Over 1000 leaders and practitioners from 88 countries convened in Manila, Philippines, at the 6th International Conference on Tourism Statistics: Measuring Sustainable Tourism (21–23 June 2017). Ministers, Statistical Chiefs, policy experts, statisticians, private sector and academics dedicated to sustainable development and tourism united to lay the groundwork for an expanded statistical framework for Measuring Sustainable Tourism (MST) in its economic, social and environmental dimensions. Global leaders spoke strategically, and politically, on the need for statistics to credibly substantiate tourism in national and international agendas, and as a lever for sector viability. The outcome "Manila Call for Action on Measuring Sustainable Tourism" represents a global commitment to sustainable tourism and the need to measure it through a consistent statistical approach, recognizing that effective sustainable tourism policies require an integrated, coherent and robust information base.
