Apple and Google praised for taking action on conflict minerals

Advocacy group Enough put out a list of the tech and jewelry companies doing the most and least around use of conflict minerals – things like gold, tin, tungsten, and tantalum that are mined in violence-torn parts of the Congo.

Tech giants Apple, Google, Microsoft and HP were at the top of the group's list, with retailers like Costco, Sears, Nieman-Marcus and Walmart at the bottom.

Methodology: The highest possible score is 120 points, but extra credit is possible. Companies are scored based on their commitment to a conflict-free mineral sourcing policy, outside audits, their support for communities in the Congo, and advocacy; Data: The Enough Project; Chart: Chris Canipe / Axios
