ANNEX 1
MAPPING TABLES

This annex provides a road map for relating sections, equations, tables, figures and boxes in the 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. Type of Refinement: U – Update, NG – New Guidance, NR – No Refinement, R – Removed.
CHAPTER 1 INTRODUCTION TO NATIONAL GHG INVENTORIES
Refinements undertaken for Chapter 1 involve primarily guidance on establishing GHG inventory arrangements that can support the development, improvement and maintenance of national GHG inventories. The Section 1.1 has been updated by elaboration of concept of anthropogenic emissions and removals related to additional and voluntary estimation and reporting of emissions and removals from natural disturbances in Chapter 2 of Volume 4. A sub-section on the treatment of CO 2 , CH 4 and N 2 O emissions from combustion of biomass or biomass-based products has also been added. The chapter introduces the concept of institutional arrangements and some examples on the functional roles of organisations in the national inventory compilation process. The chapter describes the use of different data management systems needed for calculating estimates and for aggregating and reporting GHG inventory data.

This chapter includes a series of updates that include improvements in the explanation of the methodology for indirect N 2 O emissions from the atmospheric deposition of nitrogen in NO x and NH 3 , detailed methodological guidance on treatment of CO 2 inputs to the atmosphere from emissions of carbon-containing compounds, an update on the background science on precursors and indirect emissions. The chapter also incorporates updated guidance on non-biogenic sources of CO 2 from the atmospheric oxidation of CH 4 , CO, and NMVOCs, examples of NMVOCs from the different source categories as well as data on carbon content of various materials (percent carbon by mass, PC) and percent of total solvent NMVOC emissions (by mass, PU).
