  1. Lufthansa German Airlines Our commitment in reducing climate impact and supporting climate research Dr. Andreas Waibel Milano COP 9 – Climate Change Kiosk Dec 09, 2003

  2. The interaction and mechanisms of our atmosphere are manifold and complex. Fact Mobility causes consumption of naturalresources and generates emissions. The human being interferes into this complex system without knowing exactly the impacts. Dilemma But nobody wants to abstain from mobility. There is a big need to explore the mechanisms of our atmosphere. Environmental impacts due to our mobility have to be minimized on one‘s best. Need our contributions ... reducing emissions ... supporting science Our climate mission ...

  3. Air traffic emissions NOx3 - 30 CO 0.7 - 2.5 SO20.4 - 0.8 UHC 0.1 - 0.7 Soot 0.01 - 0.5 CO23150* H2O 1240 emission [g] * EI = burned fueld [kg]

  4. CO2 emissions from air traffic can not be neglected – but are still a minor source 2% air traffic 4% other traffic 10% road traffic 15% burning of bio mass industry 21% 23% households power plants 25% source: DLR 1998, AEA 1998

  5. NOx abundance at flight altitudes originate from various sources NOx concentration contribution at 30-60°N and 9-11 km altitude Source: Lee et al., 1997

  6. overall development normalized to 1990 * Anthropogenic radiative forcing – future development and aviation‘s fraction 5,1% 5,0% 4,1% 3,5% 1,2 2,7* 1 1,6 1990 2000 2015 2050 source: IPCC 1999

  7. DLR‘s research aircraft Falcon behind a B737300 of Lufthansa SulfurExperiment (1996 and 1998) Lufthansa takes activ part in scientific climate research projects What influences the formation of condensation trails? Contrail Experiment (1999) A modern Airbus A340-300 (left) of Lufthansa and a Boeing 707 (right) of the German Airforce in front of DLR‘s research aircraft Falcon.

  8. Lufthansa takes active part in monitoring our atmosphere Since more than 9 years continuous measurements on each flight onboard of 3 A340-300 long haul aircrafts of atmospheric O3 and H2O Significance: Cloud Formation, Climate Research, Chemistry (OH)

  9. MOZAIC Operation 2.500 Flights per year (5000 vertical profiles) 1994–2002: 19.000 flights with O3/H2O instrumentation 130.000 flight hours of O3 and H2O data 2001-2002: 500 flights with additional CO 500 flights with additional NOy 200 flights with additional CO/NOy 5 Long-range Aircraft (A340-300) operated by: Lufthansa (2+1), Air France, Austrian Airlines, Sabena

  10. A further long term project to investigate our atmosphere • 1,6 t • as of May 2004 • planed operating time: 10 years • one of the new A340-600 delivered to LH • O3, CO, CO2, H2O, NOX, NOY, Aerosole, organic compounds CARIBIC Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container An European atmospheric research project operated by Lufthansa

  11. Specific fuel consumption has been continuously reduced ... 4.5l/100pkm average specific fuel consumption of the whole passenger fleet in 2002 27 % reduction since 1991 ... due to continuous fleet modernisation

  12. Lufthansa has decoupled transport performance and environmental impact ... + 125 % PKT + 75 % NOx + 57 % Fuel - 4 % CO - 51 % UHC ... due to continuous fleet modernisation

  13.  68 % In other words... 150% More than halve of the growth in the past 12 years could be performed in an enrionmental neutral manner + 125 % PKT 100% delta (%) + 57 % Fuel 50% 0% 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 -50%
