... GSE Emissions Inventories 23 • Data needs and availability -- Of the factors and considerations given to preparing an airport GSE emissions inventory, the availability of input data and supporting information is potentially one of the most meaningful and limiting. For example, aircraft and GSE fleet data (e.g., fleet mix, utilization times, etc.)

... GSE Emissions Inventories 25 3.4.2 Making a Selection As above in Section 3.3, there are a number of factors to consider when formulating an approach to preparing an airport emissions inventory, and in Section 3.3.4 the pros and cons of each approach are identified. This section serves as a final distillation of the decision-making process to aid guidebook users in the selection process.
