Climate Security Research Programme

This programme of work addresses climate change as the backdrop to all national security, defence and foreign policy discourses.


As part of RUSI’s Climate Security programme, we undertake research and host events focusing on the impact of the current climate emergency on the global security and defence realms. With expertise across a range of themes and geographies, our researchers are exploring both the existing and future challenges of global warming.

We explore how climate change intersects with ‘traditional’ security challenges at the local, regional, institutional and international levels, through themes such as: Greening Defence; Environmental Crime in a Warming World; Climate and Environmental Activism; Energy Security; Securing Net Zero Technologies; and Climate, Energy and Security in the Middle East.

The Climate Security programme rests on the fundamental assumption that climate change is both an existential threat to humanity and a threat multiplier. The programme brings together stakeholders from across government, academia, the private sector and civil society to advance cross-sectoral dialogue and offer policy-relevant recommendations to decision-makers.

Programme themes
