 **CO total emissions** show a falling trend over the whole interval, with emission **reductions of 82.6 %** between 1990 and 2024 and a renewed interval of emission reductions in the last years.  **CO total emissions** show a falling trend over the whole interval, with emission **reductions of 82.6 %** between 1990 and 2024 and a renewed interval of emission reductions in the last years. 
  
-The Main Driver for CO emissions is **Fuel Combustion (NFR 1.A)** with 90% of total 1990 emissions and an 86% reduction between 1990 and 2023. In the Fuel Combustion category, **Road Transport (NFR 1.A.3.b)** is responsible for 57% of the 1990 emissions, with **Passenger Cars (NFR 1.A.3.b.i)** emitting nearly all of it. Reductions of about 90% in those categories between 1990 and 2023 are mainly due to constantly improving fuels and increasingly stricter regulations resulting in technical improvements.  
  
-**Other Sectors (NFR 1.A.4**, including commercial/institutional and residential sources) are responsible for about 27% of 1990 Fuel Combustion emissions with a 84% reduction between 1990 and 2023.+**Main driver** for CO emissions is **Fuel Combustion (NFR 1.A)** with 90% of total 1990 emissions and an 87% reduction between 1990 and 2024. Within NFR 1.A, **Road Transport (NFR 1.A.3.b)** is responsible for 63% of the 1990 emissions, with **Passenger Cars (NFR 1.A.3.b.i)** emitting more than 90% of it. Reductions of about 90% between 1990 and 2024 result mainly from constantly improving fuels and increasingly stricter regulations resulting in technical improvements.
