Mining projects around the world often promise development and economic growth, yet their legacies reveal a far more complicated story. Sites like Cerrejón in Colombia, Córrego do Feijão and Samarco in Brazil show how environmental, social, and human rights risks can ripple through communities for decades. Rivers are poisoned, soils contaminated, and ecosystems devastated, while thousands of residents face health crises, displacement, and loss of livelihoods. Legal actions, class lawsuits, and ongoing remediation efforts illustrate that the consequences of these operations do not end when production stops. Communities continue to grapple with the aftermath, from toxic waste and tailings spills to the psychological scars of displacement and conflict.
What are the most pressing ESG challenges currently facing the mining sector? Read on to find out.
The Córrego do Feijão Mine is facing serious ESG controversies following a dam collapse that resulted in 270 fatalities and contamination of the Paraopeba River. Indigenous villagers still lack safe land and access to clean water and food. The operating company, Vale, is dealing with ongoing legal challenges, including fines and criminal charges for negligence and bribery. Environmental and social impacts persist, with continued monitoring of water quality and safety risks from existing dams. Governance issues remain significant, highlighted by employee arrests and scrutiny over manipulated audits, prompting calls from local and international NGOs for improved remediation efforts and oversight of the mine’s operations.
Cerrejón Mine faces significant ESG issues, particularly in environmental and social areas. Its expansion has displaced over 20,000 indigenous people, especially from the Wayúu community, leading to severe health problems and the deaths of 5,000 children. Environmental concerns include the diversion of the Bruno Stream, excessive water use during droughts, and significant air and water pollution. Labor unrest persists, with over 4,600 unionized workers striking over job cuts and unsafe conditions. The mine continues to face international criticism for violating local community rights and harming regional ecosystems.
Samarco Mine faces intense ESG scrutiny nearly a decade after the 2015 Fundão dam collapse, with over 700,000 claimants in a $44 billion lawsuit for contaminated water and pollution. The operator risks bankruptcy due to environmental liabilities and failed debt restructuring, exacerbating financial instability. Ongoing issues include heavy metal contamination in wildlife and dust pollution exceeding health standards, prompting NGOs to demand the operator's removal from the UN Global Compact. Governance concerns have risen with employee arrests linked to safety protocol violations and falsified audits, raising questions about corporate accountability.
