Four More Countries Join Global Commitment to Triple Nuclear Energy at Paris Summit
Four additional countries have joined the global commitment to at least triple nuclear energy capacity by 2050, reinforcing growing international momentum behind nuclear power as a key solution for energy security, economic growth and climate goals.
Announced at the 2nd Nuclear Energy Summit 2026 in Paris on 10 March, the governments of Belgium, Brazil, China and Italy have endorsed the Declaration to Triple Nuclear Energy, joining a growing coalition of nations committed to expanding nuclear capacity as part of the global clean energy transition.
The Summit, hosted by the Government of France in cooperation with the International Atomic Energy Agency, brings together heads of state, international organizations, financial institutions and industry leaders to discuss the role of nuclear energy in addressing rising energy demand and achieving global climate targets.
By endorsing the declaration, these four countries join the coalition of the ambitious of 38 countries that have already committed to work together to at least triple nuclear capacity by 2050 and work together to enable policies that support the deployment of new reactors, the life extension of existing plants and the development of advanced technologies.
The Tripling Declaration, first launched at World Nuclear Symposium ahead of COP28, calls for a collective effort to triple global nuclear energy capacity by 2050 in order to help countries keep on track to meet their Paris Agreement climate goals while strengthening reliable, secure, low-carbon energy systems.
Growing global momentum
The new endorsements underscore the increasing recognition of nuclear energy’s role in delivering secure and clean electricity at scale. Nuclear energy currently provides around 9% of the world’s low-carbon electricity and plays a vital role in providing reliable baseload power to ensure grids are stable, whilst reducing reliance on fossil fuels.
Support for tripling nuclear capacity has expanded rapidly since the declaration was launched. Many of the world’s largest financial institutions, and best-known large users of energy – including Google, Amazon and Meta, have joined over 140 nuclear companies in backing the governmental declaration with their own pledges of support. Collectively, this broad coalition has signaled its backing for nuclear energy’s role in providing clean power to meet growing electricity demand.
Strengthening cooperation
Leaders at the Paris summit emphasized that meeting the goal of tripling nuclear energy by 2050 will require strong international cooperation, supportive policy frameworks and access to finance to enable the construction of new nuclear plants and the development of advanced reactor technologies.
As more countries join the declaration, the initiative continues to build a broad coalition of the ambitious committed to unlocking nuclear energy’s full potential to power economic growth, strengthen energy security and support global climate goals.
