Fri Nov 14 11:40:23 UTC 2025: Summary:
A London judge has ruled that BHP Group, a global mining giant, is liable for the 2015 dam collapse in Mariana, Brazil, which is considered Brazil’s worst environmental disaster. The dam, owned by Samarco (jointly owned by BHP and Vale), released toxic waste into the Doce River, killing 19 people, devastating villages, and causing widespread environmental damage. Around 600,000 Brazilians are seeking significant compensation. The ruling establishes liability, with a second trial phase to determine the amount of damages. The case was filed in the UK due to BHP’s legal entity’s location in London at the time of the disaster. This comes shortly after a multibillion-dollar settlement between the Brazilian government and the mining companies involved.

BHP Found Liable in Landmark Ruling Over 2015 Brazilian Dam Disaster
London – November 14, 2025 – A London High Court judge has ruled that global mining giant BHP Group is liable for the devastating 2015 dam collapse in Mariana, Brazil, which resulted in 19 deaths and widespread environmental destruction. The ruling marks a significant victory for the hundreds of thousands of Brazilians seeking compensation for the disaster.
Justice Finola O’Farrell stated that BHP, a 50% owner of Samarco, the Brazilian company operating the iron ore mine where the dam failed, was responsible despite not directly owning the dam. The collapse unleashed a torrent of toxic mining waste into the Doce River, devastating the village of Bento Rodrigues and causing extensive damage to the surrounding ecosystem, including killing an estimated 14 tons of freshwater fish and polluting over 600 kilometers of the river.
“This ruling is a crucial step towards justice for the victims of this horrific environmental catastrophe,” stated a spokesperson for the plaintiffs. “It acknowledges BHP’s responsibility in this disaster and paves the way for them to be held accountable for the immense damage caused.”
The lawsuit was filed in the UK due to BHP’s legal presence in London at the time of the collapse. While a settlement was recently reached between the Brazilian government and Samarco’s parent companies (BHP and Vale), the London trial proceeded to determine liability. A second phase of the trial will now determine the amount of damages to be awarded to the approximately 600,000 Brazilians seeking 36 billion pounds (US$47 billion) in compensation.
The ruling has been met with strong reactions, with environmental groups hailing it as a victory for corporate accountability in the face of environmental disasters. BHP has maintained that the UK legal action was unnecessary, claiming it duplicated proceedings in Brazil. The ruling, however, underscores the potential for companies to be held accountable in international courts for their actions abroad. The Doce River, a deity to the Krenak Indigenous people, remains significantly damaged a decade after the disaster, highlighting the long-term impact of the environmental tragedy.
