The intention of the original signatories of this White paper was to create a living document, guiding a way forward for a national discussion on mitigation. The names of the 16 organizations on the original paper signify those who developed the ideas found in the subsequent pages, but do not represent a comprehensive list of organizations dedicated to the continuation of the mitigation discussion. Since the release of the white paper in 2009, numerous groups have indicated their intention to endorse and further support the concepts within the paper and possible actions taken by the collective signatories.
