For a defence manufacturer, energy security isn’t just a cost line — it’s a strategic one. BAE Systems shares how geopolitical shocks are rewriting the economics of its transition, why insulating from price volatility is mission-critical, and how it’s pulling a 17,600-strong supply chain along with it.

• How war reprices the transition: with EU gas hitting 5x US levels and prices swinging on events in Ukraine and the Middle East, does volatility make the case for self-generation stronger, or harder to finance?
• Energy security as a strategic priority: for a critical manufacturer, a price shock is a risk to output. A deep dive into how BAE is building resilience — targeting 90% renewable electricity by 2030 and deploying new tech like on-site solar.
• The supply chain gap: BAE can afford to decarbonise; many of its suppliers can’t. With 20–30% of defence emissions sitting upstream, how do you move an SME-heavy chain?
