Responding to a recent New York Times piece linking the horrific warfare in the Congo with the minerals used in our gadgets, Steve Jobs wrote a new iPhone 4 customer explaining Apple’s policy in dealing with mineral purchases:
We require all of our suppliers to certify in writing that they use conflict few materials. But honestly there is no way for them to be sure. Until someone invents a way to chemically trace minerals from the source mine, it’s a very difficult problem.
That’s a refreshingly blunt admission of relative impotence: Apple’s doing what it can, but ultimately, their suppliers are in turn supplied by people who could well be lying about their source. Short of a way to independently verify where minerals are coming from, Apple’s got to take people at their words.
