The AMEE category /transport/byFuel/ipcc/ship contains data and a methodology sourced from the IPCC Guidelines for National Greenhouse Gas Inventories for calculating emissions associated with fuel used in water-borne transport contexts.

Using this methodology

Choosing a specific activity type

To use this category, select the fuel type and use context using the fuel and useContext drill options. At present, only a single item is available representing a 'diesel' powered (the fuel drill option) 'ocean-going ship' (useContext).

Activity data required

Next, specify the quantity of fuel consumed. This can be specified either as a volume, using the volumeConsumed profile item value, or directly as a quantity of energy, using the energyConsumed profile item value.

Calculation and result

The returned quantities for this methodology represent CO2, CH4 and N2O emissions associated with the specified quantity of fuel. The following discrete amounts are returned:

  • CO2: CO2 emissions
  • CH4: CH4 (methane) emissions
  • N2O: N2O (nitrous oxide) emissions
  • CO2e: CO2e emissions (all three gases, converted using these global warming potential)

The individual quantities for CH4 and N2O represent absolute quantities rather than CO2e quantities.
