Yes, the entire world cannot buy larger cars than what we need them for, we cannot fly around the world on vacations, we cannot throw away half the food we produce, we cannot buy clothes to use them once, and so on.

Such needless things, often more related to consumption culture than living standards, is responsible for a large portion of emissions.

Not only that, but we live in societies with an enormous capital in infrastructure built up from previous emissions.

I think westerners should at least start thinking about not emitting CO2 just for the fun of it, before telling others to not have too many children.
