IAEA Showcases Nuclear Energy and Science as Key Drivers for a Sustainable Future at COP30
Belém, Brazil – November 7, 2025
The International Atomic Energy Agency (IAEA) is set to play a prominent role at the 30th United Nations Climate Change Conference (COP30), scheduled to take place from November 10 to 22, 2025, in Belém, Brazil. Leveraging its expertise in nuclear technology and science, the IAEA will highlight nuclear energy’s vital contribution to tackling global energy demands and environmental challenges amid the ongoing clean energy transition.
Atoms4Climate Pavilion: A Hub for Innovation and Collaboration
Continuing its tradition for the fourth consecutive year, the IAEA will host the Atoms4Climate Pavilion at COP30. This dedicated venue serves as a vibrant hub for disseminating nuclear knowledge, hosting events, and fostering networking among international stakeholders. Attendees can explore interactive exhibits illustrating how nuclear science supports clean energy development, food security, sustainable water management, and ocean conservation efforts worldwide.
IAEA specialists will be available throughout the conference to engage with visitors, answer inquiries, and participate in high-level discussions, underlining nuclear technology’s role in combating climate change and advancing the United Nations Sustainable Development Goals (SDGs).
The pavilion’s opening ceremony on November 10 will feature a virtual keynote address by IAEA Director General Rafael Mariano Grossi, alongside remarks from ministers, senior government officials, industry leaders, and representatives of international organizations and NGOs.
Highlighting Nuclear Energy’s Expanding Role in Climate Action
Among the key focuses at COP30 will be the accelerating deployment of nuclear power as part of integrated clean energy strategies. Building on progress from COP28’s Global Stocktake, the IAEA will lead a special event under the UN Framework Convention on Climate Change (UNFCCC) to discuss innovative financing approaches for expanding low-carbon energy sources. This includes strategies to enhance collaboration between nuclear power, renewable energy, carbon abatement, and carbon removal technologies.
A significant spotlight will be on Small Modular Reactors (SMRs), which offer flexible, scalable, and cost-effective energy solutions suited for small grids, energy-intensive industries, data centers, and maritime transport. An IAEA session will delve into policy frameworks, regulatory considerations, and financing models that can expedite SMR adoption globally.
Further advancing the frontier of nuclear research, the agency will co-host a session with the ITER fusion project to present the latest developments and future prospects in nuclear fusion technology.
Additional discussions will explore novel financial mechanisms under the IAEA’s Atoms4NetZero initiative, which aids emerging markets and developing economies in integrating nuclear power within their energy planning and climate mitigation efforts.
Nuclear Science Driving Solutions Beyond Energy
Beyond power generation, the IAEA will spotlight pioneering nuclear applications that enhance environmental sustainability. Events will feature cutting-edge nuclear techniques supporting food security by improving pest control through the sterile insect technique—an environmentally friendly method successfully implemented in Latin America to combat fruit fly infestations, thereby safeguarding agricultural exports and promoting sustainable farming.
Other sessions will focus on nuclear methods for monitoring glacier retreat, which is crucial for preserving sustainable freshwater reserves amid climate change. The agency will also showcase how nuclear and isotopic technologies help quantify the carbon sequestration potential of "blue carbon" ecosystems, emphasizing the conservation of coastal biodiversity and marine resources.
Engaging the Global Community
The IAEA’s involvement at COP30 reiterates the pivotal role that nuclear energy, technology, and science play in fostering a sustainable future. Through international cooperation and public-private partnerships, the agency aims to catalyze innovative policies and technologies that address the multifaceted challenges of climate change.
