🗞️ Driving the news: The U.S. Environmental Protection Agency (EPA) has ruled that California cannot count emissions inspections on out-of-state trucks toward its legally required air pollution reductions, calling that part of the state’s Clean Truck Check rule unlawful

🔭 The context: California adopted the rule to reduce nitrogen oxides (NOx), a major contributor to smog, by requiring heavy-duty trucks to regularly inspect and repair pollution controls
• While EPA approved inspections for in-state registered trucks, it rejected credit for inspections on trucks registered elsewhere, citing constitutional and Clean Air Act concerns
• Out-of-state trucks account for up to 30% of California’s heavy-duty NOx emissions, largely due to port traffic

🌍 Why it matters for the planet: NOx pollution worsens air quality, harms ecosystems, and contributes indirectly to climate impacts by increasing ground-level ozone
• Blocking California from counting these reductions could slow progress toward cleaner air in one of the most polluted regions of the U.S., potentially forcing the state to pursue alternative — and possibly less efficient — emissions reduction strategies

⏭️ What’s next: California says it will continue enforcing the rule on all trucks operating in the state
• However, EPA’s decision may require additional climate and air-quality measures to meet federal standards

💬 One quote: “Extending the regulation to out-of-state vehicles serves the illegitimate objective of outsourcing the costs of attaining air quality standards,” the EPA wrote
