====== Explanation of Key Trends - Total Suspended Particulate Matter ======

===== Main drivers =====

Between 1990 and 2021, **total TSP emissions dropped by 83.6%**, mainly due to stricter regulations of the Old West Germany that applied to the New German Länder after the German Reunification and realized a change-over from solid to gaseous and liquid fuel, as well as advancements in filter technologies of combustion plants and industrial processes. 

The Main Drivers for TSP emissions are **Fuel Combustion (NFR 1.A)** with 61% of total 1990 emissions and a 94% reduction between 1990 and 2021 and, as a sum, the **Industrial Processes (NFR 2)** with 28% of the total 1990 emissions and a 68% reduction between 1990 ans 2021.
