A study names firms that buy products from areas with deforestation

ONE OF THE factors slowing progress against climate change is a lack of corporate accountability. In the Amazon rainforest, which absorbs 3% of global carbon emissions, a France-size swathe of foliage has vanished since 1970. Nearly all deforestation in Brazil today is illegal. But we do not know which firms use suppliers that operate on illegally cleared land (see article). Even beef exporters are in the dark: they mostly record where their cattle were fattened, not where they were reared.
