A ministerial declaration to triple nuclear energy capacity by 2050 signed by 22 countries at the Cop28 UN climate change conference in Dubai is now backed by 39 countries* across Europe, Africa, Asia, and the Americas, the London-based World Nuclear Association (WNA) said.

Six countries have joined since last year’s Cop30 in Brazil. They are Belgium, Brazil, China, Italy, South Africa and Togo.

According to the WNA, endorsing countries include eight of the world’s 10 largest economies and together account for around two-thirds of both global GDP and world energy consumption.
