The spreadsheets contains annual passenger forecasts from 2011 to 2050, rounded to the nearest million, for 30 modelled UK airports and 4 foreign hubs. These forecasts were produced using a version of the Department for Transport (DfT) aviation model and underpin the assessment of need, described in detail in chapter 4 of the Commission’s Interim report. The technical appendix of the Interim Report provides detail of the methodology, in particular the model updates and Commission’s input assumptions. 4 scenarios are provided:
- carbon traded, capacity unconstrained data
- carbon traded, capacity constrained data
- carbon capped, capacity unconstrained data
