Decomposition factors.

Variables	Construction	Series	Measurement
c-effect	CO2E/FEI	Carbonization factor	Fossil fuel energy used in electricity generation (Emissions per unit of fossil fuel energy used in electricity generation).
e-effect	FEI/FEG	Transformation factor	The inverse expression of the efficiency in the conversion of inputs of fossil fuel into electricity.
s-effect	FEG/TEG	Fossil fuel intensity factor	Share of the electricity of fossil origin in the total electricity generated in the system.
w-effect	TEG/GDP	Electricity intensity factor	The electricity intensity of economic activity (Efficiency factor in the use of electrical power by economic agents).
y-effect	GDP	Production factor	Production obtained by the economic system which is a proxy of “scale”. The variations in GDP would determine the path that emissions (production) would follow (Sun, 1999)
