While there is a broad consenus that the governing structures energing from the Post-2015 Agenda should encompass a review system in order to ensure its credibility, the principles underlying such a system as well as details of its implementation still need to be agreed on. Civil society and think tank representatives from around the globe as well as representatives of governments met in Berlin, Germany, on May 6, 2015 to discuss prospects for a review of the Post-2015 Agenda and goals for sustainable development. According to the chair’s conclusions, the participants agreed that monitoring and reporting are crucial parts of this policy learning process and that a multi-level review process needs to be designed to that purpose. Such a review process should be voluntary and supportive, but most importantly led by nation states, which requires transparency and participation in order to increase ownership and accountability. The review mechanism should also be a platform for partnership and stakeholder engagement.
