Aviation Turbo fuel sales reported in the RESD
1st Generation MethodologyFuel Sales Based
Early Inventories used fuel sales reported in National Energy Balance (RESD) to split International from Domestic
Sales to Domestic Airlines were allocated to Civil (Domestic) Aviation, Sales to Foreign considered International (Bunker) travel.
1st Generation Methodology last used for 2004 Submission (1990-2002 Inventory)

Turbo Fuel MethodologyTonne kilometres traveled by Canadian Carriers
Tonne Kilometres are reported by Statistics Canada for Canadian Carriers by sector (Dom/Int/Other Int) and include both passenger and freight activity
Method developed by Transport Canada for Revenue Canada to estimate the tax revenue expected as a result of fuel sold to Canadian Carriers for domestic flights
Assumption is that 50% of international tonne kilometres flown by Canadian Airlines uses domestically purchased fuel

Validation of Results
Comparing our results with SAGE to verify our initial assumption on the percentage of international Tonne-Kilometres flown by Canadian Carriers on domestically purchased fuel (Initial assumption was 50%)
SAGE (System for Assessing Aviation's Global Emissions) was developed by the FAA to predict aircraft fuel burn and emissions for civil aviation globally.
Adjusting from 50% to 69% minimized difference between initial results and SAGE output.
