Sigma Lithium Continues to Lead the Charge for Sustainable Supply Chains at COP28

The pioneering practices of Sigma Lithium in clean technology and environmental sustainability have solidified its position as a global leader in decarbonized supply chains for electric vehicles.

Sigma Lithium Corporation has once again made a significant impact at the Conference of Parties (COP), showcasing its commitment to clean technology and sustainable supply chains. As a leading global lithium producer, Sigma Lithium is dedicated to powering the next generation of electric vehicles with carbon-neutral, responsibly sourced lithium concentrate. With its participation in COP28 in Dubai, the company aims to contribute to the global dialogue on environmental and social sustainability in industrial and mineral supply chains.

Shaping the Global Dialogue on Sustainability

Sigma Lithium has been actively participating in COP since 2019, using its platform to advocate for decarbonization, ecosystem preservation, and social justice. The company has been at the forefront of thought leadership, engaging directly with world leaders and participating in bilateral meetings to discuss the development of sustainable supply chains. By embodying the principles of decarbonization, Sigma Lithium aims to promote a just energy transition and limit global warming to 1.5 degrees Celsius above pre-industrial levels.

Key Topics at COP28

At COP28, key topics of discussion include supply chain decarbonization, Brazil’s initiatives in leveraging its natural resources for industrial decarbonization, the role of the mining industry in enabling the energy transition, and women’s economic and political empowerment. Sigma Lithium’s CEO, Ana Cabral, will deliver a keynote presentation on “Decarbonizing Supply Chains and Accelerating Industrial Transition” at the Investment Track of COP28. The company is actively engaged in critical dialogues on the decarbonization of global industrial and mineral supply chains.

Pioneering Sustainable Practices

Sigma Lithium’s commitment to sustainability is evident in its innovative practices. The company produces Triple Zero Green Lithium, a battery-grade, carbon-neutral, and zero hazardous chemicals concentrate. Its state-of-the-art Greentech lithium plant in Brazil uses 100% renewable energy and recycled water, contributing to a cleaner production process. Sigma Lithium also focuses on water preservation, utilizing 100% sewage water for its plant and preserving the Piaui Creek as a source of drinking water for surrounding communities.

Building a Sustainable Lithium Supply Chain

Sigma Lithium’s efforts extend beyond its own operations. The company has announced a deal to achieve “Zero Tailings” by selling the high-purity, zero hazardous chemicals tailings generated by its Greentech Plant. These tailings will be upcycled into battery-grade lithium concentrate for use in electric vehicle battery production. By partnering with Glencore, Sigma Lithium aims to build a low-carbon, environmentally and socially sustainable global lithium supply chain.

Offset Carbon Footprint

Sigma Lithium is committed to offsetting its carbon footprint. By purchasing carbon credits from Carbonext, the company ensures that its carbon emissions are neutralized. This commitment to carbon neutrality is reflected in its recent shipment of Triple Zero Green Lithium concentrate to Glencore, which was made carbon neutral through the use of carbon credits.


Sigma Lithium’s participation at COP28 highlights its leadership in delivering sustainable supply chains for electric vehicles. Through its pioneering practices and commitment to environmental and social sustainability, the company is setting a new standard in the battery materials industry. By promoting decarbonization, ecosystem preservation, and social justice, Sigma Lithium is driving the transition to a cleaner and more sustainable future.
