The International Emergency Management Organization (IEMO) is focused on underprivileged emergencies, which means forgotten or left aside areas of crisis. The philosophy of the Organization is not to act in scenarios of large "assisted" emergency, but to take care of minor and left aside crisis, normally residual for the International Community. The Organization has categorized the following nine types of emergencies as vertical section crossing the horizontal classical division among natural, man-made and complex emergencies:

Assisted Emergencies (AE) - emergencies assisted by prominent humanitarian action by the International Community, media coverage and public awareness.

Unprivileged Emergencies (UE) - emergency left aside as a whole -unitary unprivileged emergencies- or as a neuglected part of an assisted emergency.

Unitary Unprivileged Emergencies (UUE) -geographically unassisted in their totality.

Partial Unprivileged Emergencies (PUE) - partially unassisted -

Territorial Unprivileged Emergencies (TUE) - aid and recovery assistance differs in quality form a region to another

Sector Oriented Unprivileged Emergencies (SOUE) - certain specific issue is neglected (as: water sanitation in famine scenario)

Group Oriented Unprivileged Emergencies (GOUE) - a specific group is abandoned or unassisted (as: blind women in famine scenario)

Mixed/Complex Unprivileged Emergencies (MUE) - sector and group oriented issues overlap

Multifactor Unprivileged Emergencies (MFUE) - complex emergencies with territorial, sector, group and mixed factors
