It is rich nations that are the problem.
For any given limit we wish to hold on warming, there is a total acceptable amount of CO2 emissions we can allow for the world.
Once emitted, CO2 stays in the atmosphere for a few hundred to a thousand years. Rich nations have emitted more than their fair share for a couple hundred years--that's a large part of how they got rich. Of the CO2 now in the atmosphere, over 60% came from North America and Europe and 47% from the US and the EU+UK.
Emitting more than your fair share to get rich is fine, if:
1. Once rich you use part of that wealth to switch to low or zero emissions, and
2. Either do something to take the CO2 you emitted out of the atmosphere so that there is room in the global CO2 budget for someone else to become rich the same way, or help them become rich by subsidizing them so they can skip the high emissions stage and go straight to the low/zero emissions rich stage.
The current rich nations aren't doing well on either of these.
