California’s leadership on reducing truck pollution has been on full display the past few years, passing critical regulations requiring 90 percent reduction in smog-forming nitrogen oxide (NO X ) emissions from diesel trucks and requiring manufacturers sell an increasing share of electric trucks to move away from fossil fuels altogether.
