Does hydro power lower the CBAM figure for aluminium from Puerto Madryn?
Not the charge. For aluminium only direct emissions count toward CBAM: anode CO2, perfluorocarbons and cast house fuel. Hydro and wind power lower the reported indirect emissions and the Scope 3 footprint buyers see, which matters for low carbon contracts.
What the charge covers
- Anode carbon in the pots.
- CF4 and C2F6 from anode effects.
- Casting furnace fuel.
Where power helps
Buyers comparing footprints count power. A smelter on hydro and wind can show a much lower cradle to gate figure than one on coal.
Mixed supply
If part of the power comes from gas, ask for the share by year so the claim matches the supply.
What Senseible does here
Senseible keeps each site's fuel, power and production records together, so the embedded emissions you send an EU importer trace back to dated documents.
