The Sustainable Tourism Index by The Economist Intelligence Unit

“The Sustainable Tourism Index assesses countries on their commitment to develop and promote sustainable practices in tourism. It finds that, not surprisingly, the world’s developed countries have done more at the national level than their emerging-world rivals to formulate policy, foster adherence to recognised standards, encourage travel and tourism businesses to reduce their environmental footprint, co-ordinate efforts with NGOs and the private sector, and ensure protection of their cultural and historical assets.”
