“Tourism is not just at risk from climate change. It is also one of the factors driving it, and it is a significant contributor to emissions growth. By 2030 there are projected to be 1.8 billion international visitor arrivals, an increase of over 3% a year from 2010, not to mention the billions more who travel domestically. Tourists are also travelling further than ever before and by more energy-intensive means of transport. Almost all the energy used in tourism is derived from fossil fuels. Transport is the main contributor to tourism CO2 emissions – with flying accounting for 40%, car transport for 32% and accommodation for 21%. One scenario estimates that emissions from travel and tourism will increase by 169% by 2050 if no action is taken.”
These are initial information you can find within the report TOURISM AND CLIMATE CHANGE MITIGATION EMBRACING THE PARIS AGREEMENT:PATHWAYS TO DECARBONISATION.
The report commissioned by the European Travel Commission provides a first global analysis of the risks to the tourism industry from climate change. While it draws on high-level climate change expertise, it also contains the views and experiences of 17 travel and tourism leaders, who acknowledge that the viability of some destinations is seriously threatened, and investigates ways in which tourism can become part of the global solution to tackle the risks of climate change.
The research was published in March 2018 and is available for free download.
