Major environmental impacts Air pollution (Emissions) – greenhouse effect Ground water contamination Soil contamination Noise

Pollutants considered to be the most dangerous - so called Greenhouse gases Carbon dioxide (CO 2 ) Nitrogen oxides (NO x ) Water vapor (H 2 O) Methane (CH 4 ) Carbon monoxide (CO) and Microscopic particles and related water condensation

Do you know that? (the amount of CO 2 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 emissions today

Emissions - future By 2050 – aviation produces % of all emissions of CO 2 ACARE (Advisory Council for Aviation Research) – reduction of CO 2 emissions beween 2001 and 2020 – reduction of NO X 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
