2D3 2014 The methodology described in the IIR for solvent and other product use is found to be not transparent. Provide detail on all 37 subcategories including activity data and emission factors. § 18 96 97 98 (CLRTAP 2014) Yes The transparency for the solvents used and products used sector in the IIR was much improved in the submission 2016.
2010 Inaccuracies were found in the use of notation keys and it is recommended to justify the use of notation keys in the IIR for each particular sector. § 38 (CLRTAP 2010);§ 19 (CLRTAP 2014) Yes Information tables for NE & IE were added to the completeness chapter of the current IIR.
2014 Provide more detailed to explain emission trends e.g. annual fluctuations and discontinuities of emissions. § 21 78 (CLRTAP 2014) Yes
2014 Extend the use of a bibliography for some subsectors to all sectors in the IIR. § 77 (CLRTAP 2014) No The amount of recurring references is very small within most source categories. And the total number of references per page is usually quite low. So directly linking to the documents seems like a good way to make sources available to the readers.
1A1b 2014 Include the country specific EFs for combustion in refineries in the relating chapter of its IIR to improve transparency. § 55 (CLRTAP 2014);DE-1A1b-2017-0001;DE-1A1b-2018-0001 Yes The emission factors continue to be under revision. New emission factors will be included in the IIR following the use of results of a finished project.

5A\5B\5C 2010 Since all incineration is reported under energy add information about the methodology used for different types of waste incineration under NFR 1. In NFR 6C use the notation key “IE” instead of “NO” and to explain the use of the notation key in the IIR. § 103 110 111 112 (CLRTAP 2010);§ 136 (CLRTAP 2014) Yes Information on methods used for estimation of energy-related is reported in NFR 1. Germany considers NO to be correct and explains the situation in its IIR. Cremation estimation is explained now.
Consistency 2 2014 Ensure time series consistency of TSP emissions between 1990 and later years and clearly explain in the IIR where and why consistent reporting is not possible. § 80 (CLRTAP 2014) Yes
1A1\1A2 2010 In the IIR in the “Short description” for 1A1 and 1A2 Germany presents a tier 2 or 3 approach. However during the review Germany indicated that only the tier 2 approach was used. This needs correction in the IIR (was agreed by Germany to do this) § 47 (CLRTAP 2010);§ 54 (CLRTAP 2014) Yes
2A1\2A2 2014 A time series inconsistency is found which relates to a different reporting structure before 2000. It is recommended to explore the feasibility of harmonizing the methodology. § 93 (CLRTAP 2014) Yes
2D3 2014 Provide emissions for 1990-2005 at a disaggregated level similar to later years if possible. If not explain why for the earlier period emissions have been estimated at a more aggregated level. Also clearly document in the case of IE where emissions have been allocated. § 100 101 (CLRTAP 2014) Yes The manufacturing industry was the most important branch of the GDR economy. The transformation of the markets and the disappearance of large state-owned enterprises in the course of the German unity led to a dramatic change in the eastern part of Germany
3B 2014 The ERT encourages Germany to further improve the consistency of the time series of NH3 for manure management. In chapter 4 of the EMEP/EEA Guidebook 2013 specific methods are provided. § 110 (CLRTAP 2014) Yes

Completeness 2010 Emissions prior to 1990 are not reported. § 27 (CLRTAP 2010);§ 24 (CLRTAP 2014) Yes Little information is available due to the split of Germany into two nations. Some overview data has been added to the IIR.
2014 LPS data were not reported. § 10 (CLRTAP 2014) Yes
2014 A key category analysis (KCA) was missing for the base years (1990 or 2000 for PM) of the pollutants. § 13 (CLRTAP 2014) Yes
5E 2010 Although the Guidebook has methods for car and house fires in Chapter 6 it may be more transparent to include these in Chapter 7 as Chapter 6D is more focused on compost and sludge. The ERT encourages Germany to consider including some of these emissions in the next submissions. § 116 (CLRTAP 2010);§139 (CLRTAP 2014);DE-5A-2017-0003 Partly
1A4ai\1A4ci\1A5a 2014 HM and POP currently not reported since no consistent dataset is available (partly country specific partly Guidebook). The recommendation is to describe the issue in the IIR and until it is solved use the Guidebook emission factors despite their recognized uncertainty rather than reporting NE. § 57 (CLRTAP 2014) Yes Implemented for 1A4ai and 1A4ci
1A3ai(i)\1A3aii(i) 2014 Heavy metal emissions are currently not estimated. The ERT recommends that the Party estimates these emissions using the methodology in the EMEP/EEA Guidebook. § 62 (CLRTAP 2014) Yes
1A3biv\1A4bii 2014 PM10 and PM2.5 emissions are reported as “NE”. The ERT recommends that Germany completes the inventory by estimating these emissions. § 63 (CLRTAP 2014) Yes
1A3bv 2014 Evaporative emissions from running losses (i.e. vapour generated in the fuel tank during vehicle operation) were missing because not considered in the TREMOD model. The ERT recommends to include these in the inventory. § 73 (CLRTAP 2014) Yes This issue has not yet been looked into as other model revisions especially regarding a follow-up of 'diesel gate' appear much more relevant tying up all resources.
1A3dii 2014 Pb and Hg emissions are currently not estimated. The ERT recommends that the Party considers the emission factors available in the Guidebook. § 64 (CLRTAP 2014) Yes
5A\5D 2014 Improves the completeness of the inventory by estimating emissions from solid waste disposal and wastewater handling. § 127 (CLRTAP 2014) Yes Solid waste emissions implemented since 2020 reporting. Domestic wastewater emissions implemented since 2018 reporting. Industrial wastewater emissions implemented since 2021 reporting.
5A\5C\5D 2010 The inventory regarding Waste is currently not complete with missing estimates for several source categories. § 102 (CLRTAP 2010);§ 134 135 (CLRTAP 2014) Yes Industrial wastewater emissions implemented since 2021 reporting. Solid waste emissions implemented since 2020 reporting. Domestic wastewater emissions implemented since 2018 reporting. 5.C completed
Comparability 1A4bii\1A4cii 2014 Implied NOx emission factors are at the high end of the range when compared with a selected group of countries (AT BE DK ES FI FR GB IE IT NL NO). The ERT recommends that the Party reviews the emission factors for these two sources and includes an explanation for this issue in the IIR. § 66 (CLRTAP 2014) Yes This minor issue has not yet been checked. The inventory compiler will look into this as soon as resources allow.
1A2a\1A4ai\1A4ci\1A5a 2014 Notation key NE is used for (many) heavy metals despite the availability of EFs in the EMEP/EEA Guidebook. If all HM emissions from iron & steel are reported in 2C1 the notation key should be IE. § 56 (CLRTAP 2014) Yes Implemented for 1A4ai and 1A4ci
Accuracy 2010 Implement a (qualitative and quantitative) uncertainty analysis and use the results to prioritize improvements to the inventory § 20 24 (CLRTAP 2010);§ 32 44e 85 (CLRTAP 2014) Partly
2014 Include a chapter in the IIR with for each source category the foreseen improvements for the inventory § 34 (CLRTAP 2014) Partly Included for most categories
1A3bvi 2014 This source is a key category for Pb and the ERT has noted that the emission factor for brake wear used by Germany was higher than the maximum range quoted by the 2013 Guidebook. Germany is recommended to review the EF explain where it is coming from in the IIR and potentially revise to bring in line with the Guidebook. § 74 (CLRTAP 2014) Yes
1A3dii\1A5b 2014 Review the methodology for national navigation by distinguishing between coastal and inland shipping based on an ongoing research project as well as explicitly include emissions from military activities. § 75 76 (CLRTAP 2014) Yes
2A1 2010 Cement production is a key source for Hg HCB and for NOx PM10 and PAH but Tier 1 is used. The ERT encourages Germany to use plant-specific data collected as part of the LCPD IPPC and E-PRTR to develop a tier 2 or 3 methodology in the near future and to document these in its IIR. § 79 (CLRTAP 2010);§ 88 (CLRTAP 2014) Yes plant-specific data approach is not planned
2D3 2014 Increase the use of information from individual installations that make a high contribution to the key categories such as car assembly sites and big printing installations. § 104 (CLRTAP 2014) Yes Emissions caused by the use of solvents and solvent-based products are reported in the relevant source groups. In our methodology we also include the application of solvent-based products in large installations such as those used in automotive series production or large printing systems. The emission data of defined individual plants are thus included in the calculation but cannot be shown and published individually for reasons of confidentiality and data protection.
3B 2014 Describe the efforts taken to verify / validate the emission model in the IIR. § 118 (CLRTAP 2014) No
QA/QC 2010 Fully implement the QA/QC system for the air pollutant emission inventory. If possible implement a unified QA/QC system for reporting to CLRTAP and UNFCCC. § 21 24 62 74 88 105 (CLRTAP 2010);§ 37 44f (CLRTAP 2014) No Ongoing discussion

2010 Provide more detailed information on the rationale for recalculations at a sectoral level to compliment the information already provided in the recalculation tables per pollutant. § 30 43 90 107 (CLRTAP 2010) Partly
1A2a\1A2b\2C 2010 For iron & steel there is a mix of reporting under 1A2a (PM & CO) 2C1 (NOx SOx VOC NH3) and “NE” (HMs and POPs). For non ferrous metals similar issues are observed. The recommendation is to explain the rationale for reporting in different source categories as well the rationale for NEs. NE reporting should be avoided as much as possible e.g. by applying Guidebook Tier 1 EFs. § 48 49 (CLRTAP 2010) Yes The reporting in the different source categories is explained in the IIR.
1A2gviii 2010 The ERT recommends that Germany include details of the units of AD used in its estimations as this was not always the case. § 51 (CLRTAP 2010) Yes

1A5 2010 The IIR says Tier 1 method is used for 1A5 but it is actually Tier 2/3. This should be corrected in the IIR. § 53 (CLRTAP 2010) Yes
3B 2010 The activity data (animal numbers) is coming from various sources and some corrections are being done. It is recommended that Germany includes a table in the IIR showing the livestock numbers from different sources and the type of elaboration/correction that has been done. § 94 (CLRTAP 2010) Yes
Completeness 2010 Emissions prior to 1990 are not reported. § 27 (CLRTAP 2010);§ 24 (CLRTAP 2014) Yes Little information is available due to the split of Germany into two nations. Some overview data has been added to the IIR.
1A2a\1A2b\1A4\1B1a 2010 Some emissions are not estimated for some pollutants: heavy metals and POPs for 1A2a particulates heavy metals and POPs for 1A2b heavy metals for 1A4 and NMVOC for 1B1a. The ERT recommends Germany to use the Guidebook default EFs if no other method is available. § 36 (CLRTAP 2010) Yes
5E 2010 Although the Guidebook has methods for car and house fires in Chapter 6 it may be more transparent to include these in Chapter 7 as Chapter 6D is more focused on compost and sludge. The ERT encourages Germany to consider including some of these emissions in the next submissions. § 116 (CLRTAP 2010);§139 (CLRTAP 2014);DE-5A-2017-0003 Partly
6 2010 Consider currently missing sources: NH3 emissions from Cats and Dogs from Zoo animals and human ammonia emissions etc. § 116 (CLRTAP 2010) Partly Car and house fires have been included for quite a while now (5E). Human NH3 emissions are considered in 6A. Pets will be considered in sub2024.
1A3a 2010 NH3 reported as NE. Recommendation to investigate the emissions or report as NO if emissions do not occur. § 68 (CLRTAP 2010) Yes The notation key 'NE' is used only for ammonia from aviation gasoline (as recommended in the 2016 EMEP Guidebook). For jet kerosene emissions are estimated.
1B1a 2010 In 2010 “NE” is indicated for particulates and “NA” for NMVOC but the Guidebook has EFs. It is recommended that Germany identifies the type of coal mining using the EFs from the EMEP Guidebook or other references to estimate emissions for this sector. In 2014 NMVOC was reported as NE and the ERT recommends Germany to describe why NE is reported (emissions assumed negligible). § 54 (CLRTAP 2010) Yes

1A2\2 2010 Germany reports emissions from sugar production in source category 2D2. It is recommended to report these emissions under 1A2e and include a more detailed description of the sub-categories the methodology used the source of activity data the source of EFs and consistency across the time series (1990-2008). § 50 (CLRTAP 2010) Yes Reporting of NMVOC and PM emissions from sugar production in 2H2 (used to be 2D2) is correct according to the Inventory Guidebook 2016.
1A3di(ii)\1A4ciii 2010 Emissions reported as IE. The ERT encourages Germany to make separate emission estimates for these sectors in future IIR reports and in the meantime a separate summary table of all categories (fully or partially reported as IE) and where they have been moved would be beneficial. § 69 (CLRTAP 2010) Yes
Accuracy 2010 Implement a (qualitative and quantitative) uncertainty analysis and use the results to prioritize improvements to the inventory § 20 24 (CLRTAP 2010);§ 32 44e 85 (CLRTAP 2014) Partly
