- | For Titandioxid production there is a small recalculation for the 2015 and 2016, because of technical problems with the data transfer. | + | Furthermore, CO, NOₓ and TSP emissions are reported for the first time (see also Table 2). |

- | In the NEC Review Germany was requested to calculate emissions of NO,,x,,, CO and TSP from titan dioxid production. Germany tries to collect the data neede to calculate these emissions. | + | ===== Planned improvements ===== |
+ | For 1990 and 1991 for reasons of confidentiality the SOx-emissions were replaced by the emissions value from 1992. Meanwhile the confidentiality does not anymore exist. So for the next submission the real SOx for 1990 and 1991 will be published. |
