An investigation by Mighty Earth revealed that 27 JBS meatpacking plants—supplying major retailers such as Carrefour, Casino, Grupo Mateus, and Sendas/Assaí supermarkets in Brazil—were linked to nearly 470,000 hectares of deforestation in the Amazon and Cerrado biomes between 2009 and 2023. This deforested area is equivalent to seven times the size of London.
