Sustainability is the foundation of our business.

We understand our short and long-term impacts on people and the planet, and we act to prevent and reduce them throughout our value chain. We work together with our communities on their sustainable development.

In our mining operations, we reuse 95% of the water in the ore processing circuit and continue to explore opportunities to further reduce our footprint on the environment.

We create opportunities in the clean energy industry that will benefit people around the world. Our vanadium redox flow batteries (VRFBs) are an innovative solution to store renewable energy for a low-carbon future.

Our vanadium products are used in responsible processes such as providing fuel efficiency in the aerospace industry and reducing the environmental impact along the steel production chain.

We are proud of our accomplishments made since we began operations and look forward to continually improving as we grow and develop responsible products and solutions that meet the needs of tomorrow.

Climate change: risks and opportunities

Largo is well-positioned to minimize transition risks and is already taking advantage of opportunities.


Located in Northeast Brazil, Largo’s Maracás Menchen Mine could be exposed to acute and chronic physical risks related to rainstorms and increased temperatures during its operational mine life of 20 years. Reduced production capacity is the main potential financial impact and the Company is actively mitigating risks related to changes in rain precipitation and volume.


Vanadium presents opportunities to reduce GHG emissions and minimize climate change through its use as an alloying element in greener steel applications as well as integrating renewable energy through its use in long duration energy storage via vanadium-based batteries. Largo’s clean energy business focusses on the sale of vanadium-based battery components to renewable energy storage customers. The long-duration energy storage market is growing, with expected maturity around 2030-2035. Vanadium batteries offer unique advantages due to a variety of innovations that enable an efficient, safe solution that is fully recyclable at the end of their expected 25-year-plus lifespan, meeting increasingly stringent regulatory requirements.

Our main physical risk is from weather events and changes in precipitation patterns—which could cause future droughts, for example—in the region of our mine. We already practice good water stewardship—our operations reuse over 90% of the water used in processing.

Disclosure and transparency

Vanadium presents opportunities to reduce GHG emissions and minimize climate change. VRFBs can be an essential component in renewable, clean power systems. Our batteries are expected to have a long lifespan and meet the increasingly stringent regulatory requirements for the repurposing or remanufacturing of battery chemistry and components. These safe and durable batteries will serve the fast growing market for renewable long duration energy storage.
