I explore a clean lighting scenario where I replace kerosene with clean lighting . The results on climate warming show black carbon aerosol having a cooling effect.

Not sure why this is happening. I just edited penetration rates in the clean lighting scenario.

Any help is appreciated

The Environmental Effects are related to specific environmental loading. When energy type changes, the corresponding Multiple effects should also be changed. If the you are sure that clean lighting has no emissions, the Mutiple effects should not be added. Hope this helps.
