Vale reports meaningful absolute emissions reductions and 84% renewable electricity globally, but operates at a scale (466 MtCO₂e total) that dwarfs these gains. Two catastrophic dam collapses—Mariana (2015) and Brumadinho (2019)—killed 289 people and devastated major river systems. An SEC fraud settlement and Brazilian fines for withholding dam safety information reveal systemic transparency failures. Nature impact claims are contradicted by documented environmental devastation.
