Definitions & Technical notes:
Data on emissions of SO2 are usually estimated according to international methodologies on the basis of national statistics on energy, industrial and agricultural production, waste management, etc.
The most widely used methodologies are the 1996 Guidelines of the Intergovernmental Panel for Climate Change (IPCC) (see http://www.ipcc-nggip.iges.or.jp/public/gl/invs1.html) which is the basis for reporting to the UNFCCC. The latest revision and update of this guideline is 2006 IPCC Guidelines for National Greenhouse Gas Inventories (see http://www.ipcc-nggip.iges.or.jp/public/2006gl/index.htm). In earlier years the guidelines produced for the UNECE Convention on Long Range Transboundary Air Pollution were widely used in Europe, and are still used in some countries. The main source of SO2 is burning of fuels, including biomass.
SO2
emissions per capita is calculated by UNSD.
Data Quality:
Standardised methods for calculating SO2 emissions from fuel combustion have been available for many years. The amount of SO2 emitted is directly related to the sulphur content of the fossil fuels consumed in the country, and the desulphurisation techniques used, if any. Data on emissions from fuel combustion are considered to be reasonable.
