Apple is planning to do a pollution audit of one of its parts suppliers, a Chinese environmental group tells the Wall Street Journal. A vice director for the Institute of Public and Environmental Affairs, Wang Ding, elaborates that the supplier makes printed circuit boards, but Wang is refusing to name the company. She does say that the IPE will be participating in the audit, and have help from professional auditors. The group is hoping to audit other Apple suppliers as well, but Wang adds that this is dependent "on Apple's and its suppliers' actions."
