Because Trump would be unlikely to approve them, California has no choice but to abandon its groundbreaking rules for zero-emission trucks and cleaner locomotives.
not abandoned... just postponed for four years, because the diaperking would have shot down the requests for waivers from the feds for these anyway.
That's a huge impact. 4 years of delay means that nothing can change for 5 or 6 years
