… subsector and SE carrier, for chemical feedstocks which are not available for carbon capture

pm_IndstCO2Captured is essentially Emissions × Capture Share

  • Emissions is (FE - NE) × factor
  • Capture Share is ∑ CCS / ∑ Emissions, so ∑ CCS / ∑ (FE - NE) × factor
    so pm_IndstCO2Captured = (FE - NE) × factor × ∑ CCS / ∑ (FE - NE) × factor
    but NE happens to be just an exogenous share of FE so actually
    pm_IndstCO2Captured = FE × λ × factor × ∑ CCS / ∑ FE × λ × factor ⇔ FE × λ × factor × ∑ CCS / λ × ∑ FE × factor ⇔ FE × factor × ∑ CCS /∑ FE × factor
    So here and now, non-energy demand actually does not matter. Should still be fixed though, but mainly on the REMIND side, since this is just a quick fix for a REMIND bug that we cannot remove anymore, backwards compatibility be praised.

Ok, then let's add non-energy to the pm_IndstCO2Captured calculation in REMIND. Moreover, I would say the temporary pm_IndstCO2Captured calculation in reportEmi can be removed as your fix of the capture share is from August 2023. We do not need backwards compatibility here anymore.
