“The assumption that economic expansion is driven by consumer demand—more consumers equals more growth—is a fundamental part of the economic theories that underlie the model. In other words, their conclusions are predetermined by their assumptions.
What the model actually tries to do is to use neoclassical economic theory to predict how much economic growth will result from various levels of population growth, and then to estimate the emissions growth that would result. Unfortunately, as Yves Smith says about financial economics, any computer model based on mainstream economic theory “rests on a seemingly rigorous foundation and elaborate math, much like astrology.”
In short, if your computer model assumes that population growth causes emissions growth, then it will tell you that fewer people will produce fewer emissions. Malthus in, Malthus out.”
