Worse depends on what you're talking about. They emit more particulates which are hazardous, though they do have filters to mitigate that somewhat. In terms of impact on warming, no they're not worse than gas vehicles. They mostly emit nitrogen oxide, which while not great for the environment, has much less of an impact on climate change compared to carbon (not to be confused with nitrous oxide which has a significant warming potential).
