AIRCRAFT EMISSIONS: A COMPARISON OF METHODOLOGIES BASED ON DIFFERNT DATA AVAILABILITY

摘要

The impact of air traffic on the global atmosphere is characterised by a high degree of uncertainty, kconcerning both the physico-chemical phenomena involved and the extent of the forcing due to anthropogenic emissions. The different effects of these emissions (e.g. on climate change, strategospheric ozone depletion, acidification, tropospheric ozone formation) are dealt with by different international bodied and conventions (e.g. IPCC, EMEP...) which are trying to define a standard methodology allowing countries to evaluate their contributions to bloal aircraft emissions and to report these figures in a standardised way. The paper compares different methodologies proposed by the joint EMEP/CORINAIR `Atmospheric Emission Inventory Guidebook' for estimating aircraft emissions.
