Just wanted to clarify what the parameters
aeei were in FUND, and how they are calculated? I am guessing that
acei is growth rate of (carbon) emissions intensity, and
aeei is growth rate of energy intensity?
However, if so, it is my understanding that carbon emissions intensity is usually calculated as (CO2 emissions / GDP), whereas the following code (from scenconverter.jl in FUND) suggests that carbon intensity is calculated based off energy intensity, which is in turn calculated as (energy use / income):
v.energint[t, r] = p.energuse[t, r] / p.income[t,r] v.emissint[t, r] = p.emission[t, r] / p.energuse[t, r] if !is_first(t) v.scenaeei[t, r] = -(v.energint[t, r] / v.energint[t - 1, r] - 1.) * 100. v.scenacei[t, r] = -(v.emissint[t, r] / v.emissint[t - 1, r] - 1.) * 100.
I see in the FUND model the scenconverter.jl script isn’t actually included, and rather it reads in the parameters directly from a data file, so I just wanted to double check whether the parameters read into the model from the csv data files are calculated using the above definition or another?
For context, I am asking this question because I’m trying to read in a different CO2 emissions vector, and want to make sure that
acei are consistent with this exogenous vector.
