Pillar 2: Improved The largest climate protection project in European aviation is to establish a stan- dardized airspace above Europe. This Single European Sky (SES) would help airlines to emit 10 percent less CO2 and save about 5 billion euros in fuel costs every year. Today, however, about 60 air traf c control centers are responsible for air safety in 27 different national systems with more than 650 sectors, a system that does not always allow aircraft to follow an optimum route to their destinations. The goal of SES is to remove this kind of patchwork and to steer air traf c ows substantially more ef ciently than is cur- rently the case. An important milestone on the path toward the Single European Sky is the standardization and modernization of the European aviation infrastructure. For this purpose, the European Commission set up the SESAR (Single European Sky ATM Research) program. The goal of this project is to develop, test and implement Europe-wide new technologies, procedures and standards that contribute to harmo- nizing and optimizing the European air traf c management. The Lufthansa Group’s airlines and Lufthansa Systems are actively involved with their respective expertise in a number of SESAR research and demonstration projects as well as standardization initiatives. The synchronization of SESAR with its American counterpart “NextGen” as the basis for global interoperability of air traf c control systems has a high priority in this context. The rst modernization package was inte- grated by the European Commission in the Pilot Common Project (PCP). The implementation of these technologies in daily operations is jointly coordinated by the members of the industry consortium “SESAR Deployment Manager”. Since the start of the introduction phase in 2014, the The implementation of the Single European Sky is the largest climate protection project of European aviation. More direct routings without unnecessary detours would reduce the CO2 emissions of European airlines by 10 percent a year. 48 // Climate and Environmental Responsibility
