Should governments treat climate change as a core national security priority?
At New York Climate Week, the UK Foreign Secretary identified climate change and nature loss as urgent national security threats. The government plans to leverage its embassy network to boost international climate cooperation.
Why it matters
The Foreign Secretary argues that dependence on fossil fuels creates critical economic and energy security vulnerabilities. By elevating these risks, the UK intends to treat environmental stability as a foundational pillar of its national security strategy.
Global clean energy investment hit $2.2 trillion in 2026, significantly outpacing the $1.2 trillion directed toward fossil fuels. Meanwhile, 150 million hectares burned globally during the first four months of the year.

Deeper Dive
This policy pivot follows the established benchmark of the UK's 2030 clean power system goal, signaling an expansion of environmental strategy beyond energy infrastructure into national security architecture.
The push for a clean energy transition may accelerate the development and availability of new sustainable technologies globally. These shifts could eventually lead to lower energy costs for consumers as the fossil fuel dependence decreases.
The takeaway
