How are greenhouse gas emissions measured?
Direct measurement not being feasible, greenhouse gas emissions are estimated based on air traffic movement data and modelling of the related fuel consumption and pollutant emissions. The ENV Domain within the Directorate of ATM Strategies, and the PRISME Data Warehouse team within the Directorate of ATM Programmes, are currently working on the PAGODA project to develop a new facility to estimate the fuel burnt and GHG emitted from all flights within the CFMU area. The PAGODA service prototype is being used to provide the Commission with the key datasets that are essential to carrying out the policy scenarios specified within the study. EUROCONTROL has already provided estimates of fuel burnt and greenhouse gases emitted for the years 2002, 2003 and 2004 and is currently working on supplying complex sets of data to support the various “emissions allocation options” that the UNFCCC has studied and the EC is considering for the ETS. PAGODA implements an aircraft fuel burn and emissions m
