Catalyzing a new
nuclear energy ecosystem

Enabling the rapid expansion of safe and secure nuclear energy to
help satisfy growing global demand for reliable, cost-effective,
carbon-free heat and power.

About The Initiative

About

Collaborating for a
sustainable future

The Nuclear Scaling Initiative (NSI) is a collaborative effort of Clean Air Task Force, the EFI Foundation, and the Nuclear Threat Initiative to build a new nuclear energy ecosystem that can quickly and economically scale to 50+ gigawatts of safe and secure nuclear energy globally per year by the 2030s.

NSI’s plan for revolutionizing how nuclear energy is constructed, financed, and regulated will advance climate goals, spark economic development, expand energy access, and ensure that nuclear technology is used for only peaceful purposes.

Our mission

Enable the rapid expansion of safe and secure nuclear energy to help satisfy growing global demand for reliable, cost-effective, carbon-free heat and power.

Our vision

A world where nuclear energy propels progress toward climate, energy security, and economic development goals without leading to more nuclear weapons.

    Where does NSI’s funding come from?

    NSI is hard at work implementing our global strategy for scaling nuclear energy thanks to a foundational gift from Joe Gebbia and Isabelle Boemeke. They also initiated a $5 million matching challenge to catalyze additional philanthropic support, which the Quadrature Climate Foundation and other generous donors have already contributed toward. NSI is actively seeking additional donors for the challenge; please contact Adam Wagner ([email protected]) to learn more.
