Newsom is the most prominent US politician at Cop31, a process the Trump administration continues to boycott
The leader of the world’s fourth biggest economy, California governor Gavin Newsom, has explicitly endorsed a global phase out of the fossil fuels that drive climate breakdown.
Newsom told the Guardian that California is “100%” behind the efforts of the so-called Santa Marta coalition, a group of more than 50 countries that includes many of the world’s largest economies, to transition away from oil, gas and coal toward solar, wind, batteries and other non-carbon energy sources.
