Fuel Manager• Contains main parameters on fuels, i.e. fuel type, calorific value, carbon
content- needed to estimate GHG emissions from combustion• Allows input of user-defined fuels and their parameters• Information from fuel manager transfers to all corresponding worksheets• In any relevant worksheets to estimate GHG emissions from source-categories
where fuels are used, if IPCC default fuels are selected, the parameters arefilled automatically in the worksheet

Fuel Manager

Stationary Combustion
2 worksheets are provided to estimate emissions
A. Fuel Consumption Data - subdivision, fuel, consumption amount, units,
conversion factor• consumption units can be selected from the defaults (Gg, TJ) - in this caseconversion factor being filled automatically from Fuel Manager• or entered directly whatever unit is provided – and conversion factor thus beentered manually
B. Fuel Combustion Emissions – technology type and penetration rate bysubdivision/fuel, EFs for each technology/fuel• click “+” at left to expand subdivision and fill in data
• Technology type can be left “unspecified” (e.g. Tier 1) or compiled withseveral ones (if available)• All technology penetration rates should sum up to 100% for each fuel insubdivisionStationary Combustion

Road Transportation
Tier 1, 2, 3 are implemented via 4 worksheets• Fuel Consumption Data: the amount of fuel consumed for each [fueltype/vehicle type/emission control technology]• Fuel Combustion Emissions: EFs and calculation of emissions for each [fueltype/vehicle type/emission control technology]• CH4 and N2O Emissions – Tier 3: used for Tier 3 estimations of methane andnitrous oxide considering the fuel type, vehicle type, emission control
technology, operating conditions, distance travelled and emissions on cold startof the vehicle• Fuel Consumption – Validation: estimation of fuel use from the distancetravelled data based on the types of fuel/vehicle/roadRoad Transportation

Road Transportation

Road Transportation

Railways
Tier 1, 2, 3 are implemented via 3 worksheets• Fuel Consumption Data: the amount of fuel consumed for each[fuel/locomotive type], either entered directly, or calculated via Equation 3.4.5
based on the number of locomotives, specific fuel consumption and number ofdays in operation• Fuel Combustion Emissions: EFs and pollutant weighting factors for each[fuel/locomotive type], calculation of emissions• CH4 and N2O emissions – Tier 3: used for Tier 3 estimations of methane andnitrous oxide considering the fuel, locomotive type, number of locomotives,
annual hours of use, rated power of locomotive and load factor of locomotiveRailways

Off-road transportation
Tier 1, 2, 3 are implemented via 3 worksheets• Fuel Consumption Data: the amount of fuel consumed for each[fuel/vehicle/equipment type]• Fuel Combustion Emissions: EFs for each [fuel/vehicle/equipment type],
calculation of emissions• CH4 and N2O emissions – Tier 3: used for Tier 3 estimations of methaneand nitrous oxide considering the fuel, vehicle type, number of vehicles,
annual hours of use, rated power of vehicle and load factor of vehicleOff-road transportation

Fugitive – Solid – Abandoned mines
Tier 1, 2, 3 are implemented via 2 worksheets• CH4 Emissions From Abandoned Coal Mines: counts for Tier 1 emissions
based on time from closure, number of mines and fraction of gassy mines• CH4 Emissions From Abandoned Coal Mines – Tier 2&3: counts for Tier 2and 3 methane emissions

Fugitive – Oil – Venting

Tier 1 and 2 are implemented via 3 worksheets• Activity Data: amount of oil production for each [subdivision/industrysegment/subcategory], selection of calculation method Tier 1 or 2. This
information transfers to “Flaring” category automatically and vice-versa• Emissions – Tier 1: CO2 and CH4 emissions for Tier 1 for each
[subdivision/industry segment/subcategory]• Emissions – Tier 2: CO2 and CH4 emissions for Tier 2 for each
[subdivision/industry segment/subcategory] based on the molecular weight andfraction of associated gas

Fugitive – Oil – Venting

Fugitive – Oil – FlaringTier 1 and 2 are implemented via 5 worksheets• Activity Data: amount of oil production for each [subdivision/industrysegment/subcategory], selection of calculation method Tier 1 or 2. This
information transfers to “Venting” category automatically and vice-versa• Emissions – Tier 1: CO2, CH4 and N2O emissions for Tier 1 for each
[subdivision/industry segment/subcategory]• CH4 Emissions – Tier 2: CH4 emissions for Tier 2 for each [subdivision/industrysegment/subcategory] based on the flaring destruction efficiency, molecularweight and fraction of associated gas• CO2 Emissions – Tier 2: CO2 emissions for Tier 2 for each
[subdivision/industry segment/subcategory] based on the molecular weight,
fraction of associated gas and fraction of non-CO2 carbon of waste gas• N2O Emissions – Tier 2: N2O emissions for Tier 2 for each
[subdivision/industry segment/subcategory] based on the nitrous oxide EF
