Hi Andreas,
unfortunately there is no front end function for that yet, but you can calculate it in the following way:
Multiply electricity generation with specific emissions, divide by efficiency.
Assuming you have constant efficiencies:
(n.snapshot_weightings.generators @ n.generators_t.p) / n.generators.efficiency * n.generators.carrier.map(n.carrier.co2_emissions)
If other components than generators associated with carriers with nonzero specific emissions, you need to repeat. For stores take the difference between initial and final state of charge.
Best wishes,
Fabian N
One small addition: As the CO2 prices have influence on the dispathcing/extension of generators, there has to be some kind of calculation in the background, I assume. Maybe results are stored somewhere as well (hopefully :) )
