This tiny Pacific island is offering citizenship for $90,000, but there's a powerful climate reason behind its 'golden passport' programme

Naoero, previously known as Nauru, has introduced a program that offers citizenship to individuals contributing to climate adaptation funding. The initiative focuses on securing finances necessary for relocating vital infrastructure and families further inland, in response to the increasing threats posed by rising sea levels and coastal flooding. Those who successfully navigate the rigorous application process receive a passport, emphasizing the growing trend of seeking second citizenships worldwide.
