2. Aviation - navigation

3. België – La Belgique – Belgien
UNFCCC
Regional authorities
Cooperation agreement and federal authorities
Main country specific problem:
GHG emission inventory: regional issue
In spite of consultation: differences in methodology
Rechearch Institutes
IEA/Eurostat

4. Aviation Flanders Wallonia Activity data From different airports
Emission factors
CO2: IPCC
CH4, N2O: EMEP/Corinair
Bunker
Gasoline = domestic
Kerosene = international
Military: same segmentation
Details from one airport, estimate for the other
Military = domestic, unless stated otherwise

5. Navigation Flanders Wallonia Brussels Activity data
From different administrative bodies
Regional ministry
Port of Brussels
Fuel consumption
Average fuel consumption
Emission factor
CO2: IPCC
CH4, N2O: EMEP/Corinair
Bunker
Based on Belgian Petrol Balance (supply survey)
Fishery  agriculture
(not relevant)

6. Problems Different responsible authorities:
difference in data and methodology
Data collection: on voluntary basis
Not all airports provide all needed information
Data collection from different sources
Especially for inland navigation
Very difficult to distinguish between local / international

7. EU EU level data EU-domestic / international
Usefulness depends on allocation method and level of detail
Might be useful for verification purposes
Definitions of bunker fuel: harmonisation desirable
EU-domestic / international
Not feasible for Belgium
Aviation: Eurocontrol/-stat data can be very useful
Which country can ?

8. Future plans Flanders:
Model for estimation of emission of inland navigation and rail
Based on fuel consumption survey among bargees
Project Mopsea: monitoring pollution of sea-going vessels
