On 3 and 4 May 2012, IPFM is presenting a preliminary set of proposals on "Increasing Transparency of Nuclear-warhead and Fissile-material Stocks as a Step Toward Disarmament" at the First Preparatory Committee for the 2015 Nuclear Non-Proliferation Treaty Review Conference, being held in Vienna.

The "Action Plan on Nuclear Disarmament" agreed at the 2010 nuclear Non-Proliferation Treaty (NPT) Review Conference affirmed that "nuclear disarmament and achieving the peace and security of a world without nuclear weapons will require openness and cooperation, and ... enhanced confidence through increased transparency and effective verification."

To help inform this process, IPFM will offer a path for how NPT nuclear weapons states could fulfill their transparency commitments through a series of successively more detailed declarations of the numbers, status and histories of their nuclear warhead and fissile material inventories.
