## Technical Overview & Governing Rules
Primary aluminum smelting via the Hall-Héroult process consumes an average of 14.5 to 15.5 MWh of electricity per tonne of aluminum. Because of this high electricity intensity, Scope 2 indirect emissions vary drastically depending on the exporter country electricity grid carbon intensity.

## Frequently Asked Questions & Edge Cases
### Q: Why are Scope 2 emissions so significant for aluminum under CBAM?
**A:** Primary smelting requires ~14.5 MWh/t of electricity, making grid carbon intensity the dominant emission driver.
