Certainly buying a brand-new EV (from any company) isn't making a positive impact on the environment. But, writ large, switching from ICE to electric cars is a giant step in the right direction. So I think it's safe to call that one a wash. Most people buying a new EV would have been buying a new ICE car anyway, and it is much better to further the electrification of transportation. Even if taking public transportation--a sacrifice--would be more helpful.
