“…Using the approach of the International Union for Conservation of Nature [66], these 30 selected countries/destinations are defined as sustainable due to their high socioeco-nomic performance and low environmental pressure footprint, presenting an overall score of more than 65% on the sustainable development index (65-75% as strong sustainability indicator, while 75-85% as very strong sustainability level) [78]. Moreover, based on Tran and Rudolf's recent research that spotted the majority of sustainable destinations to be concentrated firstly in Europe and Asia [79], 22 of this sample's sustainable destinations are in Europe (Finland, Denmark, Sweden, Norway, Austria, Germany, France, Switzerland, Ireland, Estonia, United Kingdom, Poland, Czech Republic, Latvia, Slovenia, Spain, Netherlands, Belgium, Portugal, Hungary) while the remaining eight are located in Asia (Japan, Republic of Korea, Singapore, New Zealand, Thailand, Vietnam, China) as presented in the Sustainable Development Report Rankings 2022 [77].…”
