Improvements since last Submission

The following changes were new introduced:

  • 1.A.3.b: implementation of biogas as fuel
  • 1.A.3.c: implementation of abrasive emissions from contact line, brakes and wheels
  • 1.A.1.a, 1.A.1.c, 1.A.2.a & 1.A.2.gviii revision of all SO2, NOx, and PM emission factors from 2004 - 2016
  • 2.A.6: revised model of AD conversion of some products from 1996 onwards (Ceramics Production)
  • 2.H.2 (food & beverages): Update of the chapter description
  • 3.B: calculation of cattle NMVOC emission now using Tier 2 emission factors (EMEP, 2016)
  • 3-D: implementation of spreading with trailing shoe on arable land with different incorporation times (see main agricultural page under „Recalculations and reasons“, https://iir-de.wikidot.com/3-agriculture)
  • 5.A: NMVOC and PM2.5 emissions from managed disposal in landfills are reported first time (IIR 2020).
  • 5.D.1: NMVOC emissions from domestic and commercial wastewater handling are reported first time (IIR 2018).
  • 5.D.1: Revision of category due to review-result (IIR 2019).
  • 5.D.1: Revision of AD from 2014 - 2017 due to updated data on annual waste water quantities (IIR 2020).
  • 5.E.2: revised model of AD estimation (Buildings and cars fires)

Improvements planned for future submissions

Possible improvement issues that have been identified so far and will be checked in the future are given below:

Over-all inventory / all source categories:

  • To prioritise improvements on the basis of the results of the uncertainty analysis, it is planned to determine uncertainty analysis at source category level.

Individual source categories:

stationary combustion:

  • Revision of biogas and liquid biomass activities 2004 - 2011 (1.A.1.a) in order to improve time series consistency
  • measurements of POPs and heavy metal in large combustion plants (1.A.1.a)
  • Revision of CO and NH3 emission factors for 1.A.1 and 1.A.2.gviii
  • Revision of SO2 emission factors (1.A.1.b)
  • PAH, PM, CO & VOC measurements in small combustion plants

mobile combustion:

  • implementation of abrasive emissions from tyres, brakes and road surface into TREMOD (1.A.3.b vi + vii)
  • validation and revision of approach for abrasive emissions from railways; possible implementation into TREMOD (1.A.3.c)

fugitives:

  • revision of emission factors within refinery processes

industrial processes

  • collection of AD for Titan dioxide production and calculation of these emissions

Transparency 1.A.3.b i Incorrect notation keys for activity data DE-1A3bi-2018-0002 yes notation keys replaced by activity data values
Transparency 1.A.3.b v Incorrect notation keys for HCB and PCB emissions DE-1A3bv-2018-0001 yes 'NE' replaced by 'NA' as suggested by the TERT

Consistency 1.A.4.c ii IEF Cd trend since 2007 erratic DE-1A4cii-2018-0001 No All issues regarding the inconsistency of activity data from the National Energy Balance (NEB) can only be resolved as soon as the ongoing internal revision process launched by the provider of the NEB has been finished.
Consistency 1.A.4.c ii Inconsistent AD values NFR vs. IIR DE-1A4cii-2018-0001 yes no more inconsistency between NFR and IIR
Consistency 1.A.4.c iii Large increase in AD from 2015 to 2016 DE-1A4ciii-2018-0001 No All issues regarding the inconsistency of activity data from the National Energy Balance (NEB) can only be resolved as soon as the ongoing internal revision process launched by the provider of the NEB has been finished.

Comparability 5.C Hg EF is 100 times smaller than the default value proposed in the 2016 EMEP/EEA Guidebook and the Cd and Pb EF are 1000 times smaller than the default values proposed in the 2016 EMEP/EEA Guidebook DE-5-2018-0001 yes References to research Projects of CS-EF added

Completeness 1.B.2.a iv Potential under-estimate of emissions of Hg, Cd, PCDD/F DE-1B2aiv-2018-0001 No Metal and PCDD/F emissions are not considered as fugitive. If IE would be used nevertheless one can assume there are such fugitives. Germany suggest to keep the notation key NA.
Completeness 2.C.1 Potential under-estimate of emissions of HCB DE-2C1-2018-0001 No Data acquisition could only be implemented in a Project actualizing several emission factors. That Project could not start before 2021 and will last 3 years.
Completeness 2.C.3 Potential under-estimate of emissions of HCB DE-2C3-2018-0001 yes
Completeness 2.D.3.g Report PAHs from 2.D.3.g Chemical Products DE-2D3g-2018-0001 No A project is planned to collect AD and ED for this emission source in order to be able to calculate PAHs emissions. Emission reporting could not be done before submission 2022.

Accuracy 2.D.3.a Rationale for not estimating emissions in category 2.D.3.a and notation key selection DE-2D3a-2018-0001 No Germany is in the process of evaluating data to calculate emissions of Hg from the use of fluorescent tubes.
