According to a EurActiv.com news article, entitled EU Drafts Conflict Minerals Law, With Opt-In Clause, when the proposed rule is released tomorrow, March 5th, it will be limited to the same minerals identified by the U.S. conflict minerals rule (tin, tantalum, tungsten and gold) and the rule will not contain any compulsory measures, but will instead incentivize companies to conduct due diligence on their supply chains.

When asked to comment on the draft of the EU rule, a spokeswoman for the Global Witness campaign stated, “This weak proposal risks undermining states’ duty to protect human rights and could even be redundant. An opt-in scheme would be tantamount to the EU saying that it’s ok for companies to choose not to source responsibly.”

If released tomorrow as anticipated, the rule will likely be voted on in September 2014 and if approved become effective at the beginning of 2015.
