| - | For the **production of titanium dioxide**, the producers report the sum of all SO₂-emissions. | + | |

| + | Emission factors for Titanium dioxide production are the Tier 2 emission factors from EMEP Guidebook: NO< | ||
| + | |||
| + | 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)]. | ||

Furthermore, | ||
| - | Because of technical problems with the data transfer, there is a small recalculation | + | As the SO₂ emissions from titanium dioxide are no longer confidential, they are reallocated from 2.B.10 to this category (see Table 2 ). |
