Fashion chain H&M says it won't buy leather from Brazil until it's sure cattle production isn't fueling forest fires in the Amazon.

H&M joins VF Corporation, owner of Timberland, Vans, North Face and other brands, in halting leather purchases from Brazil until suppliers show their wares are not connected to widespread deforestation.

More than 77,000 fires have erupted in the Amazon this year. More than 80% of deforestation in Brazil in recent decades has been linked to pasture expansion.

Swedish fashion retailer H&M says it will stop purchasing leather from Brazil to distance itself from the cattle farming and pasture-clearing that is believed to be fueling the fires burning the Amazon rainforest.

"Due to the severe fires in the Brazilian part of the Amazon rainforest, and the connections to cattle production, we have decided to place a temporary ban on leather from Brazil," the company said in a statement to CBS MoneyWatch.

The world's second-largest clothing retailer reiterated that the ban is temporary, and will remain in effect until "there are credible assurance systems in place to verify that the leather does not contribute to environmental harm in the Amazon."
