Climate change is one of the greatest global challenges facing the international community. Aviation accounts for over 80% of our carbon footprint, and our focus is therefore on reducing the climate impact of our TUI airlines. In 2017/2018, TUI airlines’ relative carbon emissions were 66.7g per revenue passenger kilometre (gCO2/RPK).

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. But we will continue to focus consistently on reducing airline emissions, also through the renewal of our airline fleet. TUI Group was the first tourism group to launch the Boeing 787 Dreamliner aircraft to its fleet. The Dreamliner consumes around 20% less jet fuel than comparable aircraft. With the Boeing 737 MAX, we will have 72 new and 14% more efficient and quieter aircraft in our fleet by 2023. In addition, all TUI holiday airlines are certified according to the internationally recognised ISO 14001 environmental standard.

Fleet renewal

In order to continue operating Europe's most emission-efficient airlines, we will continue to modernize our fleet. We fly Europe's largest Boeing 787 Dreamliner fleet, which emits up to 20% less CO2 emissions per passenger kilometre than comparable aircraft. It also produces up to 60% less noise pollution. By 2019 the fleet will grow to 17 Dreamliners. Since January 2018 the newest Boeing 737 MAX 10, the largest member of the Boeing 737 family, has been part of the TUI fleet with higher fuel efficiency. In the coming years, a total of 18 737 MAX machines will modernize the fleet.

757 eco demonstrator
757 ecoDemonstrator

NASA, Boeing and the TUI Group have combined their innovative strength in a scientific project. The aim of the flight tests with the „ecoDemonstrator 757“ was to evaluate new technologies to improve aviation’s efficiency and reduce noise and carbon emissions. Environmental technologies such as the Krueger shield and the bug-phobic wing coatings were tested on the wings, which improve the aerodynamic effect an thus reduce flow resistance. At the end of the flight series, the recyclability of the ecoDemsonstrator was tested in order to develop an environmentally compatible standard procedure for future aircraft disposals. A total of 90% of the aircraft could be recycled.  

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.

Biofuel – Aviation fuels of the future

TUI’s top priority remains to continue to reduce fuel consumption until sustainable fuels become commercially viable in both economic and qualitative terms. We are engaged in industry initiatives and research programmes such as the Sustainable Aviation Fuel Users Group to help scale up sustainable aviation fuels of the future. TUI Aviation joined the Bioport Holland, a public-private sector initiative, to work jointly towards continuous production, supply and dissemination of sustainable bio jet fuel for the Netherlands and Europe. In early 2018. TUI started to take delivery of the new 737 MAX aircraft. The 30 percent share of biofuel enables a significant increase in CO2-efficiency. TUI is working on a sustainable fuels strategy to identify opportunities for TUI Airlines to support the development of sustainable aviation fuels supply chains.

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
