01 Reduce carbon emissions
The Lufthansa Group supports the ambitious goals of the air travel industry as set for in an international statement of commitment in 2009:
• An increase of 1.5% per year in energy efficiency until 2020
• CO2-neutral growth from 2020
• A 50% reduction in net CO2 emissions by 2050 as compared to 2005
Our basis for further increases in efficiency is the industry’s accepted four-pillar strategy for climate protection. This agenda covers the entire spectrum of feasible measures.
02 Cut nitrogen oxide emissions
Since 1991, emissions of nitrogen oxides per tonne kilometer transported (g/tkm) within the Lufthansa Group have already been cut by 25.3 per cent. The Lufthansa Group supports the goal of the Advisory Council for Aviation Research and Innovation in Europe (ACARE), which envisages a reduction in nitrogen oxide emissions of 80 percent by the year 2020. This value has been calculated based on an aircraft with the most up-to-date technology this year, relative to the baseline year 2000.
03 Modernise the fleet
Green technologies will only be implemented if airlines continuously modernize their fleets. Over the next ten years, the Lufthansa Group will receive a new, fuel-efficient aircraft every two weeks on average. The CO2 savings compared with previous models will be up to 25 per cent.

04 Promote alternative fuels
Sustainable, alternative fuels with a better CO2 footprint are a key component in avoiding emissions in the future. The raw materials used may not be produced in a way that creates direct competition with the production of foodstuffs. Other conditions include a proven environmental benefit and adequate availability at an acceptable price.
The Lufthansa Group is intensively involved in various research institutions and industry associations and is constantly in touch with further developments on the subject of alternative fuels.
On 14 February 2019, Deutsche Lufthansa AG signed a letter of intent with Raffinerie Heide (Heide refinery) for the production and use of environmentally friendly synthetic kerosene. This is to be developed and produced by using surplus regionally generated wind energy in the KEROSyN100 research project under the direction of the University of Bremen with the Heide refinery and five other partners from science and industry.
05 Increase operational efficiency
Airline operations provide numerous opportunities to optimize efficiency. This includes optimum flight routings and flight speeds, efficient aircraft capacities, programs for long-term weight reductions on board and optimum aircraft loading procedures. The Lufthansa Group is steadily continuing its efforts in this field.
06 Improve infrastructure
Inefficient or insufficient infrastructure in the air and on the ground leads to unnecessary fuel consumption. It is therefore evident that airports must be expanded to keep up with demand and airspace must be used in an optimal manner. Here, policy makers in particular are called on to create the appropriate regulatory environment and introduce necessary measures in a timely manner.
07 Implementation of the global market-based climate protection instrument
Implementation of the global market-based climate protection instrument for international air transport
The Lufthansa Group has for some years now been involved in international committees working towards a market-based and competition-neutral system for climate protection fees which would be valid worldwide. Only a globally defined system can be effective in climate protection and can minimize competition distortion. At the 39th General Assembly of the International Civil Aviation Organization (ICAO) in October 2016, it was decided that the system CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) will be introduced for the compensation of CO2 emissions through project-based mechanisms. With this agreement, growth-related CO2 emissions in international civil aviation are to be compensated from 2021 by CO2 savings achieved by climate protection projects.
08 Continue offsetting carbon emissions
With Compensaid, a service developed by the Lufthansa Innovation Hub, travellers already have the opportunity, regardless of their choice of airline, to almost completely offset the CO2 emissions caused by flying by investing in Sustainable Aviation Fuel.
Since 2019, all business air travel by Lufthansa Group employees has been CO2-neutral. The CO2 emissions are offset through carbon offset projects of the Swiss foundation myclimate.
09 Develop further incentive systems
Green incentive systems, which are designed to be cost-neutral, are the right approach to ensuring sustainable mobility. Take, for example, emissions-dependent airport charges. Under this system, innovative airlines with fuel-efficient aircraft pay less, while less innovative airlines pay more. The airports in Frankfurt, Munich, Dusseldorf, Cologne, Hamburg and Hannover have already introduced such fees in relation to emissions of nitrogen oxides.
10 Reduce aircraft noise
Residents living near airports must be protected from unacceptable levels of noise. Here, too, investments in new and quieter aircraft must be the method of choice in order to achieve tangible improvements. Through continual fleet modernization and active participation in research and development, the Lufthansa Group wants to help achieve the ACARE research goal. Under the ACARE program, technologies that can reduce noise emissions by 50 per cent relative to the year 2000 are to be developed by 2020.
11 Improve aircraft
Even the noise caused by aircraft available today can be reduced. To accomplish this, it is necessary to conduct extensive research into noise sources. The Lufthansa Group, along with its partners, analyses noise-generating mechanisms and on this basis develops practicable solutions.
As part of its ongoing commitment to significantly reduce aircraft noise, the Lufthansa Group invests in state-of-the-art technology for its new aircraft and their engines and at the same time continues to optimize its existing fleet.
For example, all the A320 aircraft in the Eurowings fleet that do not yet have noise reducing vortex generators, including aircraft from the former Air Berlin, will be successively retrofitted.
12 Optimise flight procedures
The Lufthansa Group is advancing the development of low-noise flight procedures. As new flight procedures must take security aspects, capacity and efficiency into account, all the system partners – airports, air traffic control services and airlines – must pull together.
Lufthansa is involved, among other things, in testing new flight procedures (introduction of RNP RF procedures) and modern navigation technologies (GBAS) - both as part of the SESAR programme (Single European Sky ATM Research).
13 Develop comprehensive traffic concepts
Efficient transport demands that modes of transport be linked in an optimal manner. Lufthansa supports the measures required to achieve this end wherever it makes ecological and economical sense. The Company bundled its comprehensive services for intermodal travel under the brand name Lufthansa Express. The spectrum of travel options before and after a flight ranges from ICE high-speed trains to modern long-distance busses and car-sharing.
14 Build green
Conservation of natural resources also remains central to the Lufthansa Group’s planning, renovation and construction of new corporate buildings. The Lufthansa Aviation Center is exemplary in this regard.
Thanks to its thermo-active ceilings, heat-sensitive automated window-shading systems and thermally insulated facade, the administrative building at Frankfurt Airport requires significantly less heating energy than comparable buildings.
Other examples of green architecture are the new A-Plus Concourse at Frankfurt Airport and the satellite building at Munich Airport, which opened in April 2016 to increase the capacity of Terminal 2.
15 Expand environmental management
The Lufthansa Group manages its own environmental protection efforts. The Corporate Responsibility department coordinates Group-wide goals, strategies and measures. In addition, the environmental experts of the entire Lufthansa Group regularly exchange information within the framework of the internal environmental forum. Environmental management within the Lufthansa Group will gradually be systematically expanded and further developed at all levels.
