5 Non-energy-related physical and chemical processes in production activities leading to transformation of raw materials and emissions of greenhouse gas (GHG) (e.g. decomposition reactions). Non-energy uses (NEU) of feedstock in process reactions or stage processes that do not only release heat but also act predominantly as reducing agent (e.g. metallurgical coke in the smelting of ores in metal production). The energy/heat required for initiating and/or sustaining the chemical reaction kinetically and thermodynamically is accounted for under energy sector. Definitions (Revised 1996 IPCC Guidelines) 5 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

6 Feedstock delivered to petrochemical plants and used for manufacture of other products and not for energy purposes (e.g. use of natural gas or other fossils in the manufacture of ammonia). Production-related emissions are NOT classified under the industrial processes sector but under energy sector are GHGs released from fuel combustion of feedstock in production activities as sources of energy forms of energy (i.e. heat, process steam or electricity generation).

42 The problems encountered in using IPCC 1996GL and available GPG options are summarized in this section. The impact of the problem on inventory preparation and practical approaches recommended, and/or the GPG Options, are provided in the notes. 42 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE) Problems Encountered in Using IPCC 1996GL and GPG 2000, and Recommendations

43 Difficulty in disaggregation of country-relevant sources into IPCC categories, particularly sub-source categories not listed in the Revised 1996 IPCC Guidelines. The “mapping technique” is a practical approach recommended for ease of identification and disaggregation of country sources into IPCC source categories. The Handbook provides IPCC disaggregation and corresponding probable national emission sources. Potential Problems in Preparing IP Sector Inventory 43 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

44 The Handbook presents a sample of mapping national source categories and IPCC source classification. The table helps to easily identify corresponding IPCC source categories for each probable national emission source, thus facilitating correct disaggregation. 44 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE) Mapping National Industry Classification with IPCC Source Categories

45 Direct reporting of emissions without AD and/or EF to national institutions responsible for data collection because of confidential business information (CBI). Impact on inventory preparation Reduces transparency and comparability Recommended approach/GPG 2000 Option GPG recommends plant-level verification and assessment of the measurement standards and QA/QC plan of the industry. Potential Problems in Preparing IP Sector Inventory Activity Data Collection and CBI 45 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

46 The reporting of industrial process emissions from non-energy use (NEU) of feedstock produced in combination with fuel combustion under energy sector due to the difficulty in differentiation and possible double counting of CO 2. Direct plant-level measurement and reporting of industrial process emissions of CO 2 from chemical processes or stage processes in combination with fuel combustion emissions from energy uses of feedstock (e.g. CO 2 emissions from CaCO 3 decomposition and metallurgical coke oxidation in Solvay process). Impact on inventory preparation Underestimation of the contribution of IP sector to national emissions (e.g. the use of natural gas in ammonia production, and coke as reducing agent in iron and steel production). Recommended approach/GPG 2000 Option GPG2000 recommends stoichiometric estimation of the NEU and subtraction from the energy statistics to avoid double counting. Potential Problems in Preparing IP Sector Inventory Emissions Estimation Methods and Reporting 46 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

47 Where technology-specific or plant-level data are not available, EF(default) are based on stoichiometric ratios of process reactions. Potential Problems in Preparing IP Sector Inventory Inappropriateness of Stoichiometric Ratios as EFs 47 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

48 Lack of development of plant-level EFs, which leads to the estimation of EFs based on top-down ratios calculated as EF = Emissions/Aggregate AD. Impact on inventory preparation EFs estimated based on the aggregate AD is basically a IPCC 1996GL IPCC Tier 1 approach. It lacks transparency and comparability and the method is not considered good practice. Recommended approach/GPG 2000 Option GPG2000 provides good practice based on “decision tree” in applying IPCC 1996GL to various national circumstances. Potential Problems in Preparing IP Sector Inventory Lack of Emission Factors 48 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

50 Other Specific Problems Encountered in the Use of IPCC 1996GL Suggested Approaches/Options 50 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

51 Inappropriate use and/or limited use of notation keys (NO, NE, NA, IE, NE) in UNFCCC reporting Table 1 and Table 2. This results in lack of transparency and does not address completeness of the inventory coverage. Potential problems in preparing IP Sector Inventory Notation Keys in UNFCCC Reporting Tables 1 and 2 51 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

52 NO (not occurring) for activities or processes that do not occur for a particular gas or source/sink category within a country. NE (not estimated) for existing emissions and removals which have not been estimated. NA (not applicable) for activities in a given source/sink category which do not result in emissions or removals of a specific gas. IE (included elsewhere) for emissions and removals estimated but included elsewhere in the inventory (Parties should indicate where the emissions or removals have been included). C (confidential) for emissions and removals which could lead to the disclosure of confidential information. Completeness and Transparency in Reporting – Use of Notation Keys 52 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

53 Production data on large point sources may be available in various national institutions in data sets that are not easily converted to greenhouse gas inventory data. Where available, mandatory or voluntary plant-level data are reported as total emissions without relevant AD and EFs. Potential problems in preparing IP Sector Inventory Activity Data Collection and Reporting 53 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

54 Mandatory industry reports (e.g. annual environmental reports) provide only emissions estimates without AD and/or EF. Lack of IPCC default EFs due to differences in IPCC source and sub-source categories and disaggregation of country-relevant sources. Potential Problems in Preparing IP Sector Inventory Lack of Emission Factors 54 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

55 National institutions and industry associations collect and present data in formats not appropriate for GHG estimation (because they are normally aggregated in data sets relevant for the purposes for which they were collected). Limited awareness among industry/industry associations about opportunities under the Convention and therefore lack of motivation to develop capacity for reporting GHG inventories. Potential Problems in Preparing IP Sector Inventory Institutional Arrangements 55 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

56 Lack of institutional arrangements and clarity over roles and responsibilities of experts carrying out the technical studies. Lack of legal and institutional authority to demand data from industry to carry out the inventories (reporting is basically voluntary). Potential Problems in Preparing IP Sector Inventory Institutional Arrangements (cont.) 56 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

57 Non-involvement of universities and/or research centres in climate change efforts that could develop into a more sustainable inventory system. Lack of mainstreaming of climate change data collection by national statistical services and industry associations. Lack of QA/QC and uncertainty analysis by data collection institutions. Potential Problems in Preparing IP Sector Inventory Institutional Arrangements (cont.) 57 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

58 Establish a national working group of relevant stakeholders for plant-level verification and peer review of the inventory report. Organize a capacity-building seminar for all institutions and relevant GHG- contributing industries to disseminate the IP inventory data sets, to inform about the need for QA/QC and plant-specific good practice in developing and reporting AD and EFs in greenhouse gas inventory data sets. Institutional Arrangement Problems How a country could benefit from capacity-building 58 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

59 Adapt the Revised 1996 IPCC Guidelines and GPG 2000 and develop country- specific workbooks documenting methods, AD, EFs to increase transparency and preserve institutional memory. In a capacity-building workshop, disseminate information about the opportunities for emission reduction under the Convention and the financing mechanisms under the Protocol to encourage industry participation. Institutional Arrangement Problems Recommended capacity-building (cont.) 59 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

60 Review and Assessment of Activity Data and Emission Factors Data Status and Options 60 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

61 GPG 2000 Approach and Steps Inventory Quality Improvement and Uncertainty Reduction QA/QC Approach GPG 2000 presents a systematic approach to default uncertainty estimations for various national circumstances based on decision trees. For instance, in the case of cement production, a detailed approach is provided in Table 3.2, which is based on Decision Tree Figure 3.1. 61 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)
