Improvements since Submission 2016

The following changes were introduced since the 2015 annual submission:
(R= as follow-up of the review process)

Over-all inventory / all source categories:

  • implementation of emission estimates for Black Carbon (BC): NFRs 1 and 2; EF mostly estimated via default-fractions f-BC as provided in the EMEP/EEA air pollutant emission inventory guidebook 2016
  • Uncertainty Analysis Tier 1 for the NEC pollutants in all categories

Individual source categories:

  • NFR 1.A stationary: Revision of SO2 Emission factors for natural gas and light fuel oil
  • NFR 1.A.4 stationary: update of Emission factors for several main pollutants
  • NFR 1.A.4 stationary: Supplement of HM Emission factors for the years 1990 - 1994 R (GER 2014 Stage 3 RR)
  • NFR 2.A.1 Cement production: already since Submission 2015 emissions of Pb and Cd were reported for the period 1990-1994 instead of notation key “NE” R (GER 2014 Stage 3 RR, para. 89)
  • NFR 2.A.5.b Construction activities: Use of UNECE Guidebook 2016 Tier 1 method to estimate the emissions of particulate matters in an adapted manner
  • NFR 2.D.3 Solvent use: New data were implemented and corrections were made for the calulation of the NMVOC emissions from solvent use.
  • NFR 5.B.1: implementation of NH3-emissions from the category composting R (GER 2014 Stage 3 RR)
  • NFR 5.B.2: implementation of NH3-emissions from the category anaerobic digestion at biogas facilities R (GER 2014 Stage 3 RR)

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:
(R= as follow-up of the review process)

stationary combustion:

  • Revision if the reporting structure of biogas and liquid biomass (1.A.1.a)
  • Possibly measurements of POPs and heavy metal for large combustion plants (1.A.1.a)
  • Improvement of EF for waste incineration plants for 1990 (1.A.1.a)
  • Revision of SO2 emission factors (1.A.1.b)
  • Further comparison of inventory data with PRTR and ETS (1.A.1)
  • Calculation of a complete time series for liquid biomass use (1.A.4.a i)
  • Calculation of a complete time series for biogas use (1.A.4.c i)

Investigated Review Findings

In addition to the above-mentioned improvements as follow-up of the review process, some issues brought up in the Stage 3 Review Report for Germany GER 2014 S3RR (PDF from CEIP.at) were investigated by our experts.

OLD: Improvements since Submission 2015

The following changes were introduced since the 2015 annual submission:
(R= as follow-up of the review process)

Over-all inventory / all source categories:

  • Included level key sources for base year
  • Add trend description for years before 1990
  • Improve consistency in notation key use

Individual source categories:

  • NFR 1.A stationary: Revision of SO2 Emission factors for natural gas and light fuel oil
  • NFR 1.A.4 stationary: update of Emission factors for several main pollutants
  • NFR 1.A.4 stationary: Supplement of HM Emission factors for the years 1990 - 1994
  • NFR 3: further improvements as described under chapter recalculations.
  • NFR 1.A.3.b v: Correction of AD for 1994 R (CLRTAP Stage 2)
