Several major shoe brands have demanded a moratorium on the destruction of the Amazon rainforest. Clark, Adidas, Nike and Timberland are among the brands that are putting pressure on suppliers to make changes. According to this article around 65 to 75% of deforestation is linked to the growth of ranching. As well as the moratorium on leather from newly deforested areas the footwear makers want suppliers to bring in a traceability system which will guarantee the source of all leather. Currently some Brazilian companies linked to rainforest destruction export products to blue chip companies across the world. The three major processors Bertin, JBS and Marfrig have now agreed to reject cattle from illegally deforested land. The footwear companies will also refuse to buy leather which is sourced from farms on both legally and illegally deforested land.
