Sigma Lithium Demonstrates Excellence in Environmental Performance Filing Data Collected by External Experts Measuring Low Noise, Low Dust, Low Vibrations
·
Executive Summary
Sigma Lithium Corporation has released comprehensive environmental performance data spanning twelve months through May 2026, demonstrating exceptional environmental stewardship across its Brazilian lithium operations. The company filed independently collected data from third-party experts measuring dust, noise, and vibration levels across four neighboring communities, with results significantly exceeding regulatory requirements.
The environmental monitoring results show Sigma Lithium operating 560% better than recommended standards for total suspended particles and 350% better for particles below 2.5 micrometers. Noise monitoring across 95 measurement campaigns during both day and night periods demonstrated full compliance with Brazilian Technical Standards Association (ABNT) requirements. Vibration measurements showed extremely low levels that barely registered on seismograph scales when compared to ABNT limits.
This data release serves a strategic purpose beyond demonstrating environmental excellence, as it directly addresses legal challenges the company faces in local Brazilian courts. The objective, third-party collected evidence refutes what the company characterizes as 'baseless and unproven claims' currently under appeal in Minas Gerais state courts. The comprehensive nature of the data collection and the significant margins by which standards are exceeded provide strong defensive positioning for ongoing legal proceedings.
As the largest lithium oxide concentrate producer in the Americas, Sigma Lithium's environmental performance data reinforces its positioning in the critical minerals supply chain while addressing increasing scrutiny of mining operations' environmental impact. The company emphasizes that its operations support approximately 19,000 livelihoods and benefit an estimated 80,000 people in one of Brazil's most economically challenged regions, highlighting the social dimension of its sustainability commitments.
