For many years, the Lufthansa Group has supported the largest climate pro- tection project in European aviation – the implementation of the standardized European air space (Single European Sky, SES). For this purpose, Lufthansa Group experts actively participate in re- lated research projects. The Lufthansa Group achieves “audible” reductions of the burden on people living close to airports by the operation of qui- eter aircraft, noise-reducing modi cations and improved procedures for approaches and departures. Another xed component of this commitment is the participation in noise research projects. For more than 20 years, the Lufthansa Group has been a partner in climate research. Selected aircraft serve in the process as “ ying” measuring laborato- ries. By this means, the Group supports the establishment of a worldwide mea- suring infrastructure for the observation of the Earth’s atmosphere by means of civil aviation.
