Annex 1: Worksheets
1.1 INTRODUCTION
This Annex presents worksheets to enable inventory compilers to readily implement the Tier 1 methods. Volume 1, Chapter 8 gives guidance on how to report the resulting emission estimates.
Table 1 explains the main considerations concerning fuel consumption to be taken into account with respect to column A of the fuel combustion activities worksheets.
Worksheets for fuel combustion activities also cater for CO2 capture from the subcategories 1A 1 and 1A 2. Emissions of CO2 from biomass fuels are estimated and reported in the AFOLU sector as part of the AFOLU methodology. In the reporting tables, emissions from combustion of biofuels are reported as information items but not included in the sectoral or national totals to avoid double counting. Worksheets for fugitive emissions are of two types:
(1) Emissions arising from mining, processing, storage and transportation of coal. This includes the
new method of determining CH4 emissions from abandoned coal mines. (2) Emissions from oil and natural gas systems.
Reference Approach worksheets are also included though its main purpose in the 2006 IPCC Guidelines is to serve as an independent verification cross-check of the bottom-up approach methods described in Tiers 1, 2 and 3.
