CO2 emission depends on four causal factors: Population (P); Output per capita (O) : $GDP per capita; Energy intensity (E) : energy consumed per $ of GDP; Carbon intensity (C) : the amount of CO2 emitted per unit of energy produced. The EIA calls them Kaya factors as they are multiplicative (on an indexed basis):
P x O x E x C = CO2 emission
