No, it is not more dirty than diesel emissions. Coal plants are stationary, so they can install huge scrubbing apparatus. Diesels have to drag whatever cleanup mechanism they have installed with them, which is inherently limiting. Also, those coal plants aren't parked outside primary schools idling, and schoolkids aren't spending hours sitting around their smokestacks. Don't get me wrong: Coal is dirty as sin and radioactive as hell. Coal delenda est.
