46. 2.46 46 SECTION C REVIEW OF PROBLEMS ENCOUNTERED IN USING Re96GL and GPG 2000 OPTIONS

47. 2.47 47 Potential problems in preparing IP Sector Inventory Difficulty in disaggregation of Country relevant Sources into IPCC categories particularly sub-source categories not listed in Re96GL.

48. 2.48 48 mapping national industry classification with IPCC Source categories

49. 2.49 49 Potential problems in preparing IP Sector Inventory Activity Data (AD) Collection and CBI Direct reporting of emissions without AD and/or EF to national institutions responsible for data collection because of Confidential Business Information (CBI),

50. 2.50 50 Potential problems in preparing IP Sector Inventory Emissions Estimation methods and Reporting 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 CO2.

51. 2.51 51 Potential problems in preparing IP Sector Inventory Emissions Estimation methods and Reporting Direct plant level measurement and reporting of industrial process emissions of CO2 from chemical processes or stage processes in combination with fuel combustion emissions from energy uses of feedstock (e.g. CO2 emissions from CaCO3 decomposition and metallurgical coke oxidation in Solvay process).

52. 2.52 52 Potential problems in preparing IP Sector Inventory Inappropriateness of Stoichiometric ratios as EFs Where technology-specific or plant-level data are not available, EF(D) are based on stoichiometric ratios of process reactions..

53. 2.53 53 Potential problems in preparing IP Sector Inventory Lack of Emission Factors (2) 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).

55. 2.55 55 Other specific problems encountered in the use of Re96GL SUGGESTED APPROACHES/OPTIONS

56. 2.56 56 Potential problems in preparing IP Sector Inventory - Use of Notation Keys in Reporting Tables 1& 2 Inappropriate use and/or limited use of notation keys ( “ NO ”, “ NE ”, “ NA ”, “ IE ”, “ NE ” ) in UNFCCC reporting Table 1 and Table 2.

57. 2.57 57 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,. Completeness and Transparency in Reporting - Use of Notation Keys

58. 2.58 58 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

59. 2.59 59 Potential problems in preparing IP Sector Inventory Activity Data (AD) Collection and Reporting Production data on large point sources may be available in various national institutions in data sets that are not easily converted to GGI data Where available, mandatory or voluntary plant-level data are reported as total emissions without relevant AD and EF

60. 2.60 60 Potential problems in preparing IP Sector Inventory Lack of Emission Factors (1) Mandatory industry reports (e.g. annual environmental reports) provide only emissions estimates without AD and/or EF. Lack of IPCC D-EFs due to differences in IPCC source and sub-source categories and disaggregation of country-relevant sources,

61. 2.61 61 Potential problems in preparing IP Sector Inventory Institutional Arrangements National institutions and industry association 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 are collected. Limited awareness among industry/industry associations of opportunities under the Convention and therefore not motivated to develop capacity for reporting GHG inventories.

62. 2.62 62 Potential problems in preparing IP Sector Inventory Institutional Arrangement Lack of institutional arrangement 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)

63. 2.63 63 Potential problems in preparing IP Sector Inventory Institutional Arrangement Non-involvement of universities and/or research centres on CC issues that can evolve a more sustainable inventory system. Lack of mainstreaming CC data collection by national statistical services and industry associations in data collection. Lack of QA/QC and uncertainty analysis by data collection institutions

64. 2.64 64 Intuitional Arrangement Problems Recommended capacity building Institute a national working group of relevant stakeholders for plant level verification and peer review of the inventory report Organise a capacity building seminar for all institutions and relevant GHG contributing industries to disseminate the IP inventory data sets, the need of QA/QC and plant specific good practice for development and reporting AD and EFs in GGI data sets

65. 2.65 65 Intuitional Arrangement Problems Recommended capacity building Adapt Re96GL and GPG2000 and develop country specific workbooks documenting methods, Ads, EFs to increase transparency and preserve institutional memory Disseminate the opportunities of emissions reduction under the Convention and the Financing Mechanisms under the Protocol in the capacity building workshop to motivate industry participation
