• List of major impacts• Aviation‘s share in overall pollution• Future of green aviation• Questions

Major environmental impacts

• Air pollution (Emissions) – greenhouse effect• Ground water contamination• Soil contamination

• Noise

Pollutants

considered to be the most dangerous - so calledGreenhouse gases

• Carbon dioxide (CO2)

• Nitrogen oxides (NOx)

• Water vapor (H2O)

• Methane (CH4)• Carbon monoxide (CO)and• Microscopic particles and related water condensation

Do you know that?(the amount of CO2 produced by different means of TPT per passenger and mile looks like this)

• No emission regulation so far• Growth of air transport• Kerosene contains less sulphur

compounds (Air-companies doubled its effectiveness of fuel consumption since 1990)

Aviation‘s share in emissionstoday

Emissions - future

• By 2050 – aviation produces 5 - 14% of all emissions of CO2

• ACARE (Advisory Council for Aviation Research)

– reduction of CO2 emissions beween 2001 and 2020 – reduction of NOX by 80% by 2020

• Emission allowances (according to Kyoto protocol)

– expected ratio 85% for free according performance, 15% redistributed through auction

Noise (and its reduction)

Noise and vibration -noise protection zone of an airport.

– Passive reduction• Influence of terrain• Influence of vegetation (trees)

– Active reduction• Design of sources• Engine position• Higher angle of climb• RWY in use (night restriction)• Noise reduction during approach• Air route design• Airframe ans engine design
