John Kerry, the former U.S. Secretary of State and climate envoy, has joined Tom Steyer's investment firm, Galvanize Climate Solutions, as co-executive chair. This move follows Kerry's departure from the Biden administration in early 2024, where he advocated for global climate action for over three years. Galvanize focuses on sustainable investments and aims to drive the energy transition through innovative technologies and policies. Kerry expressed that the firm is poised to deliver competitive, commercially viable solutions in the climate sector. His recruitment raises questions about the revolving door between government and green energy industries, as he previously played a key role in shaping U.S. climate policy. With Galvanize managing around $1 billion, Kerry’s involvement is seen as a significant step in promoting climate finance and investment.
