Training: Climate-Environment-Security and Defence Nexus

15 - 18 June 2026
Brussels, Belgium

Climate change and environmental degradation are reshaping the security landscape. Integrating a climate and environmental security perspective into policy and operations is no longer a peripheral concern – it is a strategic imperative. Organised by European Security and Defence College (ESDC) and adelphi global since 2018, this upcoming training aims to equip participants with the needed knowledge, tools, and skills for navigating the clmate-environment-security and defence nexus, using a blended methodology approach.

Overall Aim

The primary objective of the training is to equip participants with the essential knowledge, tools and skills required to integrate a climate and environmental security perspective into their day- to-day work. Specifically, by the end of the course, participants are expected to be capable of applying a climate and environmental security perspective within their area of expertise.

It will cover:

  • Core concepts and principles of climate security
  • Climate literacy and raising awareness of the impacts of climate
    change, environmental degradation and exploitation on peace, security, and defence
  • The role of climate change and environmental degradation as threat multipliers – and as enablers of peacebuilding
  • The integration of climate and environmental considerations across CFSP/CSDP processes
  • The EU's approach to the climate-security nexus and coordination with internal and external stakeholders

Learning outcome

Knowledge outcomes: 

  • LO.1. Explain the concept of planetary boundaries, including key climate change trends - causes, risks, hazards, environmental degradation and exploitation, using different scenarios and impact analysis. 
  • LO.2. Understand the complex relationship between climate change, environmental degradation and exploitation, and security, including how these factors potentially provide opportunities for strengthening international, regional or local peace and security. 
  • LO.3. Explain the relevance of a comprehensive climate and security approach (adaptation and mitigation) for a sustainable European security and defence, including CFSP/CSDP. LO.4. Recognise key crosscutting issues in climate and environmental mainstreaming, such as human rights, gender responsiveness, protection of civilians, good governance principles, and building integrity. 
  • LO.5. Describe the key international policy frameworks and actors involved in the climate-security nexus, with a special emphasis on the EU and the EU-wide comprehensive framework for addressing climate and environment-related security risks. 

Skills outcomes: 

  • LO.1. Use evidence-based analysis and foresight to support climate and environment informed planning, decision-making and implementation (monitoring and evaluation), particularly within the CFSP/CSDP contexts, by taking into account cross-cutting issues like human rights, gender responsiveness, protection of civilians, good governance principles, and building integrity. 
  • LO.2. Apply analytical and problem-solving skills to address climate and environmental challenges and opportunities in a specific context. 
  • LO.3. Integrate an environmental lens into guidelines, tools, frameworks to ensure climate- and environmental-sensitive analysis, planning, decision-making and implementation.
  • LO.4. Identify potential responses and mechanisms to support climate resilience, emphasizing preventive measures, including within peacebuilding efforts.
