===Emission Factors=== | ===Emission Factors=== | ||
- | Emission factors for Titanium dioxide production are the Tier 2 emission factors from EMEP Guidebook: NOx, CO, and TSP are provided for the chloride process, while only factors for NOx and TSP are available for the sulfate process. The applied Tier 2 emission factors are listed in Table 1 [(European Environment Agency: EMEP/EEA air pollutant emission inventory guidebook 2019, Part B: sectoral guidance chapters, 2.B Chemical industry (Oct 2019): pp.25-26, table 3.19 and table 3.20)]. | ||

- | No category-specific improvements are planned. | + | 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. |
