Global awareness on energy security and climate change has created much interest in assessing economy-wide energy efficiency performance. A number of previous studies have contributed to evaluate energy efficiency performance using different analytical techniques among which data envelopment...

Measuring and improving the energy performance with considering emission constraints is an important issue for China’s energy conservation, pollutant emissions reduction and environment protection. This study utilizes several data envelopment analysis (DEA) based models to evaluate the...

Based on detailed national and international data on freight transportation, we analyze trends in freight CO2 emissions in 11 IEA countries from the earliest year of data availability to 2007–2010. The cross-country comparison of the freight transportation sector indicates that per capita CO2...

In Sweden, where district heating accounts for a significant share of residential heating, it has been argued that improvements in end-use energy efficiency may be counter-productive since such measures reduce the potential of energy efficient combined heat and power production. In this paper we...

This paper examines the dynamic relationship between income, energy use and carbon dioxide (CO2) emissions in Malaysia using time-series data during 1975 to 2011. This study also attempts to validate the environmental Kuznet curve (EKC) hypothesis. Applying a multivariate model of income, energy...

Electric vehicles (EVs) are considered alternatives to internal combustion engines due to their energy efficiency and contribution to CO2 mitigation. The adoption of EVs depends on consumer preferences, including cost, social status and driving habits, although it is agreed that current and...

China has proposed its 2020 clean energy target together with the climate change target of reducing CO2 intensity of the economy by 40–45% below the 2005 level. This article investigates the feasibility of these targets by testing their consistency under possible economic development...

Using energy data over the period 1981–2011 we find that US biofuels subsidies and production have provided a perverse incentive for US fossil fuel producers to increase their rate of extraction that has generated a weak green paradox. Further, in the short-run if the reduction in the CO2...

China has adopted targets for developing renewable electricity that would require expansion on an unprecedented scale. During the period from 2010 to 2020, we find that current renewable electricity targets result in significant additional renewable energy installation and a reduction in...
