Yes.

If you're into green policies, then tariffs are aligned with what you'd probably want, at least on some level. Though it's more complicated and by no means a slam dunk. One could say that producing things locally in more places is less efficient (lower economies of scale, etc.) which might result in more overhead per item, which might outweigh the extra transportation, etc. General assumption is that an unconstrained free market arrangement encourages system optimizing itself. But then there's a question what is it optimizing itself for, and that's definitely not ecological impact.

A change like that in a global economy has tons of non-linear effects, many of which it need to play over time, etc. Some changes are more easy to predict confidently, many not so much. But barely anyone argues from first principles, and its typically just tribal screeching on both sides.
