This is the website of the Arms, Militarism and Climate Justice working group, an informal network of researchers and activists committed to ending militarisation of the climate crisis.

We have been meeting regularly since 2021. Since 2022, our working group has been under the umbrella of the Global Campaign to Demand Climate Justice as we seek to build stronger links between the peace and climate justice movements.

We meet every other month to share information and analysis and to collaborate on joint areas of work including events and advocacy initiatives.
