Improvements since Submission 2017

The following changes were introduced since the 2017 annual submission:

  • NFR 1.A.3.b: implementation of biogas as fuel
  • NFR 1.A.3.c: inclusion of abrasive emissions from railways
  • NFR 2.A.6: revised AD for Ceramics Production (2.A.6)
  • NFR 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

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 is in progress; due to the complexity of data acquisition emission reporting could start earliest in submission 2020
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 At the moment, the GB-EF is wrong, but it will be replaced with a correct EF in the GB 2019. The TERT recommends Germany to collect AD for this emission source and to calculate PAHs emissions and to document the methodology as soon as the corrected EF becomes available.

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.
