allocatiemethoden

Calculation of aviation emissions for several
allocation methods

Abstract
Dit rapport gaat in op de toedeling van emissies door
internationale luchtvaart aan landen. Momenteel wordt een klein deel van
deze emissies aan landen toegerekend, voor koolstofdioxide betreft dit
bijvoorbeeld alleen de emissies door binnenlandse luchtvaart. Omdat
internationale luchtvaart grensoverschrijdend is, zijn de emissies die
hierdoor veroorzaakt worden, niet eenvoudig aan een land toe te rekenen.
Anno 2002 is in diverse internationale kaders (IPCC, V.N.) gediscussieerd
over de vraag of de emissies wel toebedeeld moeten worden aan landen.
Wanneer afspraken gemaakt worden over de allocatie van emissies door de
internationale luchtvaart, zal waarschijnlijk de bereidheid om deze emissies
te verminderen toenemen. Er zijn reeds diverse allocatiemethoden
voorgesteld. Het onderhavige onderzoek richt zich op de vraag wat de
implicaties van de diverse voorgestelde allocatiemethoden zijn voor de aan
Nederland toe te rekenen emissies. Om de consequenties te kunnen
inschatten, is het model MOBLEM ontwikkeld. Het model berekent dat, door de
toedeling van de internationale luchtvaartemissies, onder andere de omvang
van de jaarlijkse Nederlandse rapportage van CO2-emissies door de luchtvaart
met maximaal een factor 27 stijgt. MOBLEM blijkt goed toepasbaar voor de
berekening van de emissies voor de allocatiemethoden, maar dat met name de
resultaten voor HC- en CO-emissies gevoelig zijn voor veronderstellingen
over onzekere factoren. Onzekerheden betreffen de gebruikte emissiefactoren
en de representativiteit van de gebruikte vloot.
This study deals with the allocation of international aviation emissions to countries. Currently, only a small proportion of the emissions from aviation is allocated to countries; for example only the carbon dioxide emissions from domestic flights are allocated. Because international aviation is cross-bordered, it is not easy to allocate emissions to a country. A discussion about whether to change this is currently being carried on in the international framework (IPCC, UN). Once an agreement on the allocation of the emissions from international aviation is reached, the willingness of countries to reduce these emissions will probably increase. Several allocation methods have already been proposed. The study documented here is an attempt to answer the questions on what the consequences of the proposed allocation methods for the emissions allocated to the Netherlands are. The importance of the chosen allocation method will even increase in the future, considering the anticipated strong growth in aviation. To be able to calculate the consequences, the model MOBLEM is developed. According to the calculations of the model, the CO2 emissions from aviation which the Netherlands report each year, rises with a factor of 27 increase. MOBLEM was found well applicable to the calculation of the emissions for several allocation methods, but especially the results for HC- and CO-emissions were sensitive to uncertainties. Uncertainties are the used emission factors and the representativeness of the used aircraft fleet.
