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:

  • measurements of POPs and heavy metal in large combustion plants (1.A.1.a)
  • Revision of SO2 emission factors (1.A.1.b)
  • Revision of PAH Emission factors for 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)

industrial processes

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