They are not worse for the environment than ICE vehicles. This is total FUD nonsense that is significantly fueled by right wing and auto astroturf campaigns. Their lifecycle emissions are vastly lower. It's so mundanely bad a talking point that even low-level sources like factcheck.org publish informers on it. Don't spread misinformation.
EVs aren't good for the environment. They're less bad. Auto-dominant culture remains a non-starter for longterm sustainability, both fiscal and environmental, for most communities around the world.
There are some situations where BEVs are maybe worse overall than ICE counterparts. Rail and busses, for example, where the BEV just makes no sense (put up a pantograph or third rail for a huge LCCA discount and massively lower emissions). Cargo trucking may also fall in this camp; trucks simply cannot be that heavy on modern asphalt design. But for regular passenger vehicles there is no question.
