This week, Brazil’s three biggest retailers announced that they will not purchase beef from blacklisted ranchers in the Amazon. According to a recently released report from Greenpeace, certain ranchers in the state of Pará are responsible for deforesting the Amazon and are causing destruction at a rapid rate. In fact, the report shows that ranching is the number one cause of Amazon deforestation.

In turn, CBD (the Pão de Açucar chain), Carrefour, and Walmart, along with 72 other retailers will stop buying meat from the offending ranchers. Also, the big three companies have decided to monitor their beef shipments closely and to conduct an assessment to make sure no meat comes from the deforesting ranchers. CBD reported a total of 11 banned companies.

The Greenpeace faults the Brazilian government for failing to live up to its commitment to reducing Amazon deforestion.
