This report provides an overview of the increasing vulnerability of World Heritage sites to climate change impacts and the potential implications for and of global tourism. It also examines the close relationship between World Heritage and tourism, and how climate change is likely to exacerbate problems caused by unplanned tourism development and uncontrolled or poorly managed visitor access, as well as other threats and stresses. The report’s goal is to provide up-to-date information and a basis for action on climate change, tourism and World Heritage in the followup to the adoption of the Paris Agreement by the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in December 2015 and the 2030 Agenda for Sustainable Development, adopted by the United Nations General Assembly in October 2015.
