- Major corporations including Amazon, Google, and Meta signed the Large Energy Users Pledge at CERAWeek 2025, committing to tripling global nuclear energy capacity by 2050 to meet rising energy demand and climate goals.
- Companies highlighted nuclear power’s unique ability to deliver reliable, carbon-free, around-the-clock energy, essential for data centers, AI infrastructure, and industrial operations.
- The pledge signals growing corporate momentum behind nuclear energy as a cornerstone of global decarbonization, energy security, and sustainable growth.
At CERAWeek 2025 in Houston, Texas, a powerful coalition of major energy-consuming companies—including Amazon, Google, Meta, Dow, Occidental, Allseas, and OSGE—publicly committed to supporting the tripling of global nuclear energy capacity by 2050. This initiative, known as the Large Energy Users Pledge, adds significant momentum to a growing international movement that has already seen endorsements from 31 countries, over 140 nuclear industry companies, and 14 of the world’s leading banks and financial institutions. Held annually, CERAWeek brings together energy executives, policymakers, and innovators to address critical issues and opportunities shaping the global energy future. This year, nuclear energy took center stage.
The pledge reflects a shared understanding that global energy demand is projected to rise substantially in the coming decades, driven by economic growth and the expanding digital economy, despite ongoing efficiency improvements. In response, the signatories recognize nuclear power as a key solution for achieving a clean, reliable, and resilient energy future. Unlike variable renewable sources such as solar and wind, nuclear energy can generate electricity consistently, regardless of weather or time of day. This makes it particularly attractive to large energy users who require stable, around-the-clock power to support data centers, industrial operations, and other critical infrastructure.
Several company executives emphasized how nuclear energy aligns with their long-term sustainability goals and operational needs. Lucia Tian, Head of Clean Energy & Decarbonization Technologies at Google, expressed pride in backing the pledge and highlighted nuclear’s pivotal role in securing a sustainable energy future. Brandon Oyer, Head of Americas Energy and Water at Amazon Web Services, underscored the urgency of accelerating nuclear development to meet future energy demands and address climate change, noting Amazon’s $1 billion investment in nuclear technologies over the past year. Similarly, Urvi Parekh, Head of Global Energy at Meta, pointed to the importance of nuclear power in meeting growing energy demand while ensuring grid reliability and low-carbon energy delivery.
Corporate interest in nuclear energy has been growing rapidly, particularly as companies look to reduce carbon emissions while scaling up operations. The increasing energy intensity of artificial intelligence infrastructure and data centers has made nuclear power—especially advanced designs like small modular reactors—an increasingly viable solution. Beyond electricity, nuclear energy also has the potential to decarbonize industrial processes through the production of clean hydrogen, process heat, and synthetic fuels, as well as provide heating for urban areas.
The Large Energy Users Pledge was initially launched by the World Nuclear Association in collaboration with the Emirates Nuclear Energy Corporation ahead of COP28 in Dubai in 2023. It now serves as a rallying point for stakeholders across the energy sector, finance, and industry to prioritize nuclear development as part of the global clean energy transition. With nuclear currently supplying about 9% of the world’s electricity through 439 operable reactors, and energy demand expected to grow at approximately 4% annually according to the International Energy Agency, the need for scalable, dependable, and carbon-free power sources has become increasingly urgent.
The pledge will be formally unveiled during a special CERAWeek event co-hosted by the World Nuclear Association and Urenoc. This milestone reflects a significant shift in how large-scale energy consumers view nuclear energy—not just as an option, but as a necessity for meeting future energy and climate goals.
