Tourism resembles an indispensable source for financing national development and securing local livelihoods in Small Island Developing States (SIDS) with their sun-sea-sand tourism. Related carbon dioxide (CO2) emissions counteract sectoral development as climate impacts have begun to severely reduce the attractiveness of destinations. This is valid especially for disaster-prone SIDS where slow and rapid onsetting phenomena and severe, frequent weather events are already experienced, increasingly putting tourist assets, infrastructure, local livelihoods and unique biodiversity under pressure. Against this background, this review synthesizes the recent climate change and tourism literature relating to main SIDS regions, highlighting what is at risk. The authors provide latest evidence of the role tourism plays for these islands and elaborate the peculiar climate risks, impacts and consequences for tourism development. The current state of adaptation is explored and research priorities in SIDS regions are highlighted. Whereas SIDS show high mitigation ambition, the significance of CO2 emissions along the value chain and especially related to the transport to SIDS destinations remains a problem that developed nations must address in their national emission reduction plans. Further research at the interface of climate change and tourism is needed, contributing to the decarbonisation of tourism and successful adaptation in SIDS. [ABSTRACT FROM AUTHOR]
