• This decision comes amid broader legal disputes over environmental regulations, which could shift under President-elect Trump, who previously revoked California's waiver in 2019

🌍 Why it matters for the planet: California’s stricter emissions rules drive the national auto market toward cleaner vehicles, as more than a dozen states follow its lead
• This accelerates progress toward reducing greenhouse gas emissions and promotes electric vehicle adoption

⏭️ What's next: The legal landscape may change with the incoming Trump administration, which could attempt to roll back California’s authority
• Meanwhile, automakers are already transitioning toward EVs, influenced by market trends and state regulations
