How to best address aviation’s full climate impact froman economic policy point of view? – Main results from AviClimresearch project

The interdisciplinary research project AviClim (Including Aviation in International Protocols for Climate Protection) has explored the feasibility for including aviation’s full climate impact, i.e., both long-lived CO2 and short-lived non-CO2 effects, in international protocols for climate protection and has investigated the economic impacts. Short-lived non-CO2 effects of aviation are NOx emissions, H2O emissions or contrail cirrus, for instance. Four geopolitical scenarios have been designed which differ concerning the level of international support for climate protecting measures. These scenarios have been combined alternatively with an emissions trading scheme on CO2 and non-CO2 species, a climate tax and a NOx emission charge combined with CO2 trading and operational measures (such as lower flight altitudes). Modelling results indicate that a global emissions trading scheme for both CO2 and non-CO2 emissions would be the best solution from an economic and environmental point of view. Costs and impacts on competition could be kept at a relatively moderate level and effects on employment are moderate, too. At the same time, environmental benefits are noticeable

Coordinated Delay Management at Intermodal Transport Hubs

Abstract Delays due to missed connections at an intermodal hub such as an airport or train station may cause individual and overall economic costs. Travelers experience individual stress and may incur costs due to missed business appointments or lost vacation or spare time, for example. Transportation companies may encounter higher costs due to a delay, e.g., for additional employees or overtime, including at night, as well as for rebooking, compensation payments on the basis of passenger rights regulations, or, for example, if entire journeys or flights have to be canceled due to delays. Currently, delays are hardly considered and managed in a coordinated way as expert interviews conducted by the authors revealed. Our modelling results indicate that a coordinated intermodal delay management at intermodal hubs that considers the whole travel chain on the way to the airport can lead to advantages over the current, uncoordinated management of delays
