Renewable energy investment should come from defence budgets, say retired military leaders

Former European officers say spending on low-carbon power would make nations more resilient to threats from potential aggressors

Investment in renewable energy should be counted under defence expenditure, says a group of retired senior military personnel, because the climate crisis represents a threat to national security.

They have called for increased spending on low-carbon power as a way of making the UK and other European countries more resilient to threats from Russia and other potential aggressors.
