An investigatory report by Greenpeace led to allegations that South Korean machinery manufacturer HD Hyundai Construction Equipment (HD HCE) contributed to deforestation in the Amazon by providing excavators to illegal gold miners operating within Indigenous territories, in areas of Brazil which were degraded 202% more between 2019 and 2021 compared to the preceding decade._ In the Indigenous lands of Yanomami, Munduruku, and Kayapó, 75 Hyundai excavators were identified during aerial surveys conducted between 2021 and 2023. Illicit mining activities have led to a humanitarian crisis in these areas; for example, contaminated rivers have posed health risks to Yanomami adults and children.
