-The Main Driver for NO<sub>x</sub> emissions is **Fuel Combustion (NFR 1.A)** with over 91% of 1990 emissions and a 73% reduction from 1990 to 2023. More than half of the 1990 emissions from **Fuel Combustion (NFR 1.A)** and a similar reduction (-79%) between 1990 and 2023 comes from **Road Transportation (NFR 1.A.3.b)**, mainly due to constantly improving fuels and increasingly stricter regulations resulting in technical improvements. +**Main driver** for NO<sub>x</sub> emissions is **Fuel Combustion (NFR 1.A)** with over 91% of 1990 emissions and a 75% reduction from 1990 to 2024. About half of the 1990 emissions from NFR 1.A and a similar reduction (-81%) between 1990 and 2024 comes from **Road Transportation (NFR 1.A.3.b)**, mainly due to increasingly stricter regulations resulting in technical improvements. 
  
-The rest of the 1990 emissions mainly comes from **Energy Industries (NFR 1.A.1)** with a 21% share of 1990 Fuel Combustion (NFR 1.A) emissions and a 68% reduction and to a lesser extend from **Manufacturing Industries and Construction (NFR 1.A.2)** with an 10% share and 76% reduction followed by **Other Sectors (NFR 1.A.4)** with a share of 8% and a 46% reduction between 1990 and 2023. 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 23% share of 1990 Fuel Combustion (NFR 1.A) emissions and a 69% reduction and, to a lesser extend, from **Manufacturing Industries and Construction (NFR 1.A.2)** with an 11% share and 69% reduction followed by **Other Sectors (NFR 1.A.4)** with a share of 8% and a 50% reduction between 1990 and 2024.
