Newsom Criticizes Trump and Highlights California's Climate Leadership at COP30

California, led by Gov. Gavin Newsom, is participating in the UN climate conference in Brazil to project its climate leadership and influence global climate policies, despite lacking formal international negotiating power. The trip aims to foster international relationships, promote state policies, and position Newsom as a global climate leader, possibly for a future presidential run, amid criticism over its cost, effectiveness, and the broader impact of such international engagements.
