RedR (pronounced 'Red R') is an international NGO whose stated mission is to “rebuild lives in times of disaster by training, supporting, and providing aid workers to relief programmes across the world.” It was originally an acronym for Register of Engineers for Disaster Relief, although it is no longer used as such. They further help to ensure that skilled professionals are always available to respond to major global emergencies through an aid worker recruitment service and by advising and training potential new relief workers.
