The pledge is nonbinding, but highlights the growing support for expanding nuclear power among leading industries, finance and governments.

Major companies such as Amazon and Google on Wednesday signed a pledge to support the goal of at least tripling the world's nuclear energy capacity by 2050, on the sidelines of the CERAWeek conference in Houston.

Amazon, Google and Meta have joined a call by big, energy-intensive companies for governments and utilities to build more nuclear power in the latest boost to the industry’s revival. Oil group Occidental and chemical producer Dow are also among the eight large buyers of energy to sign a pledge to support the goal of tripling nuclear capacity by 2050.
