Nuclear Energy

We, the G7 Ministers of Energy, recognize the need for enhancing global energy security and meeting rising energy demands – including those driven by electrification, digitalization, and artificial intelligence.

Those countries that opt to use nuclear energy, or to support its use, are committed to advancing research, development, and deployment of innovative nuclear technologies, including small modular reactors and advanced reactors. This includes sharing national best practices, facilitating access to financing tools, promoting clear, safe and efficient licensing approaches, and reinforcing coordination on commercial projects among G7 members and with partner countries. This also includes recognition of nuclear energy as a non-emitting baseload energy source consistent with national priorities and international commitments.

1. In this context, we are committed to upholding the highest standards of nuclear safety, security, and non-proliferation, recognizing these as fundamental pillars for the peaceful use of nuclear energy. We emphasize the critical role of the International Atomic Energy Agency (IAEA), as well as independent nuclear safety authorities, in maintaining rigorous standards and securing public trust.
2. In line with our commitment to responsible approaches to nuclear energy, we endorse identifying high-level principles for responsible nuclear waste management, including collaborative community-based siting processes to advance robust, long-term solutions. We will continue to collaborate on this through relevant multilateral initiatives such as those being advanced under the OECD’s Nuclear Energy Agency and the IAEA.
3. Reflecting our shared interest in energy security and reliability, we will continue to cooperate on nuclear supply chains, prioritizing resiliency and reducing dependence on unreliable partners. Efforts will focus on securing nuclear fuel supply chains and enhancing collaboration amongst G7 partners and other multilateral fora.
4. Those countries that opt to use nuclear energy recognize the importance of creating enabling conditions for nuclear deployment and encourage continued dialogue with like-minded partners on establishing favourable conditions – including policy, regulatory, and other measures – and commercial partnerships. This will support the rapid, safe, secure, and stable expansion and operation of nuclear facilities.
5. Those countries that opt to use nuclear energy also encourage dialogue on supporting responsible deployment in third countries, including through enhanced cooperation among their Export Credit Agencies, multilateral development banks, and other international financial institutions.
6. Building on this, those countries that opt to use nuclear energy support developing conducive business environments that are enabled by balanced regulatory approaches and more responsive permitting processes, without compromising safety, as well as enhanced workforce development through targeted training programs and promoting engagement from international financial institutions in nuclear energy projects.
7. We encourage innovation in new and emerging nuclear technologies, including for those countries that opt to use it, for powering energy-intensive digital infrastructure, strengthening resilient energy systems and supporting critical services, where appropriate.

Fusion Energy

1. We recognize that, in the future, fusion energy has the potential to make a significant contribution to meeting the growing demand for energy. Acknowledging global advancements and investment in fusion energy technology, we underscore the importance of sustained international collaboration on fusion energy with trusted partners, encouraging private investments and public engagement. We take note of Canada’s initiative in continuing the G7 Working Group on Fusion Energy in September 2025, launched under the Italian G7 Presidency, providing a platform for exchanging progress updates and strengthening cooperation.
2. Looking ahead, we emphasize the continued necessity of sharing best practices, cooperation amongst trusted fusion-relevant Research and Development centres and harmonization of standards as well as consistent approaches to fusion regulations as appropriate, which would enable the deployment of fusion energy technologies. Furthermore, we emphasize the importance of exchange between the G7 member states regarding the respective regulatory frameworks and technical standards for fusion facilities and their further developments. This group encourages the IAEA to have a continuing role in facilitating discussions that will enable development of proportionate fusion safety standards that can be incorporated into designs for first-of-a-kind fusion energy facilities.

We welcome the endorsement of the G7 Statement on Nuclear and Fusion Energy by the Republic of Korea and Ukraine.
