Montreal Climate Security Summit 2025

About
The NATO CCASCOE and the Conference of Defence Associations (CDA) Institute are proud to announce the 4th Montreal Climate Security Summit, which will take place on October 8-9, 2025, in Montreal, Canada.
The Montreal Climate Security Summit is an annual international meeting at the intersection of climate change and security, serving as a key venue for the global climate security community. It brings together military and civilian practitioners, policy leaders, researchers, civil society and industry stakeholders.
This year’s edition will focus on strengthening military adaptation in the face of climate risks, including technical, scientific, and operational discussions exploring how armed forces can plan and execute activities across all domains in an operational environment shaped by climate change. The Summit will span over two days and will feature a mix of plenary panels, roundtables (up to 80 participants) and workshops (up to 50 participants) designed to further strengthen cross-sectoral dialogue across the community of interest, foster solutions-oriented discussions, and drive actionable outcomes.
This year’s Summit will be in-person and by invitation only.
However, the event will have a limited number of additional seats reserved for students and members of the general public who are passionate about the intersection of climate change and security.
If you are interested in attending as a guest, please submit your statement of interest form.

About the Organizers

The 4th edition of the Montreal Climate Security Summit is co-hosted by the NATO Climate Change and Security Centre of Excellence (CCASCOE) and the Conference of Defence Associations (CDA) Institute, building on the successful partnership initiated with the 3rd edition, in 2024.
The first two editions of the Summit were led by the CDA Institute. With the establishment of the CCASCOE in Montreal in 2023, the two organizations have joined forces to build on previous efforts and generate a landmark venue to discuss climate security between NATO Allies and beyond.
The Conference of Defence Associations is a leading defence and security think tank founded in 1932, which brings together 45 member associations representing over 400,000 active and retired members of the Canadian Armed Forces and Canadians with a close connection to national defence and security.
In 1987, the CDA founded a separate Institute as a charitable organization with the mission to advance informed debate on national security issues. As the first dedicated programme in a Canadian defense think tank, the CDA Institute’s Climate Security Programme positions the Institute at the forefront of efforts to understand and address the complex intersections between climate change and Canadian security and defence - including operational readiness, geopolitical risks, and societal resilience. Through its activities promoting expertise, research and analysis on the climate-security nexus, the Climate Security Programme aims to: inform the national debate and Canada’s role in global policy efforts on climate security; strengthen the Canadian climate-security community of practitioners, scholars, policymakers and industry stakeholders; advance interdisciplinary approaches to climate security; and support the development of practical solutions to mitigate and adapt to the emerging defence and security challenges shaped by climate change.
The CCASCOE is the 30th NATO Centre of Excellence. Canada, the framework nation, was joined in contributing to this centre by Denmark, France, Germany, Greece, Italy, Latvia, Luxembourg, Norway, Romania, Türkiye and the United Kingdom. Its opening in October 2023 and its accreditation to NATO in May 2024 represent milestones to address the implementation of the NATO Climate Change and Security Action Plan and contribute to NATO’s overall military readiness, deterrence and defence posture. To achieve its objectives, CCASCOE’s mission is based on four pillars: Increasing Allied awareness of the security implications of climate change; Adapting to the impact of climate change across NATO and beyond; Mitigating NATO’s impact on climate change while preserving and strengthening our military effectiveness and interoperability; and Conducting outreach and strengthening cooperation with a wide range of stakeholders. CCASCOE aims to be an internationally recognized hub of expertise on climate change and security for military and civilian experts and decision-makers.
What to Expect
Participants are encouraged to bring their expertise and experience to bear on the conversation. The event is designed to foster interdisciplinary dialogue and facilitate the ideation of solutions. It is an opportunity to engage with our speakers and ask questions that break out traditional disciplinary and policy silos.
Programme Overview
The Summit will span two days and will feature a mix of plenary panels, roundtables (up to 80 participants) and workshops (up to 50 participants) designed to further strengthen cross-sectoral relationships across the community of interest, foster solutions-oriented discussions, and drive actionable outcomes. Through these discussions, we aim to support armed forces in enhancing resilience, operational effectiveness, strategic readiness, and force projection.
Plenary sessions and keynote speeches will contribute to the common understanding of the current state of climate security and the main challenges and opportunities for the coming decades. Roundtables and workshops will be led by the event organizers (CCASCOE and the CDA Institute) and external partners. This collaborative approach will ensure that each session is informed by leading expertise and a diversity of practical experience from across the climate security community.
