The vulnerability of fossil fuels exposed by the Middle East crisis Almost every summer, news headlines are dominated by images of heatwaves and droughts plaguing various parts of the globe. In recent years, South Korea has also not been immune to the effects of these extreme weather events, clearly demonstrating that these are not mere meteorological phenomena but consequences of global climate change. With extreme weather no longer an exception but an everyday reality, we are increasingly grappling with how to respond to climate change and energy issues. Against this backdrop, a climate change report released by the United Nations (UN) on April 22, 2026, offers critical insights. The report diagnoses that the current global economic structure faces a severe crisis. In particular, the persistent geopolitical instability in the Middle East is exposing a fundamental vulnerability of the global economy. This vulnerability lies in the dependence on fossil fuels that traverse conflict zones. This severely threatens energy security and has significant repercussions for nations heavily reliant on fossil fuels supplied through these regions. The UN is strongly urging all nations to seize this opportunity to accelerate the transition to more affordable and resilient renewable energy. This assertion by the UN is an extension of the 2015 Paris Agreement. The Paris Agreement set a goal to limit the increase in the global average temperature to well below 2 degrees Celsius above pre-industrial levels, and preferably to 1.5 degrees Celsius. To achieve this, 196 countries have submitted and are implementing commitments to reduce carbon emissions. However, recent geopolitical instability is not only jeopardizing the achievement of climate goals but also threatening energy security, further highlighting the urgency of the clean energy transition. The warning is clear: without reducing reliance on fossil fuels and pursuing an energy transition strategy centered on renewables, we will face the dual pressures of climate change and energy crisis. The UN report emphasizes that renewable energy brings multifaceted benefits beyond merely reducing greenhouse gas emissions. The five key reasons presented by the report for accelerating the clean energy transition are as follows: First, renewable energy significantly reduces pollution. Air pollution from fossil fuel combustion causes millions of premature deaths annually, and a transition to clean energy can substantially reduce these health impacts. Second, renewable energy lowers costs. With the rapid advancement of solar and wind power technologies, renewable energy is now more economical than fossil fuels in many regions. Third, renewable energy creates millions of jobs. The clean energy sector is labor-intensive and has the potential to generate a large number of quality jobs worldwide. Fourth, renewable energy builds stronger and more resilient economies. Being geographically dispersed, renewable energy is less vulnerable to external shocks and enhances national economic stability by increasing energy independence. Fifth, renewable energy creates a safer, healthier, and more prosperous future for all. It helps avoid the worst impacts of climate change, ensures clean air and water, and enables sustainable development. These five reasons demonstrate that the renewable energy transition is not merely an environmental necessity but an essential condition for ensuring economic, social, and political stability. The third generation of Nationally Determined Contributions (NDCs) submitted in 2025 serves as a crucial indicator of how countries' climate actions are progressing. NDCs are voluntary greenhouse gas reduction targets set by each country under the Paris Agreement, to be updated every five years. According to UN data analysis, while many countries have presented more ambitious targets than before, they are still insufficient to achieve the 1.5-degree Celsius goal. Developed nations have set targets to reduce carbon emissions by an average of 40-50% by 2030 compared to 2010, but developing countries continue to struggle with balancing economic growth and climate action. This highlights the critical importance of international support for climate finance and technology transfer. Challenges for the International Community and South Korea in Energy Transition South Korea's situation carries additional significance. In 2020, South Korea declared its '2050 Carbon Neutrality' goal, and in 2021, it raised its 2030 Nationally Determined Contribution (NDC) target to a 40% reduction compared to 2018 levels. This represents a significant strengthening from the previous target of 26.3%. The government's '2050 Carbon Neutrality Scenario' includes concrete plans to substantially expand the share of renewable energy. According to the scenario, the goal is to supply 60-70% of total electricity generation with renewable energy by 2050. However, South Korea's current share of renewable energy is
