What an interesting idea. Carbon footprint adjusted import\export tariffs. Community enforceable, incentivises r&d and profiteers towards low carbon FP products.

Maybe the tariffs go into some kind of refugee trust, or disaster preparedness account

I think would your proposing would be a World-Bank type action. The world bank apparently exists to use loans as leverage to get countries to change policy. That gets close to what you're after.

The problem with using the UN for this kind of action is that the UN has never imposed a tax or tariff. This would be new territory for the UN. I'm sure countries would have some problems with sovereignty. The alternative would be that all nations would act in concert to impose these tariffs.

But then if they did that, you wouldn't have a universal refugee trust. Each nation would still have control over their own finances.

Anyway, I think through the implications of what your proposing I realize why it's been so hard to get anything to change. Any kind of action requires unprecedented worldwide coordination.
