If we reduce population growth by 1% in the world economy, we can have growth in income per capita at a level of about 7% and still hold carbon emissions unchanged. Namely, by reducing population growth, we can permit growth in income per capita without polluting planet earth more than otherwise. So this is very important because it suggests to us that policies that target gender equality, the diffusion of contraceptive methods, and the rewards of education are policies that could mitigate population growth and ultimately permit the growth of income per capita without the liability of greater carbon emissions.
