South Korea has ranked at the bottom of standings among members of the Organization for Economic Cooperation and Development(OECD) in terms of the ability to provide sustainable energy. 

According to the World Energy Council’s Energy Trilemma Index report released on Friday, South Korea came in 30th among the OECD’s 37 member states.  

The index ranks 128 countries' energy systems across three dimensions: energy security, energy equity and the environmental sustainability of energy systems. 

Though South Korea saw its ranking among the 128 surveyed countries jump six notches from last year to 31st, its ranking among OECD members climbed just one notch to 30th this year.  

The report said that among the Group of 20 nations, which are responsible for almost 80 percent of global greenhouse gas emissions, South Korea, Japan and Russia were the weakest performers in terms of environmental sustainability.  

The report said, “South Korea and Russia have made little progress in shifting their energy mix away from fossil fuels over the last decade, despite the remarkable declines in the cost of renewables.” 

The report was quick to add, however, that Asian countries, including South Korea, present “dramatic improvements in sustainability, with governments investing in transition to clean energy, and increasing private competition and incentives in the renewable sector.”
