-NO<sub>x</sub> **total emissions** show a falling trend from 1990 onwards, with emission **reductions of 66.1%** between 1990 and 2021 and steadily falling emissions in the last years. +NO<sub>x</sub> **total emissions** show a falling trend from 1990 onwards, with emission **reductions of 66%** between 1990 and 2021 and steadily falling emissions in the last years. 
  
-The Main Driver for NO<sub>x</sub> emissions is **Fuel Combustion (NFR 1.A)** with over 91% of 1990 emissions and a 69% reduction from 1990 to 2021. More than half of the 1990 emissions from **Fuel Combustion (NFR 1.A)** and a similar reduction (-73%) between 1990 and 2021 comes from **Road Transportation (NFR 1.A.3.b)**, mainly due to constantly improving fuels and increasingly stricter regulations resulting in technical improvements. +The Main Driver for NO<sub>x</sub> emissions is **Fuel Combustion (NFR 1.A)** with over 91% of 1990 emissions and a 69% reduction from 1990 to 2021.

 The rest of the 1990 emissions mainly comes from **Energy Industries (NFR 1.A.1)** with a 24% share of 1990 Fuel Combustion (NFR 1.A) emissions and a 62% reduction and to a lesser extend from **Manufacturing Industries and Construction (NFR 1.A.2)** with an 12% share and 73% reduction followed by **Other Sectors (NFR 1.A.4)** with a share of 8% in 1.A and a 41% reduction between 1990 and 2021. For **Manufacturing Industries and Construction (NFR 1.A.2)** some emissions were reassigned to the **Industrial Processes (NRF 2)** starting from the year 2000, leading to lower emissions from the energy sector and a similar rise in the Industrial processes. The rest of the 1990 emissions mainly comes from **Energy Industries (NFR 1.A.1)** with a 24% share of 1990 Fuel Combustion (NFR 1.A) emissions and a 62% reduction and to a lesser extend from **Manufacturing Industries and Construction (NFR 1.A.2)** with an 12% share and 73% reduction followed by **Other Sectors (NFR 1.A.4)** with a share of 8% in 1.A and a 41% reduction between 1990 and 2021.
