-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.  +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.
