Its suppliers generate about 200 million tonnes per year, said Jim Stanway, Wal-Mart's director of project development, at a conference on carbon strategy.
"Those are much bigger funds to go fishing in," said Stanway. "That's where our strategy moved to," he said, adding that it is also cutting its direct emissions.
When Wal-Mart first sent engineers into supply-chain factories, "what we found absolutely staggered us," said Stanway. He said they helped cut electricity bills by 60 percent at the first factory they audited by installing readily available low emissions lighting and technologies.
