Small Island Developing States (SIDS) present a group of small island countries that tend to share similar sustainable development challenges, which except from small, but growing populations, limited resources, and extensive dependence on international trade, include remoteness, sensitivity to natural disasters and vulnerable environments. For these islands climate change is an everyday reality and nowhere in the world are its implications more immediate than on SIDS. This particularly includes sea level rise, contaminated water, increased coral bleaching, rise of the global average temperatures, high levels of unemployment and consequently brain drain and other migrations. The paper focuses on three distinctive geographic regions by analyzing climate challenges of following SIDS: Barbados (the Caribbean), Seychelles (Africa) and Tuvalu (Asia and Pacific). Although aforementioned states share similar destiny as a result of smallness and remoteness, as well as most of the climate challenges, at the same time they display completely different policies in addressing them. While Tuvalu is SIDS most affected by climate changes which endanger its survival and is mostly focused on preserving its statehood, Barbados and Seychelles are more prone to concrete policy responses by promoting renewable energy and blue economy.
