With the adoption of the 17 SDGs in September 2015, the High Level Political Forum (HLPF) was appointed as the United Nations body for the review of the 2030 Agenda for Sustainable Development. During the last, annual HLPF, a cyclical review system was consolidated, composed of two main mechanisms: (i) [global] thematic reviews and (ii) national voluntary reviews (NVRs). Thematic reviews were agreed under Resolution A/70/L.60, also approved during the last HLPF. It was agreed that the next three HLPF meetings would have specific themes, with a set of associated SDGs to be reviewed. Against this backdrop, the HLPF review process will benefit greatly if there is an opportunity for governments and stakeholders to review and synthesize information ahead of the HLPF. This would facilitate the processing of information and contribute to the thematic reviews. To maintain coherence with the official process, exercises of this type should to be conducted following important principles of the 2030 Agenda, demonstrating, in practice, how to pilot a thematic review.
