-There are two kinds of processes called chloride process and sulfate process for the production of titanium dioxide. The total production amount is attained from the German Federal Statistical Office [1] For the calculation of individual production of each process, the fraction of chloride process is determined based on the estimated total production capacity in Germany (480kt/y) and the production capacity via chloride process (165kt/y) [2][3].  +

-Because of technical problems with the data transfer, there is a small recalculation for  titanium dioxide production for 2015 and 2016.+Otherwise, no recalculations have been carried out compared to last year's submission.

 ===== Planned improvements ===== ===== Planned improvements =====
  
-In the NEC Review Germany was requested to calculate emissions of NO<sub>x</sub>, CO and TSP from titanium dioxide production. Germany tries to collect the data needed to calculate these emissions. +Since the SO<sub>x</sub> emissions for 1990 and 1991 have so far been subject to confidentiality, 1992 emission values were adopted for these two years.  
- +As this confidentiality does no longer exist, original SO<sub>x</sub> values for 1990 and 1991 will be published with the next annual submission.  
-For the Key Category Analyses the emissions of SO<sub>x</sub> from TiO<sub>2</sub> production are wrongly allocated to 2B10a. Germany plans to reallocate these emissions in the next submission back to TiO<sub>2</sub>.+
