5.3. Comparison of CO₂ emissions from fuel combustion (Table 1.A(c) – sheet 1)

Table 1.A(c)

This table provides a comparison between a Party’s Reference Approach and Sectoral Approach calculations for aggregate apparent energy consumption of major fuel types (i.e., solid, liquid, and gaseous), and other fuels and CO₂ emissions. This comparison is to assist in verifying the sectoral data and identify potential inconsistencies in the calculations.

For the purposes of comparing apparent energy consumption from the Reference approach with energy consumption from the Sectoral approach, a column is included in this table with the energy content corresponding to the fuel quantities used as feedstocks and/or for non-energy purposes subtracted from apparent consumption.  Because most of the carbon in feedstocks and non-energy use fuels will not be emitted (or the emissions will be accounted for in the Industrial Processes sector), subtracting it from apparent consumption gives a more accurate basis for comparison.

This table also includes a documentation box stating that the Parties should explain differences between CO₂ emissions calculated using the Reference Approach and the Sectoral Approach. Specifically, Parties should provide an explanation when the difference exceeds 2 percent and refer to the chapter of their National Inventory Report (NIR) where this difference is explained in more detail.

5.4. Sectoral background data for energy (Table 1.A(d) – sheet 1) – Feedstock and non-energy use of fuels

Table 1.A(d)

This table provides information on fuel quantities (TJ) that are utilized as feedstocks (i.e., fuels used as raw materials for production of materials such as plastics or fertilizers) or for non-energy uses (e.g., bitumen and lubricants). The table also includes a column with implied factors for carbon emitted (t C/TJ) for each fuel type, as well as estimates of the quantity of carbon stored (Gg C).

Additional tables show the amount of CO₂ not emitted because it was stored in products, and the CO₂ emissions associated with feedstock and non-energy uses.  Each table also has a column to indicate where this carbon was allocated in the inventory.
