Issue running a Monte Carlo simulation on premise-modified databases (scenario LCA mode) #1628

  • Yes, I have updated AB and still experience this issue

What happened?

Hello,

I am encountering an issue when I perform Monte Carlo simulations in the scenario LCA mode (using an SDF file for the REMIND-SSP2-PkBudg1150 scenarios for the years 2025 to 2060). I know the issue is not my SDF file, since it works properly for deterministic LCIA.

When I run the Monte Carlo simulation in Scenario LCA mode, the resulting mean for all years is centered around the value I would obtain under a standard LCA (therefore ignoring premise-induced modifications).

For example for GWP-1000 impacts (RECIPE 2016 H)
I should obtain a mean centered around 50 kgCO2-eq/kWh in 2050 (from my deterministic Scenario Mode calculation).
I rather obtain a mean centered around 114 kgCO2-eq/kWh (result I obtain in Standard LCA mode as well)

I have tried rebuilding my calculation setup/restarting AB. My LCIs are built using databases generated from the ScenarioLink plug in.

Thank you in advance for your help and for this great software!
