A DEA Approach for Assessing the Energy, Environmental and Economic Performance of Top 20 Industrial Countries

Abstract

Due to growing concerns of global warming, reducing carbon emissions has become one of the major tasks for developing countries to meet the national demand for energy policies. The objective of this study is to measure the energy consumption, carbon emission and economic-environmental efficiency in terms of the environmental performance of the top 20 industrial countries by employing a data envelopment analysis (DEA) model from 2013 to 2017. This study used the trilemma of energy efficiency, CO2 emission efficiency, and environmental efficiency, and also the contribution included the quantitative analysis of 20 industrial countries The results show that the energy efficiency of Australia, China, Japan, Saudi Arabia, and Poland are the best performing countries, whereas Mexico, Indonesia, Russia, and Brazil are identified as least efficient among all 20 countries. Furthermore, Russia’s energy intensity has a maximum score while Poland has a minimum score. Additionally, in the case of CO2 emission efficiency, Brazil, France, and Saudi Arabia are considered as efficient while nine country’s scores were less than 0.5. The results show that most countries exhibit higher performance in economic efficiency than environmental efficiency. The study provides valuable information for energy policy-makers.

RETRACTED ARTICLE: COVID-19 and stock exchange return variation: empirical evidences from econometric estimation

“…The documentary has been examined from two angles: (1) the transmission instability during the COVID-19 crisis and (2) the relationship between the COVID-19 indicators and stock market performance and economic uncertainty. We examined recent publications on the economic and financial effects of the COVID-19 pandemic (Iqbal et al 2019a ). Several new publications looked at COVID-19’s financial and socioeconomic consequences (Tlemsani et al 2020 ).…”

RETRACTED ARTICLE: It is time to control the worst: testing COVID-19 outbreak, energy consumption and CO2 emission

“…First is the effect of COVID-19 on the energy sector in determining energy consumption pattern from the raw material of production (oil demand, supply and consumption) to end-product (electricity and end mean of fuel used in the travel and transport industry). Second, how the energy market will reshape a shift and recover after a pandemic or, in other words, how energy market will revive after a pandemic is the most important question of recent times that need answer (Igwe 2020). Endorsing the previous literature, a recent study is extending the theoretical contribution by testing these missing links between the COVID-19 outbreak, energy consumption and CO 2 emission.…”

Assessing Supply Chain Performance from the Perspective of Pakistan’s Manufacturing Industry Through Social Sustainability

“…Through the case study process, based on stakeholder awareness, Ikram et al [52] identified organizations' management, occupational safety and health management, wages, labor rights, education and training, labor relations, children and slavery, organizational commitment, worker welfare, research and development, altruism, stakeholders, product liability, and social issues in the Pakistani Industry and their role in the SSSCM. It is also believed that true statements of sustainable development practices for stakeholders and consumers tend to take a gradual approach and expand consideration of the business sector [53,54].…”
