latina y el Caribe

“…En los últimos años se observa un considerable esfuerzo por entender la relación entre las emisiones de dióxido de carbono (co 2 ) y el crecimiento económico. La emisión de co 2 tiene un papel central en el debate actual acerca del desarrollo sustentable, directamente relacionado con el consumo de energía (Nguyen & Kakinaka, 2018;De Souza et al, 2018); y a su vez, el crecimiento económico se relaciona positivamente con un mayor nivel de consumo de energía. Por otro lado, es razonable pensar que el uso eficiente de los recursos energéticos requiera de un mayor crecimiento económico (Koengkan & Fuinhas, 2020;Rodríguez-Caballero & Ventosa-Santaularia, 2017;Antonakakis et al, 2017;Ito, 2017).…”
