Developing a global tourism scenario that achieves 50% reduction of greenhouse gases by 2030 and zero by 2050.
In the Glasgow declaration (2021), the tourism sector pledged to reduce its CO2 emissions by 50% and reduce them to zero by 2050. But how to achieve these goals? This scenario-study provides the answer.
Emissions from accommodation, the private car and rail and busses will reduce under the Paris Climate Agreement. But aviation’s emissions are exempt and hard to abate, but up to 2050, sustainable synthetic e-fuels, fuels made from captured CO2, combined with a global stop on the growth of aviation until 2050, cannot anymore be avoided. After 2050, new aircraft flying on hydrogen and fuel cells/electric engines, allow for a regained air travel growth. The good news is that the total number of tourism trips, nights and the total tourism economy can grow as in a business-as-usual scenario. Only the distances we travel will grow at a slower pace until 2050.
