The 11th IEEJ/APERC International Energy Symposium
-Advancing Realistic Energy Policies for Addressing the Energy Trilemma-

　The global energy landscape is increasing structural complexity on both the demand and supply sides. Rapid economic growth in emerging economies, expanding electrification, and the surge in electricity consumption fueled by generative AI are accelerating energy demand growth. At the same time, heightened geopolitical risks are increasing supply-side uncertainty. These developments are reshaping the traditional assumptions that once underpinned energy policy. Although renewable energy deployment is accelerating and the importance of nuclear power is revisited, significant challenges remain—ranging from system-wide market and regulatory design to cost reduction and integration of variable renewable electricity into the power system.

　While the international community continues to uphold ambitious climate goals, the gap between those ambitions and energy realities is widening. Global energy transition discourses are increasingly shifting from an ideology-driven focus on greenhouse gas emissions reduction toward a more pragmatic perspective that incorporates cost, reliability, and security. Achieving a balance among energy security, economic viability, and environmental sustainability—the so-called “energy trilemma”—has become an unavoidable and urgent policy challenge for countries around the world.

　Against this backdrop, the symposium aims to articulate realistic and actionable pathways for addressing the energy trilemma. Through discussions with leading experts from Japan and overseas, we will explore the issue from the following three perspectives.

　　✓　Key Drivers Behind Rising Energy Demand
　　✓　Expectations and Challenges for Further Expanding Decarbonized Power Sources
　　✓　The Gap Between Climate Ambitions and Energy Realities

　11：45-13：00　Lunch Break

＜PM＞

13:00-14:30 Session 2 “Expectations and Challenges for Further Expanding Decarbonized Power Sources” This session will examine the current status and challenges related to nuclear power and renewable energy, which are central to expanding decarbonized power sources. In addition, the session will focus on “integration cost,” which is becoming increasingly important in evaluating renewable energy deployment, and analyze components and level of the cost.
	Presentation (15min/person ×3 persons), Panel Discussion & Q&A (45min) Presenter and Panelist： Dr. Sama Bilbao y Leon, Director General, World Nuclear Association (WNA) Mr. Dato Ir. Ts.

14:30-15:00	Coffee Break
15:00-16:30　 Session 3 “The Gap Between Climate Ambitions and Energy Realities” This session will discuss how the widening gap between international climate ambitions and the realities of the energy sector should be assessed. Building on this understanding, the session will delve into the formulation of sustainable climate goals and examine the significance of establishing targets that reflect these evolving realities.
	Presentation (15min/person ×3 persons), Panel Discussion & Q&A (45min) Presenter and Panelist： Dr. Laura Cozzi, Director of Sustainability, Technology and Outlooks, International Energy Agency Dr. Hoesung Lee, President of Carbon Free Alliance and a Special Ambassador for Carbon Free Energy, Republic of Korea/ Chair of the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment (2015–2023)/ Distinguished Fellows, IEEJ Toshiyuki Sakamoto, Board Member, Director for Climate Change and Energy Efficiency Unit, IEEJ Moderator: 　Ichiro Kutani, Senior Research Director, Manager, Global Energy Group 1, Director, Energy Security Unit, IEEJ
