Global Military Advisory Council on Climate Change (GMACCC)


Created in 2009 as a response to threats posed by climate change towards global security and peace GMACCC was created based on the initiative of the Institute for Environmental Security (IES). GMACCC is a global network of serving and retired military officers, and associated institutions, committed to highlighting the potential security implications of a changing climate and advocating action, including by the military, to minimize the risks. By calling upon the military to reduce their energy use GMACCC aims at achieving a reduction in their contribution to climate change.
