Tourism-related carbon dioxide (CO₂) emissions are a central driver of anthropogenic climate change. At the same time, climate change has both direct and indirect impacts on tourism, varying from damages of tourist assets due to extreme weather events, to losses of biodiversity. Small island developing states (SIDS) heavily depend on international tourism as a source of revenue and income. Therefore, much could be gained by assessing the vulnerability of the SIDS tourism sector and by identifying measures that may assist these islands in their sustainable adaptation efforts. Against this background, this interdisciplinary paper provides a review of tourism development and the implications of its emissions on the global climate, linked with observed and projected influences of climate change in the Pacific region, to explain the growing vulnerability of the overall sector, with a particular focus on SIDS tourism. A description of the effects of COVID-19 on international tourism and its consequences for SIDS complement the analysis. Case studies of two Pacific islands present some evidence of current climate impacts, underscoring the multiple risks small island nations and their tourism sectors face. The paper concludes by stating that some measures may be prioritized by decision-makers, so as to increase the resilience of a transforming tourism sector in SIDS.

Small Island Developing States (SIDS) are heavily dependent on the use of imported fossil fuels to address their energy needs. This has a negative impact on the environment, SIDS budgets, and energy security. Therefore, this study aimed to investigate the role of renewable energy (RE) as a tool for energy security in SIDS. In this regard, using VOSviewer, a widely known software tool, two bibliometric analyses were performed with a focus on the literature that explores two intertwined issues: (i) the links between RE and energy security; and (ii) the implications of RE and energy security in SIDS. The results from the study show that RE can help SIDS enhance their energy security and assure long-term energy sustainability. In addition, the results show that with the reduction in the cost of batteries in the future, they will eventually replace diesel generators. Moreover, the study showed that renewable energy may assist SIDS in their long-term efforts to achieve food security. The analysis discusses the major obstacles and the potential solutions for the integration of RES into the energy generation of SIDS. The paper concludes with useful recommendations to help island nations reduce their carbon footprint.

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.
