Calculate Embedded Emissions for Unwrought Aluminium (HS7601)

Enter your input

Payable emissions (tCO₂e/t)

Total CBAM Cost (€)

Notes:
There may be a difference when calculating the price with respect to import volume, carbon price, and benchmark emissions, as the embedded formula may result in minor variations due to decimal rounding. Therefore, the actual value may vary.

CBAM is applicable to trade volumes starting from 50 metric tonnes. For trade volumes below 50 metric tonnes, CBAM does not apply.

Usage Procedure – How to use the CBAM Calculator Sheet

Enter or update values only in the INPUT
PARAMETERS section (Highlighted in blue) , including
the carbon price, benchmark emissions, CBAM
chargeable percentage (as per the phase-in year),
and imported quantity.

The system will automatically calculate the payable
emissions and the total CBAM cost (€) based on the
inputs provided.

Notes:
• Change any input value to automatically update CBAM cost.
• Formula used: Carbon price × payable emissions × quantity.
• Model aligned with CBAM supplier-side illustrative methodology.

South32 pulls the plug on Mozal aluminium smelter operations after power deal impasse

EDITED BY : NILANJANA BANERJEE 1MINS READ

Mozal Smelter Shutdown

Unable to secure a long-term, affordable electricity supply, South32 has placed the Mozal Aluminium Smelter near Maputo, Mozambique, on care and maintenance, effective March 15, 2026. The move effectively brings 25 years of primary aluminium production at the site to a conclusion.

The step has been taken despite six years of negotiations with the Government of Mozambique, Eskom and other stakeholders regarding future power arrangements for the aluminium smelter beyond March 2026.

While the facility remains idle, South32 expects to incur one-off costs of estimated USD 60 million, as well as current annual care and maintenance expenses worth approximately USD 5 million.

From the shutdown onwards, the alumina received by the Mozal smelter will be redirected from Worsley Alumina Refinery to third-party customers, with sales based on index-linked pricing. This shift will alter the company’s sales mix and reduce the smelter’s contribution to Mozambique’s industrial economy.
