The travel group has set binding targets for the airlines, hotels and cruise ships by 2030. For Tui airlines, which account for around 80 percent of the group's own emissions, emissions are to be reduced by 24 percent by then compared to 2019 levels. In the hotel segment, there is to be a reduction of at least 46,2 percent and for cruise companies by 27,5 percent. Plans include investments in modern aircraft, energy savings in all areas, the promotion of local purchasing for hotels and the use of sustainable fuels for cruise ships. Tui is also sticking to its previously set goal of offering climate-neutral cruises by 2030 at the latest, according to the German online portal Aero. In view of climate change, the travel industry is being criticized by environmentalists because air travel and cruises, among other things, cause high emissions of climate-damaging greenhouse gases.
