The objective of this study is to propose strategies and mechanisms to help sustainable tourism certification programs achieve long-term financial viability. The study looked at financial models and mechanisms used by certification program from other industries (such as organic produce and forestry) and from various tourism certification programs from around the world. We examined seven non-tourism certification programs and one non-tourism accreditation program to determine which experiences were applicable to tourism. In addition, 33 tourism certification programs working in the United States, Latin America, Europe, Asia-Pacific and Africa were evaluated to examine their financial structures and strategies, as well as listen to their recommendations. Representatives of 12 funding bodies and two non-governmental organizations (NGOs) supporting sustainable tourism or green certification in the United States, Latin America, and Africa were also interviewed to determine their funding priorities and interests; find out what types of relevant projects and programs they have supported; and elicit recommendations for how to help sustainable tourism certification and accreditation bodies become more financially sustainable.
