My takeaway as always is that clearly the single most impactful thing most people can do is not have children, or have fewer children. Unless you're a billionaire, nothing in your life with have close to the same impact as not reproducing.
I would however also point out that simply divided total emissions reductions needed vs all humans is misleading. The average Nigerian emits FAR less CO2 than the average Indian. The average Indian emits less than the average Chinese person, who emits less than the average American.
If we look at per country per capita emissions [1], we can see that Africa, South America and Asia (excluding China and India) have current emissions below the 2C warming. So yes, they don't need to reduce anything at the country level - simply not increase.

North America and Europe on the other hand...

Yup. Stop reproducing below replacement rate. Embrace GMOs. Consume less. That's the only viable path we have.
