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.

Alcoa Corporation expects alumina shipments from its Pinjarra refinery in Australia to decline by about 120,000 tonnes in the second quarter compared with the first quarter, following disruptions caused by Cyclone Narelle.

Speaking at the Wells Fargo Industrials & Materials Conference in Chicago, Alcoa Chief Financial Officer Molly Beerman said the cyclone, which struck Australia in March, disrupted liquefied natural gas supplies to the company's Pinjarra alumina refinery.

The Pinjarra facility has an annual alumina production capacity of 4.7 million tonnes.

According to Beerman, the disruption is expected to increase second-quarter production costs at the refinery by about USD 30 million.

Alcoa is also facing higher costs at its Sao Luis alumina refinery in Brazil. Beerman said the company expects an additional USD 15 million in fuel costs during the second quarter due to the ongoing conflict in the Middle East.

While the Sao Luis refinery remains profitable, Beerman said Alcoa's alumina business is currently under significant pressure.

She noted that the company's Western Australian refineries are facing challenges due to low alumina prices and lower-quality bauxite supplies.

"As a whole, the segment will be underwater," Beerman said.

The company is also assisting aluminium smelter customers in the Middle East by redirecting some contracted alumina shipments to alternative destinations, mainly China, because of production constraints linked to the regional conflict.

Following the comments, Alcoa's shares fell 9.5 per cent on Wednesday to USD 65.55.
