The per capita emissions of USA/Canada/Gulf countries have to be cut by a factor of 8-10 to reach sustainable levels. The per capita emissions of EU/China/SEA have to cut by 4 to reach sustainable levels. All within the next 25 years if we want to avoid crossing tipping points.

Halving the population in 50 years is not a realistic plan.

Here are some projections to support that statement. Supposedly 2084 is peak population.

I haven't read up on all the assumptions made for those projections. If something unassumed pops up that makes things substantially worse then the population peak would come earlier I guess. But that's a gamble.
