Improvements since 2012 Submission

The following changes were introduced since the 2012 Submission, mainly due to review activities:

  • Establishment of an annual work programm, to prioritize and organize improvements for greenhouse gases and air quality pollutants (QA/QC)
  • Uncertainty analyses for PM10, PM2.5, NOX, SO2, NMVOC and NH3
  • Newly reported emissions from liquid biomass combustion (NFR 1.A), as a result of a gap-filling procedure
  • Revision of SO2 emission factors from lignite fired power plants (NFR 1.A)
  • Inclusion of particle exhaust emissions from gasoline-driven road vehicles (NFR 1.A.3.b)
  • Revision of CNG and LPG use in road transport (NFR 1.A.3.b)
  • change of the animal counting method, update of the N flux concept for animal husbandry & updated animal performance data, new modelling of anaerobic digestion and the storage of digested slurry (4.B)
  • Introduction of biodigesters as new animal waste management system (NFR 4.B)
  • Addition of Particle Emissions from Coal Production (NFR 1.B.1.a)
  • Addition of Particle Emissions from Mining other than Coal (NFR 2.A.7.a)

Planned for future submissions

The key instrument to systematically identify and adress issues for improvement is a functioning QC/QA-System as exemplarily pointed out by the IPCC Good Practice Guidance. Consequently one of the major goals aspired by Germany is the entry into force of such a system for the reporting under UNECE-CLRTAP. Since extensive labor is needed to elaborate a well established instrument that serves the desired needs, such undertaking takes time. Out of that reason and due to limited resources germany intends to establish a quality system on a step by step basis.

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:

Individual source categories:

  • Updating the database for emission factors of LCP (NFR 1.A)
  • Developement of a new calculation model for biogas fired plants (NFR 1.A)
  • Revision of emission factors for gasoline-driven off-road mobile sources (NFRs 1.A.2.f ii, 1.A.4.b ii, 1.A.4.c ii etc.)
  • Inclusion of particle exhaust emissions from gasoline-driven vehicles and mobile machinery (NFRs 1.A.2.f ii, 1.A.4.b ii, 1.A.4.c ii etc.)
  • Inclusion of emissions from LPG-driven forklifters (NFR 1.A.4.b ii)
  • Revision of emission estimates for solid fuels in railways (NFR 1.A.3.c)
  • Separate reporting of AD and EM for commercial / institutional mobile sources (NFR 1.A.4.a ii)
  • Particle emissions from flaring in oil production plants and refineries (NFR 1.B.2.a)
  • VOC emissions from cleaning of tank cars (NFR 1.B.2)
  • Revision of mineral fertilizer production (NFR 2.B.5 Other)
  • Inclusion of mercury emissions from chlorine-alkali industry (NFR 2.B)
  • Relevance of NMVOC (NH3) from wastewater (latrines) (NFR 6.B)
