To bring down global emissions without first imposing a one-world government, we have to get each country to bring down emissions to its fair share.
The best fair first approximation to this is for each country's share to be proportional to its population. That can then be refined with some sort of emissions trading system so that countries that want to outsource high emission industries to others can provide the emissions budget to allow that work.
Anything other than a per capita first approximation requires deciding that some countries simply are not going to be allowed to develop beyond third world status.
