Sustainability Report Balance // Issue 2015 // Lufthansa Group // 107 their greenhouse gas emissions and their climate protection strategies transparent. For this purpose, the CDP and its partners jointly developed two indices: the Carbon Disclosure Leadership Index, which includes companies that make their emissions trans- parent to a particular extent, and the Car- bon Performance Leadership Index, which takes concrete climate protection achieve- ments into account. Chapter 4 aircraft Aircraft that comply with the strictest noise protection standard currently in force – the Chapter 4 noise standard. The Environ- mental Committee (CAEP) of the ICAO agreed on this standard in September 2001. As a result, all aircraft newly certified since 2006 must remain cumulatively below the Chapter 3 noise levels by 10 decibels or more. The maximum noise emission values for aircraft were introduced by the ICAO under Annex 16 to the Con- vention on International Civil Aviation. Noise levels depend on the aircraft’s maximum takeoff weight and number of engines. CO see “Carbon monoxide” CO2 see “Carbon dioxide” Codeshare A codeshare is a flight segment that is sold under the flight number of one airline while being operated either partly or entirely by another airline. Both companies maintain their independent profiles in the market. Compliance Compliance describes in their entirety all measures that ensure the lawful conduct of companies, their management bodies, and their employees with regard to legal direc- tives and interdictions. Corporate Responsibility (CR) Corporate responsibility expresses the degree to which a company assumes accountability for the effects its business activities have on employees, customers, society, and the environment. D Decibel Measuring unit for the intensity and pres- sure of sound. The difference in intensity between the softest sound the human ear can perceive and the pain threshold is 1:10 trillion. To depict this enormous range objectively, acoustics uses the logarithmic decibel scale. On this scale, the value “0” is assigned to the perception threshold (for a sound of 1,000 Hz) and the pain threshold at the value “130”. An increase of 10 dB corresponds to a tenfold increase in sound intensity. For the perceived volume, a difference of 10 dB corresponds to half or double the volume. However, the human ear is not equally sensitive across the entire range of frequencies. Low and high sounds are not perceived as being equally loud even at the same intensity. For measure- ments, this difference is equalized and noted accordingly. The best known such notation is the A value, marked by the index dB(A). To measure aircraft noise, the EPNdB (Effective Perceived Noise Decibel) unit is used internationally. Diversity In a corporate context, diversity refers to all characteristics that distinguish employees from one another. Diversity management offers approaches for handling human differences for the benefit of company and employees alike. DLR – Deutsches Zentrum für Luft- und Raumfahrt (German Aerospace Center) The DLR serves scientific, economic, and social purposes. It maintains 32 institutes and research centers. Its declared goal is to help – using the means of aviation and space flight – to secure and shape the future. In its work, the DLR also seeks cooperation and allocation of research tasks among European partners. www.dlr.de DNWE – Deutsches Netzwerk Wirt- schaftsethik (German Network for Business Ethics) DNWE is a nonprofit organization of which Lufthansa has been a member since January 1998. DNWE has more than 600 current members, including many from German business, politics, religion, and science. At the same time, DNWE is a national association of the European Busi- ness Ethics Network (EBEN). www.dnwe.de E econsense – Forum Nachhaltige Ent- wicklung der Deutschen Wirtschaft e.V. (Forum for Sustainable Develop- ment of German Businesses) An association of globally active corpora- tions and organizations in German industry that have integrated the guiding principle of sustainable development into their corporate strategies. Lufthansa is a founding member of this cross-industry network, which was set up in 2000. www.econsense.de
