Aviation accounts for over 80% of our carbon footprint, and our focus is therefore on reducing the climate impact of our TUI airlines. We already run the most carbon-efficient airlines in Europe, have a strong history of backing new, carbon-saving technologies, and support progressive climate policies for aviation. 

In 2016/2017, TUI airlines’ relative carbon emissions were 66.7g per revenue passenger kilometre (gCO2/RPK).

Boeing 787 Dreamliner

We fly Europe’s largest Boeing 787 Dreamliner fleet, which emits around 20% less CO2 per passenger kilometre than comparable aircraft. It also produces up to 60% less noise pollution. We currently operate 14 Boeing 787 Dreamliner planes, expanding it up to 17 aircraft until 2019.

Split scimitar

Currently fuel-saving blended winglets are fitted to 97% of our aircraft, reducing fuel burn by up to 5%.We were the first in Europe to use the new innovative split-scimitar winglets, reducing fuel burn by up to an additional 2%. On a flight from Hanover to Boa Vista (Cape Verde) this new aerodynamic flow system is able to save up to 450 litres of kerosene.

Engine wash

A regular engine wash reduces the specific fuel consumption by 0.7% directly after the wash, resulting in a total saving of about 0.3% over the year. By this means our aircraft are able to save up to a 1,000 tons of CO2



757 eco demonstrator
757 ecoDemonstrator

NASA, Boeing and the TUI Group pooled their innovative strengths and collaborated on a scientific project. The test flights with the „ecoDemonstrator 757“ evaluated new technologies to improve aviation’s efficiency and reduce noise and carbon emissions.


More fuel efficiency examples:

  • High passenger load factors (we ensure that each flight is as full as possible)
  • Operational efficiencies such as single-engine taxiing, continuous descent approaches and optimised flight planning
  • Reducing weight on our aircraft through lighter catering trolleys, lighter seats and optimising the amount of water and goods we carry on board
  • Maintenance efficiencies such as lighter paint and surface sealant applications that reduce drag on the aircraft by stopping dirt and grime adhering to it
  • Implementation of an enhanced fuel monitoring and management system in four airlines
