IAEA at COP30: Nuclear Energy, Technology and Science Shaping a Sustainable Future
Belém, Brazil – November 7, 2025 – The International Atomic Energy Agency (IAEA) is set to play a pivotal role at the 30th United Nations Climate Change Conference (COP30), spotlighting innovative nuclear solutions that address global energy and environmental challenges. The conference, taking place in Belém, Brazil from November 10 to 22, 2025, will feature a robust program presented by the IAEA to demonstrate how nuclear technology and science contribute to a sustainable future.
Atoms4Climate Pavilion: A Hub for Innovation and Collaboration
For the fourth consecutive year, the IAEA will host the Atoms4Climate Pavilion at COP30. This dedicated space serves as an interactive hub for nuclear information, featuring exhibits that illustrate how nuclear science and techniques support clean energy development, enhance food security, promote sustainable water management, and protect ocean ecosystems. Throughout the conference, IAEA experts will engage with attendees, offering presentations and participating in high-level discussions and events.
The pavilion will be inaugurated on November 10, with a virtual address delivered by IAEA Director General Rafael Mariano Grossi. The opening ceremony will also include keynote speeches from ministers, senior government officials, representatives of international organizations, industry leaders, and non-governmental organizations, all underscoring the critical role of nuclear energy in advancing the clean energy transition.
Highlighting Nuclear Energy’s Role in Climate Action
IAEA’s presence at COP30 underscores nuclear energy’s potential to support global decarbonization goals. The agency will lead a key side event under the United Nations Framework Convention on Climate Change (UNFCCC), focusing on innovative financing strategies to accelerate the deployment of low-carbon energy sources. Building upon insights from the first Global Stocktake at COP28, the discussion aims to map pathways for scaling up nuclear power alongside renewable energy sources, and to integrate emissions abatement and removal technologies—particularly in sectors where reducing carbon emissions remains challenging.
A special emphasis will be placed on the rapid deployment of small modular reactors (SMRs). These emerging nuclear technologies offer flexible, cost-effective power solutions tailored for smaller electrical grids and are well suited for energy-intensive industries, data centers, and commercial shipping. An IAEA-led session will explore policies, regulatory frameworks, and financing mechanisms that can facilitate the adoption of SMRs worldwide.
Further advancing nuclear innovation, the IAEA, in collaboration with ITER, will present updates on fusion research and technology development—shedding light on the potential future contributions of fusion energy in the global clean energy mix.
Nuclear Science Driving Environmental Solutions
Beyond energy, the IAEA will highlight a suite of cutting-edge nuclear techniques that bolster environmental sustainability and resilience. Several events will showcase how nuclear technologies strengthen food security, ensure sustainable water resource management, and protect ocean health.
A notable presentation will cover the sterile insect technique, an environmentally friendly nuclear-based method used to control agricultural pests such as fruit flies. Drawing on successful experiences from Latin American countries, this method not only supports sustainable agriculture but also secures international market access for fresh produce.
Another event will focus on the application of nuclear and isotopic techniques to monitor glacier retreat—providing essential data for maintaining water resources amid the impacts of climate change.
Additionally, attention will be given to nuclear methods that reveal the potential of blue carbon ecosystems (such as coastal wetlands and mangroves) in sequestering carbon, preserving marine biodiversity, and sustaining coastal economies. These insights assist policymakers in crafting strategies to protect these vital natural assets.
Promoting International Collaboration and Partnerships
The IAEA’s engagement at COP30 emphasizes the importance of international collaboration and public-private partnerships in advancing nuclear technologies and applications. Through initiatives such as Atoms4NetZero, the agency supports emerging and developing economies in deploying nuclear solutions that align with climate goals and sustainable development.
