Global nuclear energy capacity should at least triple by 2050 to achieve climate targets, while still delivering the energy security our world requires.

The new Net Zero Nuclear website shows how scaling nuclear energy up to deliver the increasing demand for clean, reliable electricity requires energy leaders, financing houses and communities to mobilize quickly and efficiently.

The articles below outlines how nuclear energy is helping reduce emissions today, and how it can contribute to a sustainable net zero emissions future.

It includes information on last year's COP27 climate change conference, which took place at Sharm el Sheikh, Egypt.
