====== Explanation of Key Trends - Total Suspended Particulate Matter ====== ===== Main drivers ===== Between 1990 and 2022, **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 62% of total 1990 emissions and a 93% reduction between 1990 and 2022 and, as a sum, the **Industrial Processes (NFR 2)** with 27% of the total 1990 emissions and a 67% reduction between 1990 ans 2022. __Table: TSP emissions 1990-2022, in kilotonnes [kt]__ ^ ||||||||||||||||^ Trend: latest compared to || ^ 1990 ^ 1995 ^ 2000 ^ 2005 ^ 2010 ^ 2011 ^ 2012 ^ 2013 ^ 2014 ^ 2015 ^ 2016 ^ 2017 ^ 2018 ^ 2019 ^ 2020 ^ 2021 ^ 2022 ^ 1990 ^ previous year ^ | 2.020 | 543 | 497 | 411 | 379 | 384 | 378 | 386 | 377 | 372 | 345 | 357 | 371 | 346 | 327 | 327 | 330 | -83.6% | +0,9% | {{ :general:trends:iir_tsp_trend.png?direct&800 | trend of TSP emissions, by sector}} {{ :general:trends:iir_tsp_trend_from_2005.png?direct&800 | trend of TSP emissions, by sector, from 2005}}]
