I see only two solutions:

* A global carbon tax/cap/trading/limit system, with sanctions for any country that does not comply.

* A realistic risk that a global compulsory carbon cap/tax/trading system will be implemented, and that any carbon emissions tracking will be backdated - such that any extra emissions today might disadvantage your country in the future.

With neither of the above two, it is in every countries best interests to emit as much carbon as possible and use free/cheap carbon based energy to produce goods/food/whatever, while doing only a few highly visible environmental moves.



How often do these economic sanctions actually work? From my limited perspective they seem to only hurt the poor, whilst the rich find loophole after loophole and are largely unaffected.


It's magical thinking, and it's proven to be so over and over and over again. It's "Why don't we [ambiguous collective] just..." as public policy.
