The value of Aluminium

At CBA we believe our business is more than just about aluminium—it’s about the way that, through aluminium, we can create and share value with the world in an ethical and healthy manner. Ours is a time of profound change, marked by social and environmental challenges that are requiring companies, their stakeholders, governments, the third sector and broader society to work together in taking care of people and our planet.

Recognizing this responsibility, we have long chosen the path of sustainability, and in the course of our journey we have come to understand that sustainability needs to be embedded in each of our decisions. We have also learned that sustainability requires an essentially collaborative mindset. This is why we have decided to not only transform our own business, but to take a leading role more broadly in building a better society. We want to help point the way and engage our stakeholders and the wider market in this journey.

To achieve this ambition, as expressed in our Manifesto, we have put sustainability at the very heart of our strategy. In addition to adopting and supporting the ten principles of the UN’s 2030 Agenda and the Global Compact—the world’s largest corporate sustainability initiative around human rights, labor, environment and anti-corruption—we have strengthened our ESG culture by committing to a set of environmental, social and governance goals to be achieved by 2030.

Our mission

As part of our efforts to drive efficiencies and investments in innovation, we will continue to develop increasingly low-carbon aluminum products and sustainable solutions to the world’s challenges. Another core part of our proposition is helping to develop the regions where we operate and positively influencing the end-to-end aluminum value chain.

A more collaborative world.

That’s what sustainability means to CBA.


Our Manifesto

We make the change

Since our beginnings, we have been genuinely committed to making a positive impact on society and on the environment. But we know that when it comes to sustainability there is no finish line.

We transform things

As leaders, we recognize our responsibility to the market and to society. We know that our actions can have a major positive impact. When we raise the bar, we start a chain reaction that drives transformations beyond our industry. That is why our purpose goes beyond our company walls. It’s not just about transforming our own way of doing business. We want to increase awareness more broadly.

We evolved together

We want to inspire and engage our industry toward becoming more sustainable. Because to us it only makes sense if we do it together. Together with our employees, customers, suppliers, partners, communities and investors. A sustainable world is a more collaborative world. We know that a better future can only exist if we all work together to make our world better and more sustainable today.

Our Strategy

CBA’s ESG Strategy 2030 translates our decision to embed environmental, social and governance factors in our core business into actions that are aligned with global trends in business sustainability.

Our 2030 goals will be achieved through a set of initiatives across 15 programs, grouped into 10 levers—4 in the environmental pillar, 2 in the social pillar, 3 in the governance pillar, and 1 cross-cutting lever spanning all business areas.


Our Mandato

By 2030, deliver an offering of low-carbon aluminum products and sustainable solutions to the world’s problems, while developing the regions where we operate and positively influencing the end-to-end aluminum value chain.

ESG Strategy

Certifications and Commitments

Our certifications to the highest global standards, and our collaborations with prestigious organizations specializing in sustainability, inspire us to achieve further progress on our ESG strategy.


Global Compact

We support the 2030 Agenda, the 17 Sustainable Development Goals (SDGs) and the UN Global Compact’s ten principles on human rights, labor, environment and anti-corruption. We also actively participate in the Thematic Groups on Energy & Climate, Anti-corruption, Human Rights & Labor, and Action for the SDGs. And we are one of the 15 companies selected to participate in the Young SDG Innovators Program, launched in 2021.



CBA was the first aluminum company in the Americas to receive combined certification against the ASI Performance and Chain of Custody Standards. The certification process covered three mine operations, two plants and our offices in São Paulo (SP), with our Metalex operation due to be certified in 2021. ASI certification attests that we adhere to internationally recognized ESG standards in the production of aluminum, across each stage of the value chain.
