Revealed: Nato rearmament could increase emissions by 200m tonnes a year

Exclusive: researchers say defence spending boosts across world will worsen climate crisis which in turn will cause more conflict

A global military buildup poses an existential threat to climate goals, according to researchers who say the rearmament planned by Nato alone could increase greenhouse gas emissions by almost 200m tonnes a year.

With the world embroiled in the highest number of armed conflicts since the second world war, countries have embarked on military spending sprees, collectively totalling a record $2.46tn in 2023.
