WTO has been promoting the use of sustainable tourism indicators since the early 1990s, as essential instruments for policy-making, planning and management processes at destinations. The new guidebook is the most comprehensive resource on this topic, the result of an extensive study on indicator initiatives worldwide, involving 62 experts from more than 20 countries. The new guidebook describes over 40 major sustainability issues, ranging from the management of natural resources (waste, water, energy, etc.), to development control, satisfaction of tourists and host communities, preservation of cultural heritage, seasonality, economic leakages, or climate change, to mention just a few. For each issue, indicators and measurement techniques are suggested with practical information sources and examples. The publication also contains a procedure to develop destination-specific indicators, their use in tourism policy and planning processes, as well as applications in different destination types (e.g. coastal, urban, ecotourism, small communities). Numerous examples and 25 comprehensive case studies provide a wide range of experiences at the company, destination, national and regional levels from all continents.
