Natural disasters continue to pose serious threats, causing significant damage and loss of life. The involvement of Filipino internationally educated nurses (IENs) has become increasingly important for effectively managing and responding to such crises. Although the healthcare industry plays a central role in disaster management, the specific contributions of IENs in this context have not been thoroughly examined. Additionally, the environmental implications of IEN recruitment point to the significance of their engagement in climate mitigation. Leveraging the HEAL Model—Help, Educate, Act, and Lead—IENs play crucial roles in training officials, educating peers, leading environmental initiatives, and advocating for policy changes. Their collaboration with volunteers during disaster situations underscores their effectiveness. The IENs, in collaboration with volunteers, bring substantial contributions to disaster nursing and are showcased through the HEAL Model, signifying their potential for enhancing disaster response and climate action endeavors.
