This is not how politics works. Nations are definitionally a group of people with shared interests. No one else is going to vote in the interest of the Swiss, only they will for themselves. It is absurd to equate well run, successful, wealthy nations with an obligation to harm themselves by adopting bad policies that hurt their own people. Anyone advocating for that should be ignored.

When they're responsible for not even 0.1% of global emissions you're best served targeting the countries who are the most responsible.
