Since the PBC was established in 2005 by Resolution S/RES/1645, the UN has conducted periodic Peacebuilding Architecture Reviews. Previous reviews were conducted in 2010, 2015, and 2020. While the 2015 review introduced the concept of sustaining peace, the 2020 review reinforced its operationalisation across all UN activities. It reaffirmed the need for a coherent, well-funded, and inclusive approach to peacebuilding. The 2025 review is expected to build on these findings, focusing on progress made, particularly at the field level (in terms of impact and implementation), and the effectiveness of its impact in preventing and resolving conflict.

Interpeace is proud to support the 2025 Peacebuilding Architecture Review by convening and contributing to a series of consultations with civil society actors across the world. In partnership with the Initiative for International Dialogue (IID), Interpeace convened a Southeast Asia regional consultation in Manila, and in collaboration with Grupo Internacional de Paz (GIP), held a Latin America regional consultation in Medellín. These regional processes gathered critical input from grassroots peacebuilders, highlighting locally driven priorities, challenges, and recommendations to strengthen the UN’s peacebuilding architecture. The outcomes of these consultations are feeding directly into global policy deliberations in the lead-up to the 2025 Review.

In early 2025, Interpeace also convened the Geneva Consultations together with the Geneva Peacebuilding Platform (GPP) and the Swiss Federal Department of Foreign Affairs (FDFA), bringing together peacebuilding stakeholders from Geneva-based missions, multilateral institutions, and civil society. Interpeace also participated in the Policy Meeting on European Civil Society Organisations’ input to the UN Peacebuilding Architecture Review 2025, which took place in Brussels.
