As the threat of climate change grows by the day, energy transition has become a key issue across the globe. With the launch of the New Climate Regime in 2021, the parties to the Paris Agreement will be required to voluntarily set their national targets and meet their commitments in accordance with the UN Framework Convention on Climate Change. As countries push ahead with their energy policies to tackle climate change and secure a stable energy supply tailored to their domestic circumstances, the Republic of Korea is also set to make the transition towards clean and safe energy on the back of rising public concerns about safety. In June 2019, the Korean government confirmed the Third Energy Master Plan, which establishes a national energy blueprint up to the year 2040. The Third Energy Master Plan builds on the idea of a sustainable energy system stipulated in the First and Second Energy Master Plans, while also focusing on the innovative transition of the overall energy system from production and distribution to consumption. The draft was developed with great care over an eight month period by experts from academia, industry and civic groups. Following this process, the Third Energy Master Plan was finalized after an extensive collection of opinions through an online bulletin board, information sharing sessions and debates held by topics and regions as well as careful deliberation by the National Energy Committee (NEC) and the Presidential Committee on Green Growth.
