How does a ferroalloy plant count the emissions of manganese ore from Chiatura?

If you do not run the mine, the ore is Scope 3 purchased goods: mining diesel, electricity for washing and concentrating, and freight to your plant. If your group runs the mine, those emissions are your own Scope 1 and 2. Ore is not a CBAM precursor for ferro-manganese.

What the mine adds

Control decides scope

Emissions follow control under the GHG Protocol. Same group and operated by you: Scope 1 and 2. Bought ore: Scope 3, category 1.

For CBAM

CBAM counts the smelter's direct emissions and listed precursors. Manganese ore is not listed, so it stays out of the CBAM figure.

What Senseible does here

Senseible turns supplier invoices into a Scope 3 record with the supplier, quantity and factor behind every figure, so you can see which supplier data is still missing.
