The '12/44' confused me here. It is probably right, but maybe transform vm_peatland_emis into correct units before entering this equation. No other equation needs unit transformation in this module.

The unit of vm_peatland_emis is t CO2eq per year. Since im_pollutant_prices is in USD/tC, I have to convert the C price into CO2 price.
If I do the conversion in the peatland module, vm_peatland_emis would have the unit t Ceq per year. This unit seems strange to me. At least I have never seen it anywhere before.

maybe for clarity more meaningful names for the 'Helper for peatland initialization'?

Weight for intermediate calculation in peatland initialization (1)
Better?

I guess I finally understand the role of unused and I think after the adding of the missing constrains in the presolve (which you already did), you have a go from my side.
The understanding of the module (specifically the management set) is a bit complicated, but the explanation in the peatland paper works good. if it is published you will (and should) probably add the reference in the module file.
