Besides the tariff on imported products the sibling talks about, you can also rebate the tax paid on exported products.
It's not simple to manage those adjustments, but governments deal with much more complex taxes everywhere. It's not a big deal.
And yeah, the UBI cancellation of the tax, the tariffs on imported products and the rebate on exported products deal with every single problem I've seen people post about a carbon tax, except for "expensive gasoline will destroy our economy!", that is almost always pushed by people that live in a place with some of the cheapest gasoline prices of the world.
There is an add-on that some people push where you don't cancel all of the tax in an UBI, but use a part of it to finance carbon capture projects. I do really like this one, but it's not something that is required for things to work.
