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.

Aluminium price declines on increased output in China and weaker demand in Japan

EDITED BY : TRISHA HAZRA 2MINS READ

Aluminium prices dipped by 0.79 per cent, settling at USD 257.2, as the market continued to grapple with volatility stemming from inconsistent supply and demand. In August 2025, China's domestic aluminium production saw a year-on-year increase of 1.22 per cent and a month-on-month rise of 0.33 per cent.

China’s rising aluminium production in August fails to halt price decline

On the trade side, imports showed a robust growth, climbing 12.9 per cent year-on-year in August to reach 320,000 tonnes. Cumulatively, imports for the first eight months of 2025 hit 2.65 million tonnes, reflecting a 2.7 per cent increase compared to the same timeframe last year.

Amid the rising output, there have been evidences for regional demand drops, such as in Japan, where aluminium stocks increased by 6.3 per cent M-o-M in August, resulting in lower offerings of shipment premiums between USD 98 and USD 103 per tonne.

On the other hand, LME aluminium inventories took a significant hit, dropping nearly 100,000 tonnes in the first part of September, leaving stocks at 375,000 tonnes and showing just how tight availability is becoming. According to WBMS, the global aluminium market faced a deficit of 119,900 tonnes in July, pushing the total shortfall for January to July 2025 to 985,300 tonnes.

In August, China saw a 4 per cent year-on-year increase in its output of 10 nonferrous metals, which include copper, aluminium, lead, zinc and nickel, totalling 6.62 million tonnes. Over the first eight months of 2025, the overall production hit 52.05 million tonnes, reflecting a 5.4 per cent rise compared to the previous year, including tin, antimony, mercury, magnesium and titanium.

Overall, the increase in production amid sluggish demand led to aluminium price fall. A slowdown in manufacturing activity in China and the US, combined with a rise in domestic supply, put pressure on prices. By August, the average price had decreased to RMB 2,121 (USD 299.03) per tonne, a figure that still supports profitable production, particularly in areas that enjoy low-cost energy.

In the meantime, aluminium producers in the southwestern part of Yunnan province have been keeping their output strong, due to plentiful hydropower resources available in the area.
