This study uses the Data Envelopment Analysis (DEA) slack-based model (SBM) and Malmquist Productivity Index (MPI) to evaluate energy efficiency based on CO2 emissions in 42 countries belonging to 6 continents. First, the data envelopment analysis was employed to calculate the efficiency scores for the countries individually and continent basis and then Malmquist index was used to examine the improvement. The study period chosen was 2011-2020. The results of this study showed that on the basis of continents there has been fluctuations in energy efficiency except for Australia, with an efficiency score of equal to one throughout the study period. Additionally, from the results of Malmquist Productivity Index it was found that the 42 countries showed no significant energy enhancement during the period of 2011-2020. KEYWORDS: Energy Efficiency, CO2 emissions, Continents, Data Envelopment Analysis, Malmquist Productivity Index

The goal of Government Policy on converting the utilization of kerosene to LPG is to reduce kerosene consumption and fuel oil subsidy. As kerosene has higher pollutants and greenhouse gases emissions rather than LPG, the program also has impact on reducing those emissions that would lead to improving indoor air quality. Higher energy efficiency of LPG stove and more reserve production ratio (R/P) of gas can be attributed to the advantages of utilization of LPG. Indirectly, the conversion kerosene to LPG has another impact on reducing illegal blending between gasoline or diesel with kerosene for transportation sector. The program not only has economical advantages, but also has environmental advantages.Key words: LPG, kerosene, fuel oil subsidy, energy efficiency, indoor air quality

The Cost

The Democratic Party of Japan (DPJ) came to power in 2009 promising significant transportation sector reform, but it has struggled to implement its proposals. I argue that the DPJ's initiatives faltered due to the legacy of “efficiency clientelism.” Historically, Japanese transportation policy combined two imperatives: (1) encourage efficiency by raising the cost of energy-inefficient transportation, and (2) redistribute benefits to supporters of the incumbent Liberal Democratic Party (LDP). Because of the legacy of efficiency clientelism, DPJ campaign pledges—designed to appeal broadly to the general public by reducing transportation costs—ran up against the prospect of sharp declines in revenues and energy efficiency. Efficiency clientelism was well suited to political realities in Japan prior to the 1990s, but recent developments have undercut its viability. This raises profound questions about the sustainability of Japan's energy efficiency achievements.
