At a time of heightened global instability, climate change is increasingly shaping the conditions in which peace and security efforts unfold. From pressures on land, water and livelihoods, displacement, disaster impacts and resource competition, climate-related risks are interacting with political, economic and social fragilities in ways that can exacerbate tensions, undermine governance and complicate pathways to peace and climate action across a growing number of contexts. These dynamics are already affecting many of the settings where the United Nations and its partners are engaged, at a time when resources are tightening and demands are rising.

The Climate Security Mechanism (CSM) has demonstrated that integrated cross-pillar responses to these risks are both feasible and effective.

We, the Member States of the Climate Security Mechanism Joint Steering Committee, assembled in New York on the occasion of the 2026 CSM Partnership Dialogue, call for strengthened and sustained support to the CSM with a focus on:

1. Sustaining operational presence in high-risk contexts, by providing continued and predictable support for Climate, Peace and Security Advisors deployed to UN missions and regional organizations and for the CSM core capacities, to enable localized analysis, inform activities and programming where they are needed the most.

2. Mobilizing finance for complex contexts, by supporting efforts to connect climate and peacebuilding finance with frontline needs in fragile and conflict-affected settings, advancing relevant discussions at UNFCCC COP31 and COP32, and enhancing access to climate finance, including by leveraging underutilized and emerging financing opportunities.

3. Reinforcing the CSM’s role as a proven and cost-effective model for UN coherence on climate, peace and security, bringing together four complementary entities to deliver integrated responses to complex risks without duplication, in the spirit of the leaner and more effective UN the UN80 agenda calls for.

4. Leveraging policy processes to drive implementation, by supporting the integration of climate-related peace and security risks into key national and regional policy and planning frameworks, including Nationally Determined Contributions (NDCs), National Adaptation Plans (NAPs) and peacebuilding and recovery strategies, as a means to strengthen implementation, and connect policy priorities with financing opportunities.

5. Broadening partnerships on climate, peace and security by actively encouraging UN Member States, regional organizations, knowledge and other partners not yet engaged to join relevant processes, share analysis and good practices and advance coordinated approaches across multilateral, regional and national processes.

We urge UN Member States, regional organizations and partners to join this effort and to support the scaling of the CSM, including through renewed, expanded and multi-year political, technical and financial contributions to sustain the CSM’s work at the scale the current moment demands.
