Challenges
Distribute the fuel consumption by each sector
Cover emissions from other sources (e.g. fugitive emissions)
Methodology -fuel consumption by
sector
Total Fuel quantities received from the Fuel administration
Distribution of energy by sector
Known - Electricity, Fuel Refining and Transport
An ICBS Industry Survey
Mining and quarrying, Manufacturing and electricity
Estimation of the Fuel Administration
Estimation using the Input-Output Tables,
Based on monetary values
