Alennium, CBA’s new
sustainable aluminum label.

CBA is committed to supplying low-carbon aluminum for a better world. And our Alennium mark is here to reinforce this commitment—a new label identifying articles made with our low-carbon aluminum.

You can now quickly identify products that are helping to build a more sustainable world for everyone in the next millennium.

Alennium connects our efforts to those of our partners who understand the role and responsibility we have to society. After all, sustainability is a key part of our mission and the future we’re building together.

What products are eligible to display the Alennium mark?

The new mark can be displayed on products made with our low-carbon aluminum—emitting less than 4 tons of CO2 per ton of smelted aluminum.

Why are Alennium-labeled products low-carbon?

CBA produces primary aluminum with 100% renewable electricity.

Our smelter emissions were just 2.56 tons of CO2 equivalent per ton of aluminum in 2021, and we are currently upgrading our technology to further cut emissions.

Our refinery produces aluminum oxide with one of the lowest emissions levels in the world, using steam produced from reforested wood biomass.

And despite our industry-leading performance, we are working toward a target to further reduce our carbon emissions by 40%—from mine to casthouse.

We were the first primary aluminum manufacturer to set emissions reduction targets approved by the Science Based Targets initiative (SBTi). This means that our targets are aligned with the Paris Agreement and are effectively helping to mitigate climate change.

Our new Alennium label expresses who we are and is integral to our environmental, social and governance (ESG) initiatives.


We have chosen to take on a leading role in building a better society. We know that our actions can have a major positive impact. That is why we are seeking to bring about change by fostering a more collaborative world.
