The Global Nuclear Energy Pledge gained significant momentum after several major economies joined a plan to dramatically expand nuclear power worldwide. China, Brazil, Italy, and Belgium recently announced their support for the initiative, which aims to triple global nuclear energy capacity between 2020 and 2050.
Officials introduced the Global Nuclear Energy Pledge during the COP28 climate conference two years ago. Since then, governments have increasingly backed the initiative as countries search for reliable sources of clean electricity. With the addition of four new supporters this week, the number of countries endorsing the pledge has now reached 38.
Energy ministers from the newly supporting countries confirmed their commitment during the Nuclear Energy Summit held in Paris. The meeting brought together policymakers, industry leaders, and researchers to discuss the future of nuclear power in the global energy transition.
China’s Vice Premier Zhang Guoqing described the Global Nuclear Energy Pledge as an important tool for addressing climate change and strengthening energy security. He urged countries to cooperate more closely in developing nuclear technology and expanding energy infrastructure.
Zhang also emphasized the importance of international collaboration. He argued that countries must strengthen multilateral partnerships while resisting protectionism and unilateral policy decisions that could slow progress.
China’s growing nuclear program highlights the scale of the challenge and the opportunity. Over the past fifteen years, China has added more nuclear capacity than the rest of the world combined. The country has achieved this expansion mainly through the construction of large conventional nuclear reactors.
In addition, China now aims to become a major exporter of nuclear technology. Chinese engineers have already built the Hualong One reactor abroad. Projects in Pakistan and Argentina demonstrate Beijing’s ambition to compete in the global nuclear market.
Supporters say the Global Nuclear Energy Pledge reflects a broader shift in global energy policy. Governments increasingly view nuclear power as an essential complement to renewable energy systems.
Sama Bilbao y León, head of the World Nuclear Association, welcomed the new endorsements. She said the decision by several influential economies would create strong momentum for nuclear development.
Energy analysts agree that demand for reliable electricity continues to rise. Victor Ibarra, who leads the nuclear energy program at the Clean Air Task Force, said nuclear power offers dependable, low-carbon electricity that can support modern energy systems.
He noted that geopolitical tensions and unstable oil and gas markets have exposed vulnerabilities in traditional energy supplies. Consequently, governments now look for more stable alternatives as they plan long-term energy strategies.
The Global Nuclear Energy Pledge also aligns with projections from major energy organizations. A recent report from the International Energy Agency describes a “new era of growth” for nuclear power.
The agency expects demand for electricity to increase sharply in the coming decades. Electric vehicles, large data centers, and artificial intelligence systems will require enormous amounts of reliable power.
Nuclear plants can deliver continuous electricity generation, unlike solar or wind energy, which depend on weather conditions. Therefore many policymakers believe nuclear power will play a key role in maintaining stable energy grids.
However, achieving the pledge’s ambitious targets will require enormous investment. A recent report from the World Nuclear Association suggests the goal could become achievable if governments maintain their current construction plans.
At the same time, some experts caution that the challenge remains enormous. Jacopo Buongiorno, a professor of nuclear science and engineering at the Massachusetts Institute of Technology, has warned that expanding global nuclear capacity would require a dramatic expansion of manufacturing supply chains.
He argues that reactor components, skilled labour, and specialized materials must all increase rapidly to meet the target.
Meanwhile, many emerging economies have begun leading nuclear expansion. Construction of new reactors slowed in the United States and parts of Europe over the past decade. As a result, countries such as China, India, the United Arab Emirates, and South Korea have taken the lead in building new nuclear plants.
Brazil now seeks to join this group by supporting the Global Nuclear Energy Pledge. Officials from Brazil’s foreign ministry say the country will develop nuclear energy responsibly while maintaining high safety standards.
Brazil also possesses large uranium reserves. These resources provide a potential advantage for domestic nuclear energy production. Uranium serves as the primary fuel for nuclear reactors, although it must undergo enrichment before power generation.
Despite these advantages, some analysts question whether Brazil will expand nuclear power significantly. Caio Victor Vieira from the Talanoa Institute argues that the economic benefits could remain limited.
Brazil already generates almost ninety percent of its electricity from clean energy sources, primarily hydropower. Therefore additional nuclear development may not significantly reduce emissions.
Vieira believes Brazil’s endorsement of the Global Nuclear Energy Pledge reflects strategic diplomacy rather than immediate energy needs. In his view, the government aims to support nuclear technology globally while keeping future domestic options open.
Debate over nuclear power remains particularly intense in Europe. The continent has long struggled to balance nuclear energy with renewable alternatives.
France strongly supports nuclear technology. The country generates roughly two-thirds of its electricity from nuclear reactors and promotes the technology as a reliable energy solution.
Germany, however, has taken the opposite approach. Berlin shut down its nuclear plants and invested heavily in wind and solar energy.
European Commission President Ursula von der Leyen recently reignited the debate. Speaking at the Paris summit, she described Europe’s earlier move away from nuclear power as a strategic mistake.
Von der Leyen argued that nuclear energy provides affordable and dependable electricity. She also noted that recent oil and gas disruptions in the Middle East have highlighted the risks of relying heavily on fossil fuels.
In her view, nuclear power should work alongside renewable energy systems. Renewable power remains inexpensive but intermittent, while nuclear plants provide consistent output.
However, critics remain skeptical. German Environment Minister Carsten Schneider warned that building new nuclear reactors requires enormous financial investment.
He argued that governments could invest those resources in renewable energy instead. Wind and solar power produce clean electricity without generating radioactive waste.
The Global Nuclear Energy Pledge therefore reflects both growing optimism and continuing disagreement about nuclear power’s role in future energy systems.
Nevertheless, the initiative continues to gain supporters as countries confront rising electricity demand and climate challenges. For many governments, nuclear energy now represents a crucial part of the strategy to achieve long-term energy security and reduce global carbon emissions.
