Graphics from the year 2000 Baltic 21 biannual indicator-based status report on sustainable development in the Baltic Sea Region (Baltic 21 Series No 1/2000). The graphic shows industrial emissions of CO2, which includes Mineral products, chemical industry, metal production, Other production, Production of Halocarbons, Sulphur Hexafluoride and consumption of Sulphur Hexafluoride and Halocarbons.

Sulfur dioxide (SO2) is a colourless gas with a sharp,irritating odour. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores that contain sulfur. There are several areas in the Barents region that have very high amounts of SO2 levels that have caused environmental problems.

A table of the main greenhouse gases and their attributes, sources and concentration levels from 1998. Naturally occurring greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases that are not naturally occurring include hydro-fl uorocarbons (HFCs), perfl uorocarbons (PFCs), and sulphur hexafl uoride (SF6), which are generated in a variety of industrial processes. Water vapour is the most abunda...

Soil degradation is a key global environmental indicator. Trans-border pollution in Europe has become a serious international and environmental problem. Sulphur emissions from industry in Eastern Europe is one of the most environmentally damaging problem that faces countries today.

The following gases are taken into account: CO2 - Carbon dioxide CH4 - Methane N2O - Nitrous oxide PFCs - Perfluorocarbons HFCs - Hydrofluorocarbons SF6 - Sulphur hexafluoride
