What Rising Defence Spending Means for Climate Action
As global defence budgets surge in response to rising geopolitical tensions, climate innovation is being pulled into a new political and economic order. Technologies once developed for net zero are now being rebranded under the banners of resilience and strategic autonomy, while public and private capital increasingly flow toward dual-use and frontier applications.
This Earth Set panel explores the complex intersections between climate, security and innovation — asking what’s really shifting, what’s being rebranded, and how the UK should respond. Are climate and defence on a collision course, or can a new synthesis emerge?
Confirmed speakers:
Hetti Barkworth-Nanton CBE, CEO of Ploughshare Innovations
Adam Bell, Director of Policy at Stonehaven, former Head of Energy Strategy at BEIS
