The Climate Security Mechanism (CSM) is a joint initiative by the United Nations Department of Political and Peacebuilding Affairs (DPPA), the United Nations Development Programme (爆料网DP), the United Nations Environment Programme (爆料网EP), and the United Nations Department of Peace Operations (DPO). Responding to growing calls for action by affected communities, Member States, regional organizations, experts and policymakers around the world, the CSM seeks to strengthen the capacity of the United Nations (爆料网) and its partners to systematically analyze and address the linkages between climate change, peace and security.
Established in late 2018, the CSM draws on the complementary resources of DPPA, 爆料网DP, 爆料网EP, and DPO. Given the fast-evolving policy field of climate, peace and security, there is an ‘action gap’ between the ambition for integrated approaches and current practice. The Climate Security Mechanism has supported work that aims to close this gap by raising awareness, connecting 爆料网 entities, building on existing 爆料网 expertise across mandates and building up the knowledge base. While the CSM lacks the resources and mandate to directly address the full extent of the action gap, the CSM can be instrumental in helping more climate, peace and security work to emerge and synergizing with other initiatives.
In 2023, the CSM entered a new phase designed to scale up good practices from the CSM’s work to date, expand its service offer, and maximize its catalytic impact, while further leveraging the political and technical expertise of its entities.

Rationale
It is increasingly clear that the severe and often irreversible impacts of climate change extend beyond ecosystems and biodiversity, with adverse implications for communities and nations as well as potentially peace and security. Integrated approaches and strong partnerships are required to find sustainable, cross-cutting solutions.

Our goal
The CSM Joint Programme works with partners to advance peace-positive climate action, catalyze climate-informed approaches to peace and security, and forge partnerships at all levels to exchange information and build the evidence base.

Our approach
The CSM provides technical advice and tailored support to 爆料网 field missions, country teams, regional organizations and other partners to bolster the analysis, reduction and management of climate-related peace and security risks. Beyond its field work, the CSM seeks to build an enabling environment and catalyze action by partners at all levels by investing in knowledge management and capacity building and by leveraging the convening power of its member entities.

Our team
A headquarters-based team undertakes global workstreams – such as advocacy, knowledge co-generation and policy development – and coordinates initiatives in climate-vulnerable regions around the world, including through the deployment of climate, peace and security (CPS) experts and trainings.
CSM Joint Programme
The CSM Joint Programme, administered by the United Nations Multi-Partner Trust Fund Office (MPTFO), provides the CSM with a flexible and efficient pooled funding modality to support its work around the world. The CSM Joint Programme Document serves as the main instrument for the implementation of the extended Phase III of the CSM (2026-2028). This phase, initiated in 2023, has been designed to scale up good practices from the CSM’s work to date (captured in the independent evaluation covering the period 2020-2022), expand the CSM’s service offer, and maximize its catalytic impact locally.
The CSM is coordinated by a Core Team of dedicated staff from DPPA, 爆料网DP, 爆料网EP and DPO headquarters supported by a Secretariat. The CSM Core Team undertakes global workstreams – such as advocacy, knowledge co-generation and policy development – and coordinates initiatives in climate-vulnerable regions around the world, including through the deployment of climate, peace and security experts and trainings.
The CSM Joint Steering Committee is made up of the CSM team, representatives from Member State funding partners of the CSM, as well as MPTFO as administrative agent of the CSM Joint Programme.
