ESG Strategy


Engaging around environmental, social and governance issues has always been as important to us at the quality of our aluminum. That is why we are continuously evolving to be ever more sustainable—for the benefit of people, the planet, and ourselves.

In 2018 we implemented a strategy on sustainability, setting targets through 2030. In 2020, this strategy matured and evolved into an ESG (Environmental, Social and Governance) model.

Doing our part in building a better future is not enough. We want to lead and point the way to inspire our employees, partners, customers and suppliers.

Sustainability is among the core pillars of our business. Learn more here.


Mandate: 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.

CDP In our first-time disclosures to the Climate Disclosure Project (CDP), we received a leadership-level score of A-, the highest possible rating for organizations making non-public disclosures. The CDP is recognized globally as the gold standard for environmental reporting. Awarded by the CDP: A not-for-profit charity that runs the global disclosure system for investors, companies, cities, states and regions to manage their environmental impacts—one of the most widely recognized by investors globally.


Global Compact We are committed to the Global Compact’s ten principles on human rights, labor, the environment and anti-corruption. We are members of the Thematic Groups on Energy & Climate, Anti-corruption, Human Rights & Labor, and Action for the Sustainable Development Goals (SDGs).
São Paulo Environmental Agreement We have subscribed to this agreement and participated in meetings of the Environmental Chamber for Climate Change.
CBA CBA has committed to the Science Based Targets initiative to set and meet science-based targets for limiting global temperature rise.
Young SDG Innovators Program We were among the 15 companies selected to participate in this initiative.
CEBDS We are a member of the Brazilian Business Council for Sustainable Development (CEBDS)
TCFD (Task Force on Climate-Related Financial Disclosures) CBA has partnered with the Task Force on Climate-Related Financial Disclosures (TCFD), a task force that brings together companies from around the world to develop a common standard for assessing, measuring and disclosing financial risks related to climate 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. There’s always more to be done. And we are determined do it.


And we do

We think differently each day to create new solutions to today’s problems. 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 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.


When it comes to sustainability, we walk the talk.

In 2020, we entered into the first green brazilian Export Credit Notes to finance sustainable projects and promote exports. In 2021, we went further and issued our first green debentures, which aims to improve the environmental performance of our production structure. Overall, CBA has already raised R$ 730 million in green financing, amongst three different transactions. In the same year, we secured a revolving credit facility of USD 100 million, which, aligned with the Companies’ ESG goals, we commit to an annual reduction in greenhouse gas emissions by 2025.

Green Loans


Green loans are bank loans in which the proceeds are used toward sustainable projects, often requiring borrowers to report on social and environmental Key Performance Indicators (KPIs). They are part of a global trend in the financial services industry, which is increasingly using ESG criteria in evaluating loans and investments.


Independent consultants assessed CBA’s project portfolio and whether the loans would qualify as green finance


CBA undertook a commitment to invest in these projects and to monitor and report performance indicators, such as reductions of direct GHG emissions, waste volumes, raw materials and water withdrawals.


CBA raised approximately R$ 500 million in two green loans issues, in February and August 2020. The loans have average maturities of seven years and four years, respectively.

Use of the funds

The proceeds from the loans are being used to fund pollution reduction (climate change mitigation and waste management) and water stewardship projects.
