> So that local companies that have to pay for their pollution are not at a structural disadvantage against companies in other parts of the world where they can pollute for free.
Nobody should assume that there are local producers with sufficient capacity for all tariffed items, or that foreign production is polluting more per item made. China has the most installed renewable power, ahead of everybody else by far, I'm pretty sure they pollute less per item produced.
In other words, yours is not a valid purpose, what I've said before is. The EU is a customs union among other things, meaning there are already tariffs in place for "structural disadvantages" which include more than just pollution, itemizing them would require new watchdogs to measure the alleged offenses on a country by country basis. And for what? Is it at all possible? And who'd watch the watchers?
> Why are they not a tool for preventing pollution? And what is haphazard about this application?
I explained that above. It's only an excuse for taxing the population and more inflation. It has to be reiterated that these tariffs are a tax on the population, not on foreign businesses. If you don't know what tools are used for increasing business efficiency, you should study econ harder. Ditto if you don't know why I'm talking about efficiency.
> Not a productive comment for this website.
You mean, you've got the power to decide what's productive here and what not. Is that power limited to this website only or it applies to others too? I'm not saying you don't have the power, but your naked, argument-free claim on it doesn't provide any useful information.
