-By far the largest proportion of SO<sub>2</sub> is produced by the oxidation of the sulphur contained in the fuels used in combustion processes, **Fuel Combustion (NFR 1.A)** with a 96% share of total SO<sub>2</sub> emissions in 1990 and a 97% reduction between 1990-2021. +SO<sub>2</sub> **total emissions** show a falling trend from 1990 onwards, with **emission reductions of over 95% since 1990**.

 In 1990, the biggest source of emissions therein is **Public Electricity and Heat Production (NFR 1.A.1.a)** with about 60% of the emissions from **Fuel Combustion (NFR 1.A)**. Other sources substantially influencing the SO<sub>2</sub> emission trend are **Manufacturing Industries and Construction (NFR 1.A.2)** and **Other Sectors (NFR 1.A.4**, including commercial/institutional and residential sources), each adding about one fifth of 1990 emissions from Fuel Combustion (NFR 1.A).  In 1990, the biggest source of emissions therein is **Public Electricity and Heat Production (NFR 1.A.1.a)** with about 60% of the emissions from **Fuel Combustion (NFR 1.A)**.

 All of these sub-categories show a reduction >95 per cent between 1990 and 2021, due to stricter regulations of West Germany that applied to the New German Länder after the German Reunification and changed the fuel mix from sulphur-rich solid fuels to liquid and gaseous fuels. All of these sub-categories show a reduction >95 per cent between 1990 and 2021, due to stricter regulations of West Germany that applied to the New German Länder after the German Reunification and changed the fuel mix from sulphur-rich solid fuels to liquid and gaseous fuels.
