Research background Aviation causes nitrogen oxide (NO X ) and hydrocarbon (HC) emissions in the vicinity of airports NO X and HC are main contributors to combustion-related local air pollution und precursors of ground level ozone Some German airports have introduced a standardized emission charge targeting these emissions What are the economical and ecological effects after the charge has been in operation for > 3 years?

Design of the emission charge at German airports EV A/C = E * EEV (Engine Emission Value) where EV A/C = Emission Value Aircraft E = Number of engines EEV = Engine Emission value EEV = a * NOx Engine/LTO cycle where: a = Multiplicator for aircraft/engines with hydrocarbon (HC) emissions exceeding 19,6 g/kN (does not apply to most relevant engines; here: a=1) Charge = 3 € * EV A/C = 3 € per kg of NOx equivalent during the standardised LTO cycle Sweden: 5.5 € Switzerland: 1-3 € UK: 1.6 € Page 7 Maertens – GARS – 9-10 MAR 2010

Design of the emission charge at German airports Certified values matter, not actual emissions (ICAO Engine Emissions Data Bank as reference) Operators have to proof actual engine types (UID number) with noise certificates or similar aircraft-specific documentations REG-EV database (monitored by the DLR), containing 19,600 aircraft Source: DLR, Fraport Page 9 Maertens – GARS – 9-10 MAR 2010

Design of the emission charge at German airports Revenue-neutrality Total airport revenues (from weight- and noise-based landing fees + the new NOx charge) must not increase Ex-ante estimation of the volume of NOx-related revenues Reduction of the weight-based landing fees – over all carriers – by this amount Some airlines (with high NOx emissions) pay more than before, others pay less, in total all airlines pay the same as before Source: Scheelhaase et al.

Impacts of the charge – a first assessment Questions Overall objective of the charge: Reduction of NOx emissions! But do we have a local air quality problem at (German) airports? Does the charge give an incentive to purchase low-NOx aircraft? Does the charge influence operational decisions by the airlines? Methodology Quantitative assessments and calculations wherever possible Interviews with stakeholders Page 12 Maertens – GARS – 9-10 MAR 2010

Impacts of the charge – a first assessment Local air quality at German airports Local air quality is monitored at all larger airports Frankfurt Airport (annual mean values) Nitric oxide NO = 36 μ g/m 3 (reference = 200 μ g / m 3 ) Nitrogen dioxide NO 2 = 31/39/45 μ g/m 3 (3 measuring points on the airport premises; limit = 40 μ g/m 3) Higher concentrations (except for Sulfur dioxide SO 2 ) at other places in the Frankfurt region Involuntary experiment inm April 2010 („ash cloud period“) No significant reduction of pollutant concentration Car traffic and other factors seem to have much more influence than air transport No local air quality problem at the German airports! Is the charge nevertheless justified? Page 13 Maertens – GARS – 9-10 MAR 2010

Impacts of the charge – a first assessment Does the charge give an incentive to purchase low-NOx aircraft? Does the charge significantly punish operators of high-NOx aircraft? What are the alternatives? Total cost perspective necessary! Page 14 Maertens – GARS – 9-10 MAR 2010

Impacts of the charge – a first assessment Additional outcome of the stakeholder interviews Airlines: no additional competitive disadvantage for most airlines + (except some carriers operating relatively old cargo aircraft) Hardly any impact on flight operations and aircraft scheduling: other factors such as aircraft capacity and demand, overall - airport costs, planning of scheduled maintenance visits are much more dominant and hardly leave any room for carriers to react Airports: Signaling, long-term perspective Working policy measure in place + Low transaction costs Good publicity?
