General Provide a PDF version of the IIR for offline use and to better facilitate the review process § 6, 9, 11, 28 § 17 No The current Wiki platform isn't able to export a whole site to PDF. But we can provide an offline HTML version with full navigation.
General Use the results of the KCA to prioritise improvements in the inventory § 14 Yes
Aspect Sector Finding CLRTAP 2010 CLRTAP 2014 Implemented Comment
Transparency 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 § 19 Partly Information tables for NE & IE were added to the completeness chapter of the current IIR
Transparency Provide more detailed to explain emission trends, e.g. annual fluctuations and discontinuities of emissions. § 21, 78 Yes
Transparency 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 Yes
Transparency Extend the use of a bibliography for some subsectors to all sectors in the IIR. § 77 Partly 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.
Transparency 1A1b Include implied emission factors in the text of the respective chapter rather than referring to other sections in in the IIR. § 55 No Emission factors are under revision. New emission factors will be included in the IIR following completion of the running refinery project.
Transparency 1A2a\1A2b\2C 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 Yes The reporting in the different source categories is explained in the IIR.
Transparency 1A2gviii The ERT recommends that Germany include details of the units of AD used in its estimations, as this was not always the case. § 51 Yes
Transparency 1A3b Explain in more detail the emission calculation for road transport, not only by saying that HBEFA and TREMOD are used but giving more information including an overview of emission factors in the next versions of the IIR. § 65 § 72 Yes
Transparency 1A4 Provide more detail on the emission factors used, including their applicability for the different years and sub-categories of the time series. Find EFs to estimate emissions for heavy metals (for example: using tier 1 in the EMEP Guidebook, inventories in other countries). § 52 Yes
Transparency 1B2d Report in the IIR on what basis emissions from geothermal energy extraction are considered negligible. § 59 Yes
Transparency 2 From the IIR, it is not always clear which specific activities are included in each sector, in particular for Industrial Processes and Solvent use. § 20 Yes
Transparency 2D3 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 Yes The transparency of the IIR for solvent use and product use was much improved in the Submission 2016.
Transparency 3B Explain the variation in activity data for goats in the IIR. § 120 Yes
Transparency 3B The ERT recommends including in the IIR information on the complete time series of the activity data, description of emission drivers, recalculations and improvements for the agriculture sector. § 86, 94 Yes
Transparency 3B Provide additional information in the IIR, especially related to: TAN contents, distributions of housing and storage facilities (e.g. for the first and last reporting year), slurry storage systems and the spreading systems applied, corresponding EFs. § 117 Yes
Transparency 5A\5B\5C 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, 104, 109, 110, 111, 112, 113, 114, 115 § 136 Partly 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.
Aspect Sector Finding CLRTAP 2010 CLRTAP 2014 Implemented Comment
Consistency 1A1\1A2 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 § 54 Yes
Consistency 1A5 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 Yes
Consistency 2 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 Yes
Consistency 2A1\2A2 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 Yes
Consistency 2D3 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 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. The considerable economic and structural differences between East and West following German reunification do not allow a recalculation with the methodology refined in 2000 and 2005, which makes it possible to calculate emissions at a disaggregated level.
Consistency 3B 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 Yes
Consistency 3B Animal numbers show a step change due to a different reporting time. This should be corrected for and described in the IIR as appropriate. § 119 Yes
Consistency 3B Check and explain the variation in activity data for horses in the IIR. § 121 Yes
Consistency 3B 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 Yes
Consistency 3B Explain how the change in farm practices or the implementation of mitigation measures has affected the time series in the IIR in order to facilitate the assessment of emission trends. § 111 Yes
Consistency 3B Explain in the IIR why the NH3 EF for dairy cattle decreased from 2011 to 2012. § 122 Yes
Consistency 3B Explain in the IIR why the NH3 EF for swine decreased from 1993 to 1994. § 123 Yes
Consistency 3B Explain in the IIR why the NH3 EF significant changes for different poultry subsectors in the 2000s. § 124 Yes

Comparability 1A2\2 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 No Reporting of NMVOC and PM emissions from sugar production in 2H2 (used to be 2D2) is correct according to the Inventory Guidebook 2016.
Comparability 1A2a\1A4ai\1A4ci\1A5a 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 Partly Implemented for 1A4ai and 1A4ci
Comparability 1A3di(ii)\1A4ciii 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 Yes
Comparability 1A4aii Emissions for main pollutants were reported as IE. The ERT encourages the Party to investigate further statistical resources for missing estimates in this sector and include a progress report within the next IIR. § 67 Yes
Comparability 1A4bii\1A4cii 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 No This minor issue has not yet been checked. The inventory compiler will look into this as soon as resources allow.

Completeness Emissions prior to 1990 are not reported. § 7, 27 § 24 Yes
Completeness LPS data were not reported. § 10 Yes
Completeness A key category analysis (KCA) was missing for the base years (1990 or 2000 for PM) of the pollutants. § 13 Yes
Completeness Try to estimate emissions for missing sources (now reported as “Not Estimated”), and if this notation key is used explain better the reason why. § 12, 14, 24, 29 § 23, 44a Partly Ongoing effort
Completeness 1A2a\1A2b\1A4\1B1a 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. § 37 Yes
Completeness 1A3a NH3 reported as NE. Recommendation to investigate the emissions or report as NO if emissions do not occur. § 68 Yes The notation key 'NE' is used only for ammonia from aviation gasoline (as recommended in the 2016 EMEP Guidebook). whereas for jet kerosene, emissions are estimated.
Completeness 1A3ai(i)\1A3aii(i) 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 Yes
Completeness 1A3biv\1A4bii PM10 and PM2.5 emissions are reported as “NE”. The ERT recommends that Germany completes the inventory by estimating these emissions. § 63 Yes
Completeness 1A3bv 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 No This issue has not yet been looked into as other model revisions especially as a follow-up of 'diesel gate' appeared much more relevant, tying up all resources.
Completeness 1A3dii Pb and Hg emissions are currently not estimated. The ERT recommends that the Party considers the emission factors available in the Guidebook. § 64 Yes
Completeness 1A4ai\1A4ci\1A5a 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 Partly Implemented for 1A4ai and 1A4ci
Completeness 1B1a 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 Yes
Completeness 2C1 Include emissions for dioxins and heavy metals based on new research project. § 80, 81 Yes
Completeness 3D The ERT encourages Germany to estimate PM10, and PM2.5 emissions for 4D, in future submissions, following the EMEP/EEA Guidebook recommendations. § 86 Yes
Completeness 5A\5B Improves the completeness of the inventory by estimating emissions from solid waste disposal and wastewater handling. § 127 No Ongoing effort
Completeness 5A\5B\5C The inventory regarding Waste is currently not complete, with missing estimates for several source categories. § 102 § 134, 135 No Ongoing effort
Completeness 5D\5E Check if sources which would have to be included under "Other waste" exist in Germany, such as for instance composting, unintentional fires etc. § 139 Yes
Completeness 6 Consider currently missing sources: NH3 emissions from Cats and Dogs, from Zoo animals, and human ammonia emissions, etc. § 116 No

Accuracy Implement a (qualitative and quantitative) uncertainty analysis and use the results to prioritize improvements to the inventory § 20, 24 § 32, 44e, 85 Yes
Accuracy Include a chapter in the IIR with for each source category the foreseen improvements for the inventory § 34 Partly Included for most categories
Accuracy Updating projection data as far as necessary, especially in case of significant recalculations of previous time series. § 31 Yes
Accuracy 1A1b\1A1c\2 Improvement from Tier 2 to Tier 3, using plant-specific data, for some industrial processes including cement production, as well as for large combustion plants (e.g. 1A1b, 1A1c) § 19, 41, 45, 46 Partly Included for large combustion plants, no plant-specific data for cement production
Accuracy 1A3bvi 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 Yes
Accuracy 1A3dii\1A5b 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 Yes
Accuracy 2A1 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 § 88 No No plant-specific data for only two pollutants useful (Hg, PM2.5)
Accuracy 2D3 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 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.
Accuracy 2L Include results of ongoing research project to improve from Tier 1 to higher Tier methodology. § 82, 83 Yes
Accuracy 3B There were errors in the calculation of N excretion rates, it is recommended that Germany corrects this. § 98 Yes
Accuracy 3B Describe the efforts taken to verify / validate the emission model in the IIR. § 118 Yes
