The small island nation of Nauru has launched a citizenship-by-investment program, offering “golden passports” to attract foreign investment. This initiative aims to generate funds specifically for projects designed to help the country adapt to the escalating threat of rising sea levels due to climate change. By offering citizenship in exchange for financial contributions, Nauru hopes to secure the resources necessary to protect its vulnerable coastline and infrastructure. These passports grant access to over 85 destinations globally. The program represents a novel approach to climate finance, directly linking economic opportunities with environmental sustainability. Nauru, acutely aware of its existential risk, is positioning itself as a pioneer in self-funding climate resilience. The initiative highlights the financial challenges faced by small island developing states in addressing climate change impacts.
