Five-pillar strategy for active noise abatement aims to reduce noise pollution

Since 2001, the Lufthansa Group has participated in research projects and implements noise abatement measures which are coordinated with relevant stakeholders. This research and development work is the basis for the Lufthansa Group’s active noise abatement. It contributes significantly to optimising both fleet and flight operations. Such measures reduce noise emissions at the source and help relieve local residents in airport regions by better distributing the remaining noise. Active noise abatement measures at the Lufthansa Group cover the following five pillars:

  • Investments in quieter aircraft
  • Noise abatement technologies for the existing fleet
  • Participation in noise research
  • Development of optimised flight procedures and routes
  • Dialogue with local residents and other stakeholders

With this five-pillar strategy, the Lufthansa Group focuses on reducing the negative impacts of noise on local communities and other stakeholders. Incidents and emergency situations are not considered relevant for active noise abatement. Consequently, the Lufthansa Group’s policies do not cover the prevention of such events.

The five-pillar strategy includes both generally effective and local activities – such as maintaining dialogue with stakeholders at key airports. Affected stakeholders include system partners such as airports, air traffic control organisations, local municipalities, dialogue platforms, noise committees, other airlines, and researchers in this field. Participation in various local committees, dialogue platforms, and expert working groups forms an integral part of the five-pillar strategy. This concept aligns with the international framework of the so-called Balanced Approach of the International Civil Aviation Organization (ICAO), which is applied at selected airports and is part of EU Regulation 598/2014 on the establishment of rules and procedures with regard to the introduction of noise-related operating restrictions at EU airports within a balanced approach.

The Lufthansa Group has a multi-airline expert committee under the direction of the Regulatory Affairs Infrastructure department, which meets regularly to discuss current operational and technical developments on the topic of active noise abatement. This committee works for the Infrastructure & System Partnerships department, which has central responsibility for managing infrastructure and system partnerships. The department is the central point of contact and representative for the Human Resources & Infrastructure Executive Board function in relation to airports, air traffic control, handling agents, regulatory and political institutions (e.g. ministries) and industry associations. As the central coordinating unit within the Group on the issue of aircraft noise, it represents the Lufthansa Group in the committees of the “Forum Flughafen und Region” in Frankfurt and supports the Lufthansa Group’s participation in various aircraft noise committees.

E2-2 - Actions and resources related to pollution

Measures to reduce aircraft noise aim to reduce the noise generated directly by the aircraft. Additionally, the Lufthansa Group seeks to better understand which activities can contribute to reducing noise pollution. Some measures affect every flight globally, while others are specifically tailored to individual sites. Dialogues with stakeholders occur particularly at the Lufthansa Group’s hubs. The measures described below are implemented continuously. Accordingly, no fixed time horizons have been set for them, except for research and development projects. Here the time horizons typically span between one and five years.

The Lufthansa Group invests in modern and thus quieter aircraft

The highest priority measure for reducing aircraft noise at source is fleet modernisation. The Lufthansa Group updates its fleet continuously. Aircraft that went into service in 2024, including Airbus A320neos, A321neos, A350-900s and Boeing 787-9s, have modern engines and are much quieter than comparable older aircraft types. The Lufthansa Group’s newly commissioned aircraft meet the noise requirements stipulated by the ICAO. For more details on fleet modernisation, please see ↗ ESRS E1 Climate change – Driving continuous investment in technological advancement.

The existing fleet is being retrofitted with noise-reducing technologies

In addition to modernising the fleet, retrofitting existing aircraft also results in measurable noise reduction. At the beginning of 2014, Lufthansa Airlines became the first airline worldwide to start operations with a new Airbus A320 equipped with noise-reducing vortex generators, thus setting an industry standard. Aircraft with vortex generators are up to four decibels quieter on their approach and so the Company pays lower noise fees in Frankfurt than for comparable aircraft without these components. All aircraft in the A320 family of Lufthansa Airlines and SWISS have now been fitted with these modifications. The retrofitting of the expanded fleet of six A320 aircraft at Austrian Airlines began at the end of 2023 and has been completed by the end of 2024. Since the end of 2023, Eurowings has equipped all its A320-family aircraft with vortex generators, which means that the entire fleet will, for the first time, be consistently fitted with this noise reduction measure in 2024. The modification is carried out in the course of routine technical maintenance cycles.

The Lufthansa Group participates in noise research to optimise approaches and take-offs

In the reporting year, the Lufthansa Group once again supported the German Aerospace Center in the ongoing development of its Low Noise Augmentation System (LNAS) for optimising approaches and take-offs. The LNAS uses aircraft data to recommend optimal configuration and speed. The German Aerospace Center is examining how approaches and take-offs can be made quieter and more efficient while observing safety regulations. Lufthansa Airlines supported the German Aerospace Center in developing the new LNAS departure functionality. The Company provided the German Aerospace Center with a large amount of flight data and additional information to improve the LNAS’ approach capabilities in the reporting year. Practical testing of the new functionality is planned to take place on the Lufthansa Airlines A330 fleet. Preparations for this began in the reporting year.

Optimised flight procedures and flight routes are developed in cooperation with system partners

Optimising the vertical flight profile (flight procedures) and horizontal flight management (flight routes) contributes to reducing noise. The Lufthansa Group is active in this area, for instance with German air traffic control (DFS) and international partners. The following example also tends to affect fuel consumption and is therefore relevant for climate change mitigation purposes.

The modern, satellite-based Required Navigation Performance (RNP) technology, which the ICAO has used to define the navigation performance required of an aircraft, plays an important role in the introduction of new flight procedures at European airports. In summer 2024, the Noise and Fuel Analyses from the first operational year of the new RNP departure route were discussed in the Aircraft Noise Commission in Stuttgart. These analyses were prepared with input from Lufthansa Airlines and Eurowings. Consequently, the Federal Supervisory Authority for Air Navigation Services decided to continue operations on the new departure route. The route is available to all airlines.

The Lufthansa Group engages in dialogue with residents near airports and other stakeholders on noise reduction measures

In addition to technical and operational improvements, the Lufthansa Group has for many years been involved in various dialogue forums with residents near airports, including in Frankfurt, Hamburg and Vienna. The experts from the Lufthansa Group contribute to the development of active noise abatement measures in these multilateral working groups. At Frankfurt Airport, Lufthansa Airlines (representing the Lufthansa Group) participates in the Noise Abatement Alliance together with the Hesse state government, Fraport AG, the Airport and Region Forum, German air traffic control (DFS) and the airline association BARIG. The airline is an influential member of the Active Noise Abatement expert panel and its sub-working groups. The focus of these activities is on optimising flight procedures and reducing noise at source. In this context, the “Forum Flughafen und Region” published the results of its study on take-off procedures in September 2024, with Lufthansa Airlines as a participant. The study found that the procedure Lufthansa Airlines uses for Frankfurt, for example, generates less noise than other methods.

The Lufthansa Group was also involved in the Alliance for Aircraft Noise Protection at the Hamburg location again in 2024. Furthermore, through its cooperation with stakeholders such as airport operators, authorities and municipalities, the Lufthansa Group participates in several flight noise committees required for major airports under the German Air Traffic Control Act and in the working group of German flight noise committees.

At many airports, the Lufthansa Group pays noise charges based on either aircraft noise certification data or its own noise measurements of individual flight movements.
