CO2 from the use of soda ash

Emissions of CO2 from the use of soda ash shall be reported to the UNFCCC according to the IPCC Guidelines. In earlier Submissions, Sweden has only reported emissions from the use of soda ash within glass manufacture. In this project contact has been made and data has been collected from several other users of soda ash, for instance moist snuff producers and producers of detergents. Data has also been collected from companies that reported use of soda ash in the trading survey sent by SEPA and SMED in January, and from the Swedish Chemicals Inspectorates (KemI). New calculations of CO2 from the use of soda ash were made for the time series 1990-2003 based on data from KemI for all sectors except from glass manufacturers, where the data already available from earlier submissions were used. The new time series show a lot higher emissions than in Submission 2004, but still CO2 emissions from the use of soda ash is only about 1 % of the total CO2 emissions in the Industrial Process sector.
