While reviewing the Energy Sector-Fuel combustion part of a
Party’s inventory submission, you should consider the
following issues related to the use of calorific
values for fuel products:
- Has the Party used net calorific values (NCV) as requested
in the Common Reporting Format (CRF)?
- If the Party has used gross calorific values (GVC), has
it provided documentation on how to convert this data to
a NCV basis in the documentation box for Table 1.A(a) and
in its National Inventory Report (NIR)? (As a rule of thumb,
NCVs for natural gas
are 9 to10 percent lower than GCVs and NCVs are about
5 percent lower for oil and coal
products)
- Has the Party used country-specific net calorific values?
- If default net calorific values were used, are they representative
of a Party’s national circumstances?
- Has the Party addressed likely changes in calorific values
due to changes in fuel composition over time?
- Are the calorific values used by the Party for its inventory
consistent with those used for its own energy statistics
and for its reporting to the International Energy Agency
(IEA)? If
not, why?
