The aim of this research was to analyze empirically environmental carrying capacity in three islands – Jeju (Korea), Hawaii (USA), Tasmania (Australia) in terms of Environmental Impact (EI) and Ecological Footprint (EF) – on a comparative basis. The three islands experienced change in EI for ten years from 1996 to 2005, showing a trend of increase from 1996 to 2005. Hawaii was highest in the increase, showing 2.729 times, and followed by Jeju (2.129 times) and Tasmania (1.719 times). Jeju exceeds EF size by 15.14 times, Hawaii by 2.55 times, and Tasmania by –8.088 times. Jeju islanders require 2.044 earths, while Hawaii and Tasmania islanders require 2.239 and 2.585 earths, respectively. The size of EF the islanders occupy was different by the demographic and socio-economic profiles in each of the three islands. The factors impacting on the determination of EF size was also different by island. Such differences in EI and EF by island might be caused by many factors. ‘What factors arises such differences’ is another research question to be conducted. Another limitation inherent in this research is that the data used are confined to particular period of years the three islands experienced. This means that this research is based on a limited number of parameters, and measurement instrument has been partially developed. To determine EI and EF, assumptions would have to take into account a long list of parameters. Further development of this model will prove useful for policy formation and management for sustainable development within environmental carrying capacity.
